My mechanic says my Toyota highlander expansion valve is located inside the dashboard and to replace it, they need to open the whole dashboard and everything. Is that right, Scotty ?
Recover the refrigerant from the system. Remove the engine air inlet tube and the air distribution duct on vehicles equipped with 3.2/3.5 L engine. Remove one nut to the a/c lines at the expansion valve. Loosen the bolt at the receiver/drier to pivot the lines away from the expansion valve. Plug or cap the open end of the refrigerant lines. Gently pull the a/c line out of the expansion valve. Remove two #30 torx bolts retaining the expansion valve
I've been working on this in my identical Camry for 3 days, Scotty. I finally figured out how you got the Blower Motor out, but now I see that you also took out the ECM and the AC ducts to get the blower motor out. Mentioning that would've been helpful.
@starbucksmunky It sprays liquid refrigerant into the Ac evaporator. As that turns the refrigerant into a gas, this absorbs heat from inside the vehicle and cools you down. When the valve sticks, it doesn't spray correctly, and wham, no cold air anymore. Scotty Kilmer
@jamiedodd1991 There used to be good ways of testing them, when cars had four test ports. Now they only have two test ports, so it's more of a guess. But normally if the valve goes bad, it creates a restriction and the high side pressure goes really high. Scotty
it's better to unbolt the inside bolts to get the expansion valve out, I jusst did one yesterday. But if it only bolts on the outside by the engine, you have to remove those and pull the lines off there

@MrSoundQndn It could be a bad expansion valve or an electronic problem in the dash. when it's acting up, put AC gauges on the the system,and if the pressures are too high, replace the valve. Scotty
@diistriitglow You don't have an expansion valve in that GM, you have an orifice instead, which costs two bucks. A lot easier to change, but that may or may not be your problem. You can't just add refrigerant guessing that's the correct level, it must be done by exact weight by removing all the refrigerant and refilling it with an exact weight using a scale. Scotty
make sure the cooling fans are working on the radiator and condenser. But if they are, I would assume weak compressor that has to spin faster to get coldest
@D12eams Well, there's a lot of levers and switches inside there which control the heat, so pull the radio out and see if you broke or bent something, OR if the radio whacks into a piece so it can't move right now. Scotty
either compressor is shot and not pumping at all, or the expansion valve is stuck wide open and has no effect on system pressure.

@Matthew55904 It's the valve that opens and closes to spray refrigerant inside the evaporator core inside the dash. That makes your air cold by absorbing heat from the cabin. Scotty
celica is inside the dash on the evaporator. but the ford uses an orfiice tube that goes on the high pressure line between the condenser and the evaporator.
@pa28r200t54 Your HVAC system is wearing out, and it now in default mode, only defrost. Start by looking for a vacuum leak under the dash, it's often as simple as a hose falling off. Scotty
well, if it blows cold air until it gets going that fast, often a bad compressor does that. But do check the refrigerant level first and PRAY it's just low on gas.
Man I appreciate you man very straight forward with all your videos. The world needs people that already have money and are willing to pass their knowledge to later generations. I learn so much from you without having to trial and error. Thanks Scotty!
@felipevinalay It could be, but they are hard to check. If the low pressure gets really low and the high pressure gets high, it's often that valve sticking shut. Scotty
blocked orifice tubes would make the high side go sky high, over 300 psi. you have something wrong obviously, but since the swine took all the test ports off decades ago, it's VERY hard to figure out what having only one low side test and one high side. Pretty much guesswork as to what is clogged up because of that. You just have to guess or start taking parts off and seeing which is clogged. good luck.
@StateOfTheArts NO car has room under the hood, and this is easy compared to say, a Jeep, that takes 9 hours or labor to do this job, or a Mercedes, where it could easily cost 2000 dollars to change the exp valve out on. Scotty
@fbruno082 many things can do that, but since it doesn't run, and the pressure it that high, perhaps some nut put too much refrigerant in the system, that's WAAY too high pressure for a system with a compressor that isn't spinning
@docbipe Just fixed the same exact car. It turned out to be a weak AC compressor. Volvo makes REALLY crappy AC systems, waay too complex, and really, how hot does it get in Sweden? Not a land where they care much for AC anyway. Scotty
just being low on refrigerant can do that. My advice is to empty the whole system out, and have a factory load by weight put back in. Pray that fixes it, cause if not, big money repairs on a WRX, the compressors often go out
We mechanics don't normally use that term. But if he's taking about the swirl valve in the engine head, that's a GIANT job requiring pulling the engine apart.
@spelunkerd Well, I can't comment on that because no one uses 12a here in texas, so I have absolutely no experience with it. BUT, 134a works perfectly in any modern vehicle, and it gets damn hot here in Texas. I've got 3 older toyotas I converted to 134a from 12, and they are cold as can be. Scotty
What if your ac is blowing cold and then get hot when you are driving. You off and on again it blows cold and hot. Is it the expansion valve problem too
tons of wiring can be damaged, and if he shut off the ac condenser fan motor, it will cause pressure build up. Start by repairing the burned lines. Pray more damage hasn't occurred.
you may have multiple ac problems. But I would assume you have pressure problems, get a high and low reading of the pressures when idling and when running and e mail me that.
hi scotty just to let you know ive found the problem it was the interior temperature sensor and fan for the climate above the rear view mirror that was causing the problem it was filthy inside and sending wrong information to the computer i took it off cleaned it all out and now its working as it should a simple job that can be easy overlooked... just a suggestion maybe you could put a video on about this as it might help a lot of people thanks for your awesome videos scotty keep them up :)
@kankeralfabet Yes, change the fuel filter out, then pressure test the fuel pump and replace it if the pressure is low. And realize those things have lots of fuel injection problems as they age espeically if it's an old fashioned mechanical fuel injection system. Scotty
Hi again scotty ive replaced the control unit today and it all seems fine apart from one glitch so far it went hot again after i replaced it for a little while then it all went back to normal and stayed that way so you were right Scotty and thanks again for pointing me in the right direction... your videos are awesome... i was desperate to fix this because at the moment in the UK we are in the middle of a 30c and higher heatwave and part of the M25 motorway was closed due to melting recently
hi scotty my problem with my wrx aircon is as follows when i turn my aircon on i can hear hissing from the vents and warm air is coming in i cannot recharge as the pressure drops when i try to fill it. any ideas? many thanks and subscribed :)

you have to disconnect the refrigerant lines under the hood at the firewall, unbolt all the evap case bolts, and wiggle the whole thing out. then it comes apart easily
Nice explanation. I had EV replaced on 2011 F-150, 5.0L V8 engine. Cost $239 for entire process. Symptoms: when I turned on AC, I heard a clatter of noise that came from underneath the dashboard or behind the glove box. The sound was similar to the sound of when you driver over a fairly large branch on the road that beats up underneath your vehicle. Or sounded like you had a big a$$ rat that had gotten beaten by a spinning cog inside your dash panel (behind the glove box). LoL Funny, (I liked that one.) Also, the AC blew extremely hot air. almost scalding air into the cab. hwew, that scared the heck out of me. I knew that meant (money to be $pent). Anyways, after seeing all the steps to access the EV, I now understand the high cost to repair. Thanks again. Good video. Thumbs up.
Love your videos but C'mon man, if I seen my apprentice pouring oil into oil lids resting on the customers front seat he'd get a swift left jab to the right eye socket :)
Where's the expansion valve on a 2004 Lexus GX470? Is it similar to the Toyota (behind the glove box requiring it's removal together with the blower motor?)
Thanks again Scotty one more thing i noticed last night if i turn off the air con it still blows hot even when the climate control is on its lowest setting... now when i first put on the air con.. sometimes the light goes on then it kicks off within about a minute i then put it back on then it goes hot. now this is something when everything is working normal there,s not a lot of heat even when its set on high so im thinking could it be the control on the dash that's at fault? or the valve
hi scotty, I have 2000 Altima, and the ac work for few minutes and them hot air come out, I turn off for five minute and when I turn it on start working again, do you thing is the expansion valve. how can I check the valve?
Scotty, What is the trick to getting the bottom of the "evoporator cover" off? I have not unbolted the lines at the firewall, under the hood, but I have removed a whole lot of screws from behind the glove box.
you are the MAN!! Quick question. I feel the low side cold under the hood but blows hot air inside. This is due to a bad expansion valve? and before i replace the valve, i would think to bleed out all of the refrigerant correct?
Is it necessary to evacuate the AC lines or can you perform this job without that step? Or when you remove the expansion valve will pressure suddenly start escaping?
Hi Scotty, I'm not sure what year your Camry was that you replaced the expansion valve on, but I have a 1994 Camry with the V6 and I could not for the life of me figure out how to get the blower motor out. We took off all the bolts, and could move it around a little, but it would not come out. Is there a special trick to this you made it seem so easy. Thank you
you can't flush a system with an expansion valve in it, it can ruin the valve. The valve has to be removed to flush the system correctly. I would not flush it at all if you're leaving the valve in, or just flush the part the valve is not in.
I just took the entire dash out of the van and the HVAC housing to replace the evaporator. It leaked through the valve inside and had to be replace. The job is much bigger than I though. Anyway, I have a question... Do I need to replace the Ring around the evaporator and condensor behind the hood after I pulled the housing out and do I need to replace the heater core ring and temperature sensor on evaporator as well? Please let me know soon. Thanks. :-)
Wow! That job is very easy to do on a Camry. Even can get the evaporator core out with ease. My 00 Taurus requires dashboard removal for evaporator core access. I dread that day! Helped a friend with his 2002...good learning experience.

Hi Scotty thank you just one more thing on this when the air con is off and the climate control is set to its lowest setting the air remains hot and when this happens any setting 16c up to 25c it just stays the same..now sometimes everything works as normal,,then you hear the fan change sound as if the flaps are moving it goes back to hot and stays there today i removed the control unit and put it back in when i did i could hear the flaps resetting themselves so could i be looking at a bad CU
hi scotty got a problem on my 2003 toyota prado. the ac compressor went out so i took it to a mechanic and changed the compressor with a new OEM part, while i was there i went and changed the evaporator and condenser too. so i got rid of all leaks and changed o rings and hoses and charged it up. Now the ac blows cool but not cold enough the way i remember. so checked it with another mechanic with tools and he said the compressor is not pumping enough pressure nd needs to be replaced.

Hi I have a 2001 CRV that had a burn Valve according to Mechanic that did the check up I have a question what exactly is the Burn Valve? What cost to Burn Valve? What is the cheap way to fix it. Please Advise
2005 Chevy Equinox warm air at sitting idling I changed the expansion valve and still warm air , there is no Orifice tube for this vehicle.... can you help it gets cold only when I rev the engine to 2400 rpm
I also can't get expansion valve off it's all lose including the valve, but won't come out the housing, should I also remove the evaporator, from inside? if so it will be a big job
albertfroz If you have ALL the valve bolts taken off, the valve often is pretty stuck, I pry em off with a thin putty knife to get em going, then twist em off
Hello, I wanted to ask a question about a 2010 Mazda CR 7 - the new compressor, Dry and condenser have already been changed and they have told me that the expansion valve needs to be changed but that it is a job where the slate has to be lowered - without However, in your video I see that it is not necessary - could you please explain it to me - Thank you

Yo! Number 10... Where'd ya get it and what'd ya pay? Dammit, I need some.
My mechanic says my Toyota highlander expansion valve is located inside the dashboard and to replace it, they need to open the whole dashboard and everything. Is that right, Scotty ?
Scotty, my friend installed a rear expansion valve on the position a front EV goes, what if any problems will this cause
Recover the refrigerant from the system.
Remove the engine air inlet tube and the air distribution duct on vehicles equipped with 3.2/3.5 L engine.
Remove one nut to the a/c lines at the expansion valve.
Loosen the bolt at the receiver/drier to pivot the lines away from the expansion valve.
Plug or cap the open end of the refrigerant lines.
Gently pull the a/c line out of the expansion valve.
Remove two #30 torx bolts retaining the expansion valve
Scotty Kilmer I got a 2010 Lincoln mks ecoboost engine 3.5L do you know where the expansion value locate? 😎😎😎😊😊
I've been working on this in my identical Camry for 3 days, Scotty. I finally figured out how you got the Blower Motor out, but now I see that you also took out the ECM and the AC ducts to get the blower motor out. Mentioning that would've been helpful.

Place expansion valve on seat upholstery and pour oil over valve...
Classic Scotty at work here!
Loving it.
it's better to unbolt the inside bolts to get the expansion valve out, I jusst did one yesterday. But if it only bolts on the outside by the engine, you have to remove those and pull the lines off there

@MrSoundQndn It could be a bad expansion valve or an electronic problem in the dash. when it's acting up, put AC gauges on the the system,and if the pressures are too high, replace the valve. Scotty
if it's a rebuilt oem comp, they often are bad. But I would have changed the expansion valve during the first job, do that if it hasn't been done yet
@diistriitglow You don't have an expansion valve in that GM, you have an orifice instead, which costs two bucks. A lot easier to change, but that may or may not be your problem. You can't just add refrigerant guessing that's the correct level, it must be done by exact weight by removing all the refrigerant and refilling it with an exact weight using a scale. Scotty
make sure the cooling fans are working on the radiator and condenser. But if they are, I would assume weak compressor that has to spin faster to get coldest

@D12eams Well, there's a lot of levers and switches inside there which control the heat, so pull the radio out and see if you broke or bent something, OR if the radio whacks into a piece so it can't move right now. Scotty
na, just parts of the passenger side, I find bending some of the metal supports gets it out easier, then you bend em back when done

@Matthew55904 It's the valve that opens and closes to spray refrigerant inside the evaporator core inside the dash. That makes your air cold by absorbing heat from the cabin. Scotty
@mazdarx7head yep, the evaporator is clogged up. Often you can blow up through the drain hose to clear it out. Scotty
celica is inside the dash on the evaporator. but the ford uses an orfiice tube that goes on the high pressure line between the condenser and the evaporator.
@pa28r200t54 Your HVAC system is wearing out, and it now in default mode, only defrost. Start by looking for a vacuum leak under the dash, it's often as simple as a hose falling off. Scotty
well, if it blows cold air until it gets going that fast, often a bad compressor does that. But do check the refrigerant level first and PRAY it's just low on gas.

@felipevinalay It could be, but they are hard to check. If the low pressure gets really low and the high pressure gets high, it's often that valve sticking shut. Scotty
blocked orifice tubes would make the high side go sky high, over 300 psi. you have something wrong obviously, but since the swine took all the test ports off decades ago, it's VERY hard to figure out what having only one low side test and one high side.

@StateOfTheArts NO car has room under the hood, and this is easy compared to say, a Jeep, that takes 9 hours or labor to do this job, or a Mercedes, where it could easily cost 2000 dollars to change the exp valve out on. Scotty
Great video- you do a marvelous job being enthusiastic and editing well.
hello
@fbruno082 many things can do that, but since it doesn't run, and the pressure it that high, perhaps some nut put too much refrigerant in the system, that's WAAY too high pressure for a system with a compressor that isn't spinning
I like how he fix everything in 4 minutes.
Michael Kokoschka lol
Michael Kokoschka well he dose and he doesn't that is elapsed time it may take longer but of only car problems could be solved in 4 minutes
lmfao right
He edits out all of the cursing.
@docbipe Just fixed the same exact car. It turned out to be a weak AC compressor. Volvo makes REALLY crappy AC systems, waay too complex, and really, how hot does it get in Sweden? Not a land where they care much for AC anyway. Scotty

Hi how you determine the expansion valve is faulty
Having a engaged compressor and clutch but no cold air from A/C
@@some_thing6717 my issue ended up being a burnt cooling fan fuse, same issues as you described
last one I did had an expansion valve on the firewall you can see under the hood.
glove box area. dryer is under the hood near the radiator.
@axlrosesslash It could be, that's pretty typical. it's the first thing I'd change. Scotty
could be tons of things, but I'd check for leaks first if you had to fill it two months ago
it could be the orifice tube, that's why GMs use. But often it's a control issue, see my new video "fixing Car AC that blows Hot"
What if your ac is blowing cold and then get hot when you are driving. You off and on again it blows cold and hot. Is it the expansion valve problem too
Like honestly, your like a cool mechanic version of bill nye the science guy, and both will forever be in my memories as good educational videos.
you only add if any was lost, so it's pretty much just guesswork. In this place it was not working, but didn't leak, so I added no oil
tons of wiring can be damaged, and if he shut off the ac condenser fan motor, it will cause pressure build up. Start by repairing the burned lines. Pray more damage hasn't occurred.
you may have multiple ac problems. But I would assume you have pressure problems, get a high and low reading of the pressures when idling and when running and e mail me that.
@sloflo1 You have a restriction in your system, most likely a bad expansion valve like in this video. Scotty
hi scotty
just to let you know ive found the problem it was the interior temperature sensor and fan for the climate above the rear view mirror that was causing the problem it was filthy inside and sending wrong information to the computer i took it off cleaned it all out and now its working as it should a simple job that can be easy overlooked... just a suggestion maybe you could put a video on about this as it might help a lot of people thanks for your awesome videos scotty keep them up :)
@lvlik9 It's just a sealer, you really can't buy it. Just get some small pipe insulation from a hardware store and wrap it. Scotty
Great video......but how do you know if the expansion valve has gone bad, is there a way to test it?
@kankeralfabet Yes, change the fuel filter out, then pressure test the fuel pump and replace it if the pressure is low. And realize those things have lots of fuel injection problems as they age espeically if it's an old fashioned mechanical fuel injection system. Scotty
Hi again scotty ive replaced the control unit today and it all seems fine apart from one glitch so far it went hot again after i replaced it for a little while then it all went back to normal and stayed that way so you were right Scotty and thanks again for pointing me in the right direction... your videos are awesome... i was desperate to fix this because at the moment in the UK we are in the middle of a 30c and higher heatwave and part of the M25 motorway was closed due to melting recently
yes, often a bad control unit will do that
could be valve or low on refrigerant. Have a pro check it first. The exp valve is pretty much the same as this video
Yep, I finally got it out. I went ahead and unbolted the lines at the firewall, under the hood, like you showed in your video. Thanks. Go Astros.
Scotty you rock! Doing on conversion on a 1993 Camry and trying to figure out where the expansion valve is. Your video is spot on!
After suffering bad AC for 2 year, until I saw your 4:00 minutes video, I cried, hardly.
yes, you can, but evacuating it for an hour or so will boil all the humidity out.
could be both, but try the expansion valve FIRST as that may fix it all
they do sometimes stick, just keep wiglling and pray. If it breaks, you'll need new expensive lines, or used junkyard ones.
they don't have expansion valves, they have orifice tubes. it or something else is clogged up., Or you're just low on refrigerant, check that first.
yes, that is common, also check the ac clutch magnetic relay, they can do that too
I always find Scotty's vedios to be helpful first before I look at another mechanic vedio 👍
inside the dash, pretty similar to this one.
Scotty Kilmer for president
80 percent load you put in. I would change the hoses and drier on that old thing too.
worth a shot, could be that, and yes, you have to evacuate the system out to replace it.
hi scotty my problem with my wrx aircon is as follows
when i turn my aircon on i can hear hissing from the vents and warm air is coming in i cannot recharge as the pressure drops when i try to fill it.

Don't you also have to add some lubricant to the system, or did you just add enough when you lubricated the one rings?
Thanks for your response. If the fan is running okay should I start with the expansion valve, or just bite the bullet and put a new compressor in?
Love your videos but C'mon man, if I seen my apprentice pouring oil into oil lids resting on the customers front seat he'd get a swift left jab to the right eye socket :)

Yeah but he made up for it at the end of the video when he changed sides to the camera just to say bye
Well good thing it's his car

Obviously a beater probably his
yes,
Where's the expansion valve on a 2004 Lexus GX470? Is it similar to the Toyota (behind the glove box requiring it's removal together with the blower motor?)
Thanks again Scotty one more thing i noticed last night if i turn off the air con it still blows hot even when the climate control is on its lowest setting... now when i first put on the air con.. sometimes the light goes on then it kicks off within about a minute i then put it back on then it goes hot. now this is something when everything is working normal there,s not a lot of heat even when its set on high so im thinking could it be the control on the dash that's at fault? or the valve
i would change accumulator and also flush out the EVAP AND CONDENSER,
yes, expansion valves can go bad and do that. A pressure test by any decent mechanic would figure that out though
My mechanic says my car passed the pressure test, but I got a new compressor and he suggested a new expansion valve. Is this a good suggestion?
hi scotty, I have 2000 Altima, and the ac work for few minutes and them hot air come out, I turn off for five minute and when I turn it on start working again, do you thing is the expansion valve. how can I check the valve?
it's actually a bit easier than this one, you remove the evaporator case, split it in half, and the valve is inside
Scotty, What is the trick to getting the bottom of the "evoporator cover" off? I have not unbolted the lines at the firewall, under the hood, but I have removed a whole lot of screws from behind the glove box.
I would definitely change out the expasnion valve myself, sitting that long with air in it
Scotty Kilmer I have a 2006 scion xb ac button light turns on but no cold air at all
In my 2011 Camry you can do this from under the hood, found out when replacing compressor, condenser, etc... Love your videos!
you are the MAN!! Quick question. I feel the low side cold under the hood but blows hot air inside. This is due to a bad expansion valve? and before i replace the valve, i would think to bleed out all of the refrigerant correct?
Do you HAVE to empty out the refrigerant before doing this? I recharged my AC right before realizing the expansion valve needed replacing.
Is it necessary to evacuate the AC lines or can you perform this job without that step? Or when you remove the expansion valve will pressure suddenly start escaping?
Hi Scotty,
I'm not sure what year your Camry was that you replaced the expansion valve on, but I have a 1994 Camry with the V6 and I could not for the life of me figure out how to get the blower motor out. We took off all the bolts, and could move it around a little, but it would not come out. Is there a special trick to this you made it seem so easy.
Thank you
you can't flush a system with an expansion valve in it, it can ruin the valve. The valve has to be removed to flush the system correctly. I would not flush it at all if you're leaving the valve in, or just flush the part the valve is not in.
I just took the entire dash out of the van and the HVAC housing to replace the evaporator. It leaked through the valve inside and had to be replace. The job is much bigger than I though. Anyway, I have a question... Do I need to replace the Ring around the evaporator and condensor behind the hood after I pulled the housing out and do I need to replace the heater core ring and temperature sensor on evaporator as well? Please let me know soon. Thanks. :-)
Wow! That job is very easy to do on a Camry. Even can get the evaporator core out with ease. My 00 Taurus requires dashboard removal for evaporator core access. I dread that day! Helped a friend with his 2002...good learning experience.
that older one is a bit easier than this one. If you like my car help, be sure to watch my live car talk show every saturday morning at 10 AM CST on google events.

Hi Scotty thank you just one more thing on this when the air con is off and the climate control is set to its lowest setting the air remains hot and when this happens any setting 16c up to 25c it just stays the same..now sometimes everything works as normal,,then you hear the fan change sound as if the flaps are moving it goes back to hot and stays there today i removed the control unit and put it back in when i did i could hear the flaps resetting themselves so could i be looking at a bad CU
How you have a video on how to replace one on a 94 celica????
hi scotty got a problem on my 2003 toyota prado. the ac compressor went out so i took it to a mechanic and changed the compressor with a new OEM part, while i was there i went and changed the evaporator and condenser too. so i got rid of all leaks and changed o rings and hoses and charged it up. Now the ac blows cool but not cold enough the way i remember. so checked it with another mechanic with tools and he said the compressor is not pumping enough pressure nd needs to be replaced.

Hi I have a 2001 CRV that had a burn Valve according to Mechanic that did the check up
I have a question what exactly is the Burn Valve? What cost to Burn Valve? What is the cheap way to fix it. Please Advise
2005 Chevy Equinox warm air at sitting idling I changed the expansion valve and still warm air , there is no Orifice tube for this vehicle.... can you help it gets cold only when I rev the engine to 2400 rpm
Hi Thanks for the video, can I use engine oil for to O rings? is it similar to do with 2004 accord 2.4 I vtec?
I also can't get expansion valve off it's all lose including the valve, but won't come out the housing, should I also remove the evaporator, from inside? if so it will be a big job

If you have ALL the valve bolts taken off, the valve often is pretty stuck, I pry em off with a thin putty knife to get em going, then twist em off
Scotty Kilmer Ok I will try it thanks
Scotty sometimes my ac blows cold and sometimes it doesn't. Do you think it may be a expansion valve. 02 honda civic ex
Hello, I wanted to ask a question about a 2010 Mazda CR 7 - the new compressor, Dry and condenser have already been changed and they have told me that the expansion valve needs to be changed but that it is a job where the slate has to be lowered - without However, in your video I see that it is not necessary - could you please explain it to me - Thank you
