12 years later this video is still helping people. Thank you so much! I was so focused on the compressor that I failed to realize my pressure sensor was chewed through by mice.
Richpin you are a beautiful person. I have a 01 SC and I've never come across a video I couldn't find an answer to from googling "Richpin [problem keywords]". Hopefully I can use this to figure out why my AC hasn't worked yet this year. Thank you!
This is a great set of videos! Before watching these two videos I literally knew next to nothing about AC. Not anymore. I think I might actually be able to get my AC back up and running! Thanks for posting these very detailed and helpful videos!
You’re a genius! I think this is the first time the compressor motor has spun in years. I jumped it with a paper clip turned it on and Bam! It actually started turning. Being low on charge apparently prevents the motor from turning? I think I have no pressure in the lines as there is no cold air at all. I believe I’m going to be able to recharge it now. Thanks again!
Thanks very much for the video. I was able to successfully troubleshoot my system and isolated fault to a bad compressor clutch relay. Living in Louisiana having functioning AC is a life saver! Thanks again
I love you! Thanks so much for your videos. You have helped me save so much money and taught me how to work on my car. My Saturn is 16 years old and still going strong. I run into problems with her acting up but with your videos I am able to find a solution to the problem.
Thanks very much for this informative video. You helped me isolate the problem -- my low pressure switch went bad. Replaced it ($9 at parts store), and we're back in business. Thanks again!
The most common reason A/C systems stop working is there is a leak somewhere in the system.What i do is put enough refrigerant with dye in the system to get the compressor to turn on then look for the leak.
Thank you for your video. I used it to diagnose a problem on my 1996 chevy blazer. The clutch on the AC unit was not turning on, and it was blowing warm air. Once I used the paper clip to bypass the relay I was able to reset the clutch, and then I could charge the AC with new refrigerant. I found that there is a leak and that's why I ran out of refrigerant. Thanks for all of your help. It helped me to get on my way to solving my problems. Excellent video.
Hey rich...i have a 99 saturn sl and because of all your great videos...I have replaced my radiator,water pump and some other minor things that would not have been possible if not for the hard work and time you put in to all your videos. Thank you and please keep those videos coming. "especially for that saturn sl you work on".......V
Hi Rich!!! You are a real Master!!! Congratulations from México. Doing all this steps I can Fix my Windstar ´96 AC System!!! Best Regars!! You got a new fan.
Without reading the high side it makes it a little differcult to see whats going on.If i were to make a guess i would say there is air in there which probably means you have a hole somewhere in the system.You need to start from scratch put a can of refrigerant with dye in and check for leaks.When you find it replace the part.evacuate and charge the system.
@pontiachotshot To check put your gauge set on first then see what the reading is not running.If it is at zero start the car turn on the A/C and put in one 12oz can of refrigerant with dye and check for leaks.Always check your gauges if the temperature is 90 deg(f) do not go over 270psi on the high side at 2000 rpm.
Thank you for the good video. In my 2008 Sienna, clutch was not engaging, so I added one can of RedTek 12a, the pressure was on blue and clutch engaged and AC system worked fine for few months(original gas was 134a). Then it stopped blowing cold air. I checked the low side pressure , it was 100 psi. clutch is engaged but no cold air, the compressor turns normal without noisy sounds. I made the low side pressure zero(evacuate the system using the hose, without allowing any humidity in), then I filled the system with one RedTek 12a can(454 g), the pressure went up to about 80 psi, then the clutch engaged, compressor is very smooth, but no cold air. I added another can, pressure up to 100 psi(low side), but still no cold air. I touched the low side pipe, not cold.. I touched the high pressure side pipe that is coming out of compressor, it is not hot.. Wondering, what is going on with this AC system, is the problem in the AC compressor it self, or one of the expansion valves is faulty and wide open, as this vehicle has rear air conditioning. Thank you
hello i like your video its really2x useful... thank you very much for making a step by step procedure i hope you show more video to share...your a top aircon mechanic
First thing i would do is check the pressure if there is none there is a leak somewhere.To find it use refrigerant with dye.Hook up your hose from the can to the low port with the engine off.Turn on the A/C and start the engine.Then turn the valve handle to pierce the can then turn the valve to permit the refrigerant to enter the system.
The pieces you are missing are: heater box (HVAC module),hoses,compressor,condenser. Important Update: Jan 1 2013 there will be a new richpin channel for all future videos.Richpin06a channel will be solely for all the Saturn lovers out there.Should be a lot of fun so stay tuned.
Good video Rich My Saturn SL2 1997 Has a leak somewhere. I install a new compressor and tried charging the system but it was low on refrigerant. So my clutch doesn't engage. I wasn't getting voltage at the compressor. So I went to the pressure switch and bypass it. My clutch did engage. So I guess I will bypass the switch until I get enough freon with dye in it. And then maybe I will have enough freon in the system. 😇😇😇😇😇😇
If the compressor clutch is engauging like you said then it is a possibility the bulb is burnt out in the switch.The only way to tell what is going on with your air conditioning system is to put a gauge set on it.
richpin06a I actually found out it was a wire that had been chewed on by something when my car sat for a year, but now its the switch preventing the clutch from engaging because when i jumped it with the paper clip it engaged. what can i do about that switch?? thanks so much
If you have voltage at the connector and the clutch is not engaging then run a jumperwire from your battery to the clutch itself and see if it engages. I have seen in the past where I had voltage at the connector but not enough amperage to engage it because my ac relay contacts were bad.
I have a 2000 ford ranger. The a.c will attempt to work on startup of the truck, for 3 seconds the clutch will engage and will only if reengage if i turn off the truck and start it again. paperclip trick don't work (pressure switch) refrigerant is good, i know this by running 2 wires directly from the battery to the clutch while the truck is running. the reading on the low side was 35 and the high side 200
If the fan does not run and you come to a stop there is no air being drawed through the condenser which will result in very little cooling in the cabin.
hi, Rich i learned a lot from you, from changing the water pump, brakes, cleaning egr and so on it saves me a lot of moneyand i am very thankful of that; i have one question though my saturn a/c suddenly stop working is it possible that low or lack of refrigerant will cause the clutch in the compressor not to spin?
Hey Rich- thanks for the great videos. When testing the power to the compressor does it make any difference while hole to put the jumper pin in ... And then testing with vm. Thanks-jeff
Great instructional video Rich. Unfortunately I have the same problem with my 1998 SC2 that jednootenboom has above. Every item checks good, compressor operating, pressure switch ok, relay operating, fuses good, low side charge is @ 45-50, still no cold air. Question, what would typical range for high side side pressure be?
The connection is under the compressor on the lower part of the engine. I did get the connection off, and tried to connect each pin to ground through the ohm meter and never found where it was grounded. I also switched the relay with another relay (same number) ran the car for awhile, and the ac worked for about 2 minutes and blew the fuse again.
Hi great video. I unplugged the coolant sensor and found the connector to have the green corrosion you talked about. I can't just clean this off and replace the sensor?
Excellent video! Learned so much in just a few minutes! ? I have a 1999 Honda Civic LX. Is there a high and a low pressure switch? Where are they located?
I have a 99 Saturn SC2 coupe with 63, 400 mi on it had to replace frame broke a transmission mount the car is in great shape seats interior are perfect replaced all front end parts but it still wants to dark on the road left or right when you hit a line or a hump
Thanks Rich! Narrowed it down. Pressure switch is good. Plenty of freon. There is current at the clutch when engaged. Means the clutch is toast. Guess I'll look for best deal on a compressor, and guy a can of freon, right? Thanks again sir.
Priced it. Same price. Gotta buy clutch from manufacturer but after market compressor including clutch and I'm not sure the compressor will not go out soon. So why not replace whole thing? Or should I figure much easier to replace clutch and no need to do freon too? I took it to shop and they wanted 800 bucks to fix it. So I've done without so far... Thanks for advice
@richpin06a, just got this 1997yr and model sl2 for nothing. Having a few troubles tbough and your videos have helped a great deal so far. One problem is the ac and I had a question about jumping the clutch with paper clip. Does the car need to be started? I ask because i jumped it with car off and it didn't engage just want to make sure I am doing this right before buying a new clutch or compressor. Speaking of, do you have a video showing how to replace the clutch and the entire compressor?
My L Series has a 3 pin P.S. with Red, Black And White wires to the connector. I did try touching them with my multimeter and did get a 0.00 reading at one point but couldn't see what ones I was testing. You can't see them well like on an S Series. It does have a charge because the compressor was working before it froze up 2 days ago. The clutch wouldn't turn. Now no clutch engaging on the reman compressor. I vacuumed and tried to recharge it and still nothing. Doesn't make sense. Swapped relays and diodes too.
I am trying to use the video to diagnose the AC on my suburban. I replaced the AC belt and the tensioner that was frozen. The AC clutch kicks on and off every few seconds or so but the AC still blows hot. The simple gauge on the top of recharge system tells me that the one side of the system is in ALERT(as if it's overcharged). I know there are shrader valves and I can release some pressure but did not want to do that quite yet. I did not put any refrigerant in the system at all. They belt has been broken for about a year so the compressor and clutch were not running for a year but do appear to be working from just a visible inspection of the compressor spinning as well as the AC clutch engaging every few seconds. Any thoughts on my next step to diagnose, why it tells me ALERT on the refill side?
Richpin, I got a Recharge kit/can w hose adapter. Do I start filling the a/c tank w/out starting the vehicle, to build up some pressure first? Or should I start the vehicle, then release the fluid? I've got the saturn w/out continuity showing at the pressure switch. Thx again, trying not to make mistakes...Frank, $300 Saturn Sl2
aaaahh........i guess yes.......the system dont have any pressure........and then...i dont not where is the location for the swithc pressure.........it is honda accord.95 please help me.......thank you
I have a 00 Saturn SL2 that has stopping blowing cold air. I haven't put in new Freon in about 10 years so we thought it was low.We bought one of those all in one cans of coolant at walmart and hooked the gauge up to the low side...well the reading is in the RED.When I turn on the AC it blows hot air and all the belts spin.I do hear a faint ticking nose from where the pressure switch/battery area is. Any thoughts? Is it safe to drive?
Nice videos.My a/c works great when it's in the low 80's but 90 or higher it starts acting up,probe jumps to 55-60degress, and here are the symptoms when it's a hot day.I did notice on start-up,the compressor starts and stops 10 times with-in the 1st 2 minutes,then 4 more with-in the next 2 minutes,then compressor stops cycling. If I drive at 55mph or lower I get cooler air,but over 55 the air starts cycle from cool to slightly warmer.No leaks and it's been recharged.Any ideas?
Hey Richpin, love your videos, but I'm having a very odd problem with my ac. when you have the car on and turn on the fan by itself after a while, the IGN 3 fuse blows under the hood and stops power to a bucnch of things. Any ideas why this might be happening? thanks
Dear sir, THANK YOU SO MUCH FOR THE GREAT VIDEO! IT WAS VERY HELPFUL! by Amy chance do you have a video on a 2013 Chevy silverado trouble shooting like for the Saturn?
hi rich great video as all, what's the name of the ignition fuse that's located in the interior junction box? you said others words, I couldn't understand them , can you writer them , thank you rich,cheers from ontario calif,
Hey rich, I have 12 volts to the a/c compressor so I suspect the clutch is bad. Is there a way to confirm its the clutch and not a seized or bad compressor? Also if it is the clutch, do I need to remove the compressor to replace the clutch or can I keep it bolted on and just pull the clutch?
I have a 2003 Mitsubishi Lancer ES. My A/C problem seemed to be when my car is at a stand still. I have 2 condenser fans motor and I have seen both of them turn on and off which tells me that they are working..... possibly not working right but at least I seen them clicking on and off? But when I'm driving my A/C is nice and cold. I mean really really good COLD air but once I stop the vent slowly starts to pull in some warm air. I do have experience in the HVAC (residential, commercial, and industrial) but I know auto A/C has the same principle but it is a little different as well compare to a home unit. I just hate to base my reading off of my gauges when in fact I probably have a air flow problem and don't wanna assume I overcharge the system, undercharge, or have a clogged system. I did investigate my condenser which looks to be in good condition and may be a little dirty which I'll clean shortly but nothing out of the ordinary. My question is what could possibly be the problem? The last thing I don't want is a clogged system but like I've said before my car has no problem at all cooling down when I'm driving. Any help would really be appreciated!!!
there's a lot of things involved in a/c it coul be a high presure or low presure switch. or a relay or the compressor it self o may be low refrigerant olso a fuse it's a pain in the rear
Hi, I hope you can answer my question so that when I walk into a repair shop, I won't be so clueless, therefore, be taken advantage of financially. I have a 2007 Toyota Corolla and anytime I turn on the a/c and make only LEFT turns, it makes a noise like sand or a fizzing sound. Nothing is stuck under the carriage of the car, I checked, as well as under the hood, plus when I turn off the a/c and turn left, no noise. Thank you for any help you can offer.
In replacing my radiator on my 96 SL -- I couldn't navigate the radiator back in and "bent" my low charge AC line causing it to leak at the compressor. How difficult is it to replace the AC lines -- andy tips/special tools -- and do you have a video on this topic.. thanks again for the videos you have posted -- they have save me time and aggravation..
12 years later this video is still helping people. Thank you so much! I was so focused on the compressor that I failed to realize my pressure sensor was chewed through by mice.
Update, 14 years. Thanks richpin
Richpin you are a beautiful person. I have a 01 SC and I've never come across a video I couldn't find an answer to from googling "Richpin [problem keywords]".
Hopefully I can use this to figure out why my AC hasn't worked yet this year. Thank you!
GlowingNinja A/C is not my specialty so i do not know all the answers there.Googling Richpin is funny though.
This is a great set of videos! Before watching these two videos I literally knew next to nothing about AC. Not anymore. I think I might actually be able to get my AC back up and running! Thanks for posting these very detailed and helpful videos!
Rich, I love your videos. I have two saturns and have been watching your saturn videos for over a year. Thank you!

Thanks again!
oh you r priceless! God is smiling at u for helping others like this
But then why did god give him wrinkled hands?
@92Countryb There is not enough of air blowing over the condenser when the car is not moving to give you cold air, very common on the Saturn.
Thanks very much for the video. I was able to successfully troubleshoot my system and isolated fault to a bad compressor clutch relay. Living in Louisiana having functioning AC is a life saver! Thanks again
I love you!
Thanks so much for your videos. You have helped me save so much money and taught me how to work on my car. My Saturn is 16 years old and still going strong. I run into problems with her acting up but with your videos I am able to find a solution to the problem.
I am glad i could help.
Great video! Thanks! No nonsense, clear, and straight to the point. Very much appreciated! Looks like the clutch on our compressor is bad.
Thanks very much for this informative video. You helped me isolate the problem -- my low pressure switch went bad. Replaced it ($9 at parts store), and we're back in business. Thanks again!
Thanks' You are already on the service people
I wish you every happiness in your life gentleman
Greetings
@TheBboytwister Checking the switch is to see if the switch is closed and the connector for voltage to operate the compressor clutch.
Man, I've got a Saturn SC1 just like in this and these videos are a lifesaver.
This video got me pointed to the pressure shutoff switch, fixed the issue on my wife's truck. Thanks for making it!
The most common reason A/C systems stop working is there is a leak somewhere in the system.What i do is put enough refrigerant with dye in the system to get the compressor to turn on then look for the leak.

After I jumped the switch I compressor kicked on but would not take any freon
Hey rich...i have a 99 saturn sl and because of all your great videos...I have replaced my radiator,water pump and some other minor things that would not have been possible if not for the hard work and time you put in to all your videos.

Hi Rich!!! You are a real Master!!! Congratulations from México. Doing all this steps I can Fix my Windstar ´96 AC System!!! Best Regars!! You got a new fan.
Thank you so much, this helped me fix my A/C, Arizona heat does not play around when you gotta go somewhere.
Without reading the high side it makes it a little differcult to see whats going on.If i were to make a guess i would say there is air in there which probably means you have a hole somewhere in the system.You need to start from scratch put a can of refrigerant with dye in and check for leaks.When you find it replace the part.evacuate and charge the system.
good speaking &good video and your explanation, to how we can find out the trouble.thanks
very easy to follow step by step. thank you.
Thank you for your hard work.
Thank you very much Mr, Richpin,
Awesome video! thanks a lot, A/C is blowing could now!
Thanks for the tips, Baaaston. Helped me solve a problem on a Saturn.
just amazing, thank you so much you made my day 10+
@acanalesp I am using a craftsman multimeter to do the electrical tests.
Thanks richpin. Great video!
Thank you my friend.
@pontiachotshot To check put your gauge set on first then see what the reading is not running.If it is at zero start the car turn on the A/C and put in one 12oz can of refrigerant with dye and check for leaks.Always check your gauges if the temperature is 90 deg(f) do not go over 270psi on the high side at 2000 rpm.
Thank you for the good video. In my 2008 Sienna, clutch was not engaging, so I added one can of RedTek 12a, the pressure was on blue and clutch engaged and AC system worked fine for few months(original gas was 134a).
Then it stopped blowing cold air. I checked the low side pressure , it was 100 psi. clutch is engaged but no cold air, the compressor turns normal without noisy sounds.
I made the low side pressure zero(evacuate the system using the hose, without allowing any humidity in), then I filled the system with one RedTek 12a can(454 g), the pressure went up to about 80 psi, then the clutch engaged, compressor is very smooth, but no cold air.
I added another can, pressure up to 100 psi(low side), but still no cold air.
I touched the low side pipe, not cold.. I touched the high pressure side pipe that is coming out of compressor, it is not hot..
Wondering, what is going on with this AC system, is the problem in the AC compressor it self, or one of the expansion valves is faulty and wide open, as this vehicle has rear air conditioning. Thank you
Thanks Richpin you are a life saver!!!!!
hello i like your video its really2x useful... thank you very much for making a step by step procedure i hope you show more video to share...your a top aircon mechanic
Excellent videos Thank You!!
i like ur videos, you know what u r doing
realy simple troubleshoting methods//// Thanks .....
You helped me pass my smog test.
@MrRaiders6769 I have not run into this one,is the check engine light on.
First thing i would do is check the pressure if there is none there is a leak somewhere.To find it use refrigerant with dye.Hook up your hose from the can to the low port with the engine off.Turn on the A/C and start the engine.Then turn the valve handle to pierce the can then turn the valve to permit the refrigerant to enter the system.
Is there voltage at the electrical connector at the compressor.
Yes it will.
@gpcdist Are you getting continuity trough the switch
I would use a multimeter on the ohm scale with the wire disconnected from the clutch and check to see if the clutch coil is shorted to ground.
The pieces you are missing are: heater box (HVAC module),hoses,compressor,condenser.
Important Update: Jan 1 2013 there will be a new richpin channel for all future videos.Richpin06a channel will be solely for all the Saturn lovers out there.Should be a lot of fun so stay tuned.
What are the high and low pressure readings of your system.
If you can move center piece which is the clutch then the compressor might not be seized.What make year vehicle are you working on.
Good video Rich
My Saturn SL2
1997
Has a leak somewhere.
I install a new compressor and tried charging the system but it was low on refrigerant.
So my clutch doesn't engage.
I wasn't getting voltage at the compressor.
So I went to the pressure switch and bypass it.
My clutch did engage.
So I guess I will
bypass the switch until I get enough freon with dye in it.
And then maybe I will have enough freon in the system.
😇😇😇😇😇😇
If the compressor clutch is engauging like you said then it is a possibility the bulb is burnt out in the switch.The only way to tell what is going on with your air conditioning system is to put a gauge set on it.
Jared Bonner,The IGN3 fuse on the s-series feeds into the A/C relay so i might start at that point.
richpin06a I actually found out it was a wire that had been chewed on by something when my car sat for a year, but now its the switch preventing the clutch from engaging because when i jumped it with the paper clip it engaged. what can i do about that switch?? thanks so much
Jared Bonner Could it be your system is low on charge that is why the switch is not passing voltage..
Help me trace back to a bad relay. Thanks for the help!!
Is the cooling fan working.
@92Countryb Maybe mounting a fan in front of the condenser might help MAYBE.
thanks for the video
Excellent
I think that is a fair assumption.You could check that by see what the ground control from the PCM is doing at relay pin at the fuse box.
The power should be on the pin at the compressor electrical connector with the green wire going to it.
If you have voltage at the connector and the clutch is not engaging then run a jumperwire from your battery to the clutch itself and see if it engages. I have seen in the past where I had voltage at the connector but not enough amperage to engage it because my ac relay contacts were bad.
I have a 2000 ford ranger.
The a.c will attempt to work on startup of the truck, for 3 seconds the clutch will engage and will only if reengage if i turn off the truck and start it again.
paperclip trick don't work (pressure switch)
refrigerant is good, i know this by running 2 wires directly from the battery to the clutch while the truck is running.
the reading on the low side was 35 and the high side 200
What is the high side reading.
If the fan does not run and you come to a stop there is no air being drawed through the condenser which will result in very little cooling in the cabin.
Have you troubleshooted the compressor clutch to see if that is were the fault lies.
You can get a multimeter like the one i am using from Sears.
@fbruno082 What year and make Saturn do you have.
hi, Rich i learned a lot from you, from changing the water pump, brakes, cleaning egr and so on it saves me a lot of moneyand i am very thankful of that; i have one question though my saturn a/c suddenly stop working is it possible that low or lack of refrigerant will cause the clutch in the compressor not to spin?
Hey Rich- thanks for the great videos. When testing the power to the compressor does it make any difference while hole to put the jumper pin in ... And then testing with vm.
Thanks-jeff

Excellent video! Learned so much in just a few minutes!
? I have a 1999 Honda Civic LX. Is there a high and a low pressure switch? Where are they located?
@techtimevlog No it's OH MY GOD ITS RAY ROMANO the A/C guy
If the blower does not come on when you turn the fan switch on i would start at the blower motor checking for voltage and ground.
Mine was the resistor a very cheap part and common fault on my vehicle. It's all working now.
@Haiti News Info Haiti News Info www.ebay.co.uk/itm/153852633448 it's supposed to stop the wires burning out.
I have a 99 Saturn SC2 coupe with 63, 400 mi on it had to replace frame broke a transmission mount the car is in great shape seats interior are perfect replaced all front end parts but it still wants to dark on the road left or right when you hit a line or a hump
Thanks Rich! Narrowed it down. Pressure switch is good. Plenty of freon. There is current at the clutch when engaged. Means the clutch is toast. Guess I'll look for best deal on a compressor, and guy a can of freon, right?

Hi Rich, do you know if the 2001 SC2 has a cabin a/c filter?
Richpin, I got a Recharge kit/can w hose adapter. Do I start filling the a/c tank w/out starting the vehicle, to build up some pressure first? Or should I start the vehicle, then release the fluid? I've got the saturn w/out continuity showing at the pressure switch. Thx again, trying not to make mistakes...Frank, $300 Saturn Sl2
aaaahh also i check all fuses and they are good..............what the problem.......the fan two working.....good.......thank you.
Have you checked the pressure in the system.
aaaahh........i guess yes.......the system dont have any pressure........and then...i dont not where is the location for the swithc pressure.........it is honda accord.95 please help me.......thank you
I have a 00 Saturn SL2 that has stopping blowing cold air. I haven't put in new Freon in about 10 years so we thought it was low.We bought one of those all in one cans of coolant at walmart and hooked the gauge up to the low side...well the reading is in the RED.When I turn on the AC it blows hot air and all the belts spin.I do hear a faint ticking nose from where the pressure switch/battery area is.

Nice videos.My a/c works great when it's in the low 80's but 90 or higher it starts acting up,probe jumps to 55-60degress, and here are the symptoms when it's a hot day.I did notice on start-up,the compressor starts and stops 10 times with-in the 1st 2 minutes,then 4 more with-in the next 2 minutes,then compressor stops cycling.
If I drive at 55mph or lower I get cooler air,but over 55 the air starts cycle from cool to slightly warmer.No leaks and it's been recharged.Any ideas?
Hey Richpin, love your videos, but I'm having a very odd problem with my ac. when you have the car on and turn on the fan by itself after a while, the IGN 3 fuse blows under the hood and stops power to a bucnch of things. Any ideas why this might be happening? thanks
Dear sir, THANK YOU SO MUCH FOR THE GREAT VIDEO! IT WAS VERY HELPFUL! by Amy chance do you have a video on a 2013 Chevy silverado trouble shooting like for the Saturn?
I do not at this time but i am always adding new videos.
@OMGUSERFREAKINGNAME I do not as i have never replaced a compressor clutch sorry.
hi rich great video as all, what's the name of the ignition fuse that's located in the interior junction box? you said others words, I couldn't understand them , can you writer them , thank you rich,cheers from ontario calif,
Hey rich, I have 12 volts to the a/c compressor so I suspect the clutch is bad. Is there a way to confirm its the clutch and not a seized or bad compressor? Also if it is the clutch, do I need to remove the compressor to replace the clutch or can I keep it bolted on and just pull the clutch?
If the center the pulley (clutch)
is not turning you need a new clutch.
I have a 2003 Mitsubishi Lancer ES. My A/C problem seemed to be when my car is at a stand still. I have 2 condenser fans motor and I have seen both of them turn on and off which tells me that they are working..... possibly not working right but at least I seen them clicking on and off? But when I'm driving my A/C is nice and cold. I mean really really good COLD air but once I stop the vent slowly starts to pull in some warm air. I do have experience in the HVAC (residential, commercial, and industrial) but I know auto A/C has the same principle but it is a little different as well compare to a home unit. I just hate to base my reading off of my gauges when in fact I probably have a air flow problem and don't wanna assume I overcharge the system, undercharge, or have a clogged system. I did investigate my condenser which looks to be in good condition and may be a little dirty which I'll clean shortly but nothing out of the ordinary. My question is what could possibly be the problem? The last thing I don't want is a clogged system but like I've said before my car has no problem at all cooling down when I'm driving. Any help would really be appreciated!!!
there's a lot of things involved in a/c it coul be a high presure or low presure switch. or a relay or the compressor it self o may be low refrigerant olso a fuse it's a pain in the rear
Hi, I hope you can answer my question so that when I walk into a repair shop, I won't be so clueless, therefore, be taken advantage of financially. I have a 2007 Toyota Corolla and anytime I turn on the a/c and make only LEFT turns, it makes a noise like sand or a fizzing sound. Nothing is stuck under the carriage of the car, I checked, as well as under the hood, plus when I turn off the a/c and turn left, no noise. Thank you for any help you can offer.
Awesome as always Mr. Rich. Quick question. Will the compressor clutch cycle on and off if the system is over charged, empty or both?
I've got an 04 Saturn ion tat
Hi Rich, what about the 4 wire pressure sensor how can i test it??
You need to be reading the high and low with a manifold set to get a idea whats going on.
In replacing my radiator on my 96 SL -- I couldn't navigate the radiator back in and "bent" my low charge AC line causing it to leak at the compressor. How difficult is it to replace the AC lines -- andy tips/special tools -- and do you have a video on this topic.. thanks again for the videos you have posted -- they have save me time and aggravation..
