- Here is a simple guide that should be able to help you with some of the most common basic procedures for diagnosing your Air Conditioner and heater that is no longer blowing air.
These steps can be taken in different orders to help determine what your issue may be. The specific steps in this video are not always the exact same for every vehicle but the process of elimination is very similar in all cases. - แนวปฏิบัติและการใช้ชีวิต
Thank you for this analytical approach. It allowed me to methodically rule out everything down to the blend door actuator - which I replaced today with the help of another TH-camr. Now I have heat!
Sir, Today I replaced the resistor plate, very helpful to cut to fit the part. I love my old Express van, I will not buy new SUV
Keep up your good work
Excellent tip. I followed your guidance on my 2004 Express and rebooked the loose wires (black and brown) and it worked perfectly. Thank you
@Peter Han 👍👍👍
Thank you so much for the indepth detail.......AMAZING JOB...................peace
Great video, and I found it just in time. My guess is it's the blower, but I'm going to test/ check everything you showed us so I get all the parts I need. Thank you for the video!
If you break off or cut the plastic prongs and push the resistor in a little it will slid right in. No need to cut the housing.
Thank you for sharing.
Excellent video with steps on diagnosing, thank you, well done!
Awesome, saved me a pretty penny from not taking van to Dealership. Easy to follow and do
Thank you for the feedback. 😁
Thank you for all your help. Great video!
Thank you for share i was trying to find the exact replasment. you save my day.
Same exact van. Same exact problem. Same exact replacement resistor difference! Perfect! Thanks
Glad it worked 🤙🏼
This is a great video, I have 2004 Chevy Express 1500 Base V6, very similar issue I am having now, the dealerships is so busy now and
I believe I can replace if I get the parts. Thanks for informing me about the resistor, it's discontinued. I am going to replace the fuses,
I have the new resistor which I have to modify like you did. I hope that works if not I will get a new blower. Awesome video!
Many Thanks to you for this complete and logical diagnosis and instructions on R&R. I especially appreciate your heads-up on the new resistor necessary modifications. I now have a good grasp of every step needed, as well as a ballpark on time & costs, I like my 2001 Texas Van, and I've liked and subscribed to your channel. Greatly Appreciated !! 💪🏼👍🏻
Thanks for you time and patience, also very good explanation, you are the best, thanks for sharing

Thanks for sharing 👍
Your very welcome. Cheers
Helpful thank you
Good video. Thank you very much. It's going to come in handy down the road. 👍👍🙂🇨🇦
Cheers!
Back when I was younger and I had trouble with heater motors, he always used to get out and hit it with their wrench and it would turn back on because it had a flat spot. It would work for so long but then you had to replace it.
@@ipaddlemyowncanoe.7441 definitely had to do that a bunch, I can picture it now :-) driving down the road trying to find some thing a long enough to hit underneath the dash to clear up my windows 😬😂
Idid it! My blower didn't come with a gasket, and the old one didn't have one. I tried to wiggle the resistor in. Ended up bending the posts connecting the resistors. I had to cut the plastic like you did. The bottom of the slot was warped, so I cut some foam off the old resistor. I think it cost about $138.
I forgot to mention that it was around 17⁰F and sunny lol. First time living in snow country. I used to wear shorts and a tank top year round in Sacramento County! Even when I walked the dogs at 6 or 7am in the winter. I would wear a jacket maybe twice a year.
Thank u bosss for all
Your welcome!
Thanks Mr
@SALVATORE Lopez your very welcome 👍
Txs hope i can fix mine
Thank ya
Great video,but turn up the volume bro.
Thank you for tis video. It is in depth without any excess verbiage. I have a 2011 Express 2500 and the fan works on 1 and 3, but 2 and 4 just recently cut out on me. I suspect it's the relay. Should I replace the fan also? What are your thoughts?
I personally would replace both just to save time, but if your close to a part store and time isn’t a factor I would then start with the relay.
Good shit my boi
Gracias Ati vídeo arregle mi Ben.👍👍👍👍👍😎😎😎

hi, does someone or you have an idea why my van (same model) only blows air out of the front valves when it is "high"? Resistor and vacuum already checked.
My resistor plug melted a wire but easy to get a new one a splice it onto the old wire harnesses
I'm trying to fix this for my 2003 Express. The blower is still not working. What's confusing me is that I have 12 volts from the resistor connector, but zero voltage out of the blower connector when it's all assembled even though I have a new resistor. I performed this test with the old resistor in place and had the same results.This is why I replaced it.
When I check the resistor connector, I place the multi meter prongs in the orange wire and black wire and have 12.7 volts. I figured that I should be using the prongs on the red and black wire to get a reading, but it does not get a reading. What am I doing wrong ?
Have you by chance been able to force the blower motor in the running position? Does tapping on the blower motor itself cause the motor to slightly turn on? I’m pretty sure that the blower motors on these vehicles have a separate fuse.
👍👍
Good job. I have a 2000 cheevy express and the heat just work on hight speed. I guess I will need the resistor.
Some how the rear heater do not work. Any idea what would be ?
First thing I would check is the fuses/relay, then I would check the fan switch followed by checking out the blower motor. Do you have a separate blower motor for the rear heater?
same thing with me. I have 2001 Chevy express. new AC compressor, fuses fine. only ran on high for ac and heat for 3 years.. recently it won't blow at all.feeling the slightest air at accelerating hwy speeds.. but I see compressor clicking on and freezing.
so I will be doing this this coming weekend
Hi I just changed the sensor fan but when I go turn on the fan The fuse is burning what happens
@Sundu Marian, was the fuse blown before you replaced the sensor? I would double check your sensor to make sure none of the contacts are touching anything that they’re not supposed to. Does the fuse blow immediately after turning the fan on?
Hi, great video, I have a 2013 Chevrolet Express 2500 and the heater blows when set to Low and High, but not in the middle. Any suggestions? I took it to a shop and they want over $2,500.00 to replace the blower motor and resistor. It seems expensive.
I had same issue repo aced resistor Assy and wiring for resistor was melted. Not hard to do and no where near $2500
So what could it be if the blower motor is getting power but it's still not coming on? Not to mention that cluster that you said was wires on my van is all vacuum lines because most Chevy's all the controls are ran by vacuum
@Johnathan Bachman that sounds like it would be a bad blower motor. I must have mistakenly said wires when they are as you mentioned vacuum lines.
Do you know what that plug under the passengers side dash is for? 2:20 in your video...
I believe that plug actually has a few vacuum lines attached to it which controls the temperatures of the climate control. They originally looked like electrical wires but one I unhooked a few of them I quickly realized they were not.
My friend Where is the link to be able to buy the parts because I have the same problem?
@Alberto Licona if you share the year, make, model and the engine size I could locate your parts for you.
Hey, I have a 2010 GMC Savannah School bus. Same issue as you, I can hear it changing with the settings dial but nothing is coming out. I tested the two terminals on the resistor like you did and it was reading 0.07 on 20v setting. This was with the key turned and heat dial on. My question is, how do you know it’s not the wiring harness that’s bad? Nothing looks burnt on the terminals but when I put the multimeter in the harness nothing is reading (not sure if that’s how you test it though)
@Zach Teschendorf thank you for reaching out, have any of the fuses blown in the circuit? Also have you tested the power going to the blower motor as well? When testing the voltage definitely try multiple different grounded locations to get the most accurate reading.
@@TweekerDan1984 Let me correct myself, the reading was .82 when test the power from the resistor. Do you know exactly what fuses and relays go to the blower? All I saw in the fuse box was a front blower 40a Jcase fuse which was actually blown. I replaced and still nothing.
After searching I couldn’t find a relay in any of the diagrams. It does look like there may be additional HVAC fuses that you could test as your vehicle may have two fuse panels. Do you know if you have 12v at the blower motor power inlet harness? That would help narrow it down. The resistors are know to fail without signs of damage.
@Zach Teschendorf If you would like me to send photos of the panels I’m looking at for your vehicle you are welcome to reach out to me via instagram @TweekerDan1984
Does the fan work straight from the resistor???
I had someone replace both but fan still not working
It works with straight 12v and there is electricity on the resistor as well as signal
Have you tested or checked the fuse or relay?
can a bad blower motor cause my van to over heat up?? I already replaced the water pump, radiator, thermostat, and temp sensor but the temp gauge slowly goes up but stops at almost red. but once I turn on the heater on it jumps up to hot then my check gauges light turna on.
Are your cooking fans working?
@Sinister Mind if you have replaced those items and your coolant has remained full then it is possible for a clog or air picked in the cooling system. Are you heater hoses getting hot and pressurizing once you vehicle gets warmed up?
@@TweekerDan1984 my van only has 1 fan and its attached to the fan clutch.
@@TweekerDan1984 how could I remove the air in the cooling system?? I also removed both hoses on the heating core and ran water through both inlet and outlet and water did come out on both ends.
My Astro van 4.3L only blows cold air.
There is a regulator on your blower motor air box that commonly burns up. I had a gmc safari with the same motor and set up.
I wonder why you replaced the resistor. It seems that if you tested the motor wire for voltage first that all the other items could have been unnecessary. IF there was no voltage then work your way back by going upstream - resistor, switch, fuse.
@cliffbadger1 good day! It has been a while but I believe I replaced the resistor because not of fan speeds were functioned properly. We encounter these issues 100s of times a year and the video was intended for a DIYer without overwhelming them. The idea is to keep the process less complicating and to save people their time and money.
Hey brother so I watched you clip here and when I removed the resister the is one of the connections that is melted. It is the C terminal. Now I am trying to replace that harness so it will be good for the new resister but can't find where it goes. Can you help? Also do you know why this must have happened. I can tell you that the one coming out is a newer one and already has the housing cut to fit. And the terminal that is burnt is a thicker black wire
Replaced mine that was also burnt. Had to just cut it off of wiring harness and reconnect new plug to harness by soldering with heat shrink or insulated crimp on terminals. Not hard at all I left extra cable so not to cause issue if have to do again.
@@darinwells5448 thanks man keep up the good flow of info
Will it work on a 2010 Express van
I believe it would be the same.
Mine is not the fuse, it's not the resistor, and it's not the blower everything is brand new what else could it be? Debating on grabbing power off the controls and wiring each fan setting to a switch through some dry contacts and some relays. The only way a residential HVAC technician would want to repair it
Have you tested the dash switch? If so, do you have 12 volts coming into the switch? Sometimes the switch itself will fail. If you have power to the switch I would move through to test other components. I would also be sure to check for good grounds as they are most commonly overlooked. There is always the possibility of new parts failing quickly or even right out of the box.
My blower motor goes by itself > even if the van is not running and no key > do you no what can make it go on and off on its own. Thanks.
Sounds like the resistor or the fan motor, try tapping on the fan when the motor is not working, also I would inspect the wiring for loose connections or damaged wiring.
I’m sure you’ve solved your problem by now.. but FYI for anyone else experiencing this problem- it IS caused by the resistor. Specifically, the internal relay is stuck in the “HIGH” position which draws off 30amp fuse and is hot at all times; it is not controlled by ignition switch like the 25amp fuse. You can find more detailed explanation at 3:50 of this video..

Mines making a very loud noise when turned on.
Is it a screeching loud or a growling loud? If so it may be the motor bearings failing. You would then need a new blower motor.
I’ve checked all of those still not blowing heat
Are all of the positions working when using the knob for the blower speed? If everything is functioning properly and your confident that all of the tubes and wiring correct then you may want to start looking toward the coolant system. First thing I would check here is to see if your coolant is completely full. Not just in the reservoir, but also by removing the radiator cap with the vehicles cold and making sure the coolant is filled all the way up to the top of the radiator.
Help me please if you think samthin
Hi i gest chengi ol this staf bat hi born autmai fiuss fast
No links, 😪
I’ll look into finding new links, it seems the links I had expired.

Thanks for this. I guess I can put my sledge hammer away now... 🤏 close. It's not easy driving with a propane heater bungeed to the dash; facing the windshield.
😂🤣
Thank you
