My heat and ac was only working on high for a while. It finally decided to go right as I was pulling up to the hospital to pick up my new born son. Saw this video and was able to fix my heat quickly. Thank you for the video
The 3rd speed of the blower switch on my '06 GMC K1500 has not worked for a couple of months and last week it completely quit. I'm so glad that I googled "blower switch" and came upon your video before I wasted my small pension on a dealer only blower control switch. I'll now order the resistor and save your video for my husband's benefit. I might even install it myself. Thank you so much and have a great week! Andrea
Dear Mike Green, I am no the type of person who does a lot of repairs on his vehicles. Praise the Lord, with your video, it gave me the confidence to do it. Everything is working ok now and I really Praise the Lord for you and your video. Thank you.
+Walter Erhart Thank you for the positive feedback. We really appreciate it! If you have a minute, drop us a review on our Facebook page to let other people know about your experience with us. Here's a link: facebook.com/1AAuto/reviews/
Just followed your video and replace the one in my wife's truck. It was right on the money. Everything is back to working again. You guys are definitely a blessing and a Godsend. Thank you.
JUST FINISHED THE JOB AND WITHOUT YOUR VIDEO POST I AM SURE IT WOULD NOT HAVE GONE AS WELL. MANY BLOGS OUT ON HOW TO DO THIS JOB BUT YOUR VIDEO IS A LIFE SAVER. THANK YOU VERY MUCH FOR YOUR WORK.
Thank you!! My suburban's ac was only working on high speed, I watched your video, head to auto store and replaced it. Saved me a trip to the shop and $$$$

1A Auto's youtube channel is a master class for diy auto repair.
Even when the repair is above my pay grade, I come away with an understanding of the process and am able to more accurately convey the problem to my mechanic.
Thanks gentlemen!
I bought the part from 1AAuto , watched the youtube video, & 30 minutes later it was fixed. My fan had low air output on 1-4. And #5 blew ( or didn't blow) whenever it felt like. Now everything works great! Thanks!!!
1A Auto is my GO-To instruction guide for tricky repairs. Always on point, professional, succinct! Great Job guys!
Replacement worked exactly as described. My '01 Silverado has only had fan speed "5" working for years. Had an auto electrics specialist tell me to "just get a new a/c control panel. About $100 for parts, plus labor." Your video has me up and running for under $25. If I wasn't hitting the hiway tomorrow, I would have bought my resistor from you. You've earned my respect, and I'll make sure I check you first next time I'm diagnosing a problem with my truck. Again, many thanks!!
+Rex Anderson Thank you for your order. If you would like to leave us a review on Google it would be greatly appreciated. Here is a link to our reviews section. Have a great day! goo.gl/i5JFNY
Used this video to work on a 2006 Chevy Tahoe Z71.
only real difference was that 2 bolts removed the cover 90% and the resistor was right up front to the right. no other screws or bolts removed. Do be sure when you order your part, know what hole line up yours takes. i got mine for $25 but holes were a little off. For $55 i could get same part with correct holes. I secured it and it works just fine.
Thanks for the great video!!!
Thank you for the help, The 3 levels of speeds of the fan wasn't a concern of mine then #4 and #5 acted up and were not working all the time and thought this could be a costly repair to my truck. The truck has 241,000 miles on it and sometimes wonder if it's worth repairing. When I pulled up this video it showed me exactly what was happening to the truck and with a little help from this video I was able to repair this at a low cost!! The tutorial was very precise and helpful to make this a quick fix. Thanks again and I have used this site and will continue to use this for future repairs!!
Thanks for watching. Have a great day! 1aauto.com 888-844-3393
THANK YOU so much for posting step-by-step DIY repair videos for us novices. With winter about here, the heater fan in my 2005 Sierra 1500 (with 88k miles) quit altogether [after the 5th speed setting quit weeks ago] so, I have a feeling, it's the Fan Speed Control Blower Motor Resistor .
In Oct. '11, when the Check Engine icon lit up on the dashboard, my Abeloff GMC Dealership charged me $88. to find out the EVAP is leaking and the heater blower speed 5 quit.
Thanks. This helped me save $260. Part cost me $40. The dealer wanted $300. This took like 30 mins to install. The most difficult part was getting the cover back on.
This video was awesome! I watched it once, bought the part (it arrived 2 days later.-Thank You) and did the install this morning on my wifes 2002 tahoe. She will be pleasantly surprised on her ride to work tomorrow. thanks again.
+nicksdad nicksdad We love to hear that our videos are helping people get the repair done! That's our main goal. Great work, and thanks for checking us out.

I have a 2001 yukon xl that was only working on stage 5. I ordered the part from 1aauto and followed this video and minus one difference in screws that held the decorative cover on, it was perfect. Thanks so much! BTW.. I found that a 9/32 would work in place of the 7mm socket as I didn't have one. I also found the deep socket to be of great help in the "hidden" bolt that in my case, was also behind the center console tape player and no fun to get at.
After watching some videos on here I tackled mine it was the plug going to the blower on a 2005 Silverado! Check it your self & save a ton of money in shop time and on parts, thank you every one for your videos regarding this issue!
+Jack Daniels Sometimes the plugs can melt. If any of our viewers needs to replace their blower motor resistor, we carry the part shown in this video on our website.

Thank you for the comprehensive video! This looks very helpful and actually makes it look like this could be easy enough for us to do ourselves instead of taking it to the dealer. We've lost our bottom four speeds on our 2001 GMC sierra z71 blower. Would love to have this be a relatively inexpensive repair!!

Replace both; the resistor block and the connector coming into that block (5? or 7) wires. They both overheat and melt the plastic around the pins, causing them to loose contact.
Great video, thanks for taking the time!
Thanks alot for the help! The resistor I took off was the 2 hole and it didn’t match to so the previous owner screwed the driver side screw in first and then used a 1.5” ish wood screw to hold the other side in. Oh well! Go with the flow! It works! Very good directions!

@organicmaniac You're welcome. We carry the blower motor resistors on our website for your 99-06 Chevy Silverado. Hope this helps, have a great day!
Usually that's the sign of a bad blower motor resistor. We carry them on our website 1aauto.com 888-844-3393 Hope this helps you out.
1A Auto Thank you so much for making this video, my fan just stop working on my truck, and I'm going to do what you showed on this video. And if I need parts, I will get it from 1A Auto. Thank you
+martin rodriguez Thank you for watching. Please let us know how the repair comes out! 1aauto.com 888-844-3393
Great video ....save me a bunch of time instead of searching thru the manual .....
We're glad the video helped you out. Thanks for watching. 1aauto.com 866-403-3393
Used this info to change the resistor in my 2010 Silverado. Slightly different but basically the same. Great help. Thanks!
Thanks a lot! Second time one of your videos have helped me by one, saving me some money, and two, fixing my car!
@caltex86 If you click on the link in the video, it will take you to the proper blower motor resistor.
Normally an issue like that would be the resistor but the best bet would be to check the resistor to see what sort of voltage is going to the unit at the different blower motor settings to check and make sure that is the issue.
You may want to check the transfer case shift motor, and also the switch to see if they're fuctioning properly.
@22matthewlewis That would either be a door actuator issue, or even a loose, disconnected or broke vacuum line. I would check all of the vacuum lines first to see if any have come disconnected.
Great video! Helped me a lot. Not to tell you what to do but it would also be a good idea to clean the duct and replace the cabin air filer too.
@Nighthawke70 I would check with making sure the fuse is good, and that there's also power to the blower motor resistor and also the blower motor. If you noticed that the speeds began to not work on the AC control that's typically the sign of a resistor going bad. If it just stopped blowing air all together than the blower motor could be the culprit.
Thanks! This helped me replace mine on a nice warm 100 degree day in Ga.
Thanks for the video. I was able to change my resistor (2005 Yukon) in less than 1 hour. I didn't/couldn't have to take out the center screw on the outer casing. I took out all but and pulled down the plastic. Just remember the 2005 Yukon has the 4 hole version of the resistor (costs $25 more).
@TheMan16111 It sounds like the blower motor resistor may have gone bad. Usually when they go bad you start to lose the lower speed settings. Hope this helps you out.
@txrelichunter Please use the link in the description and check our website, Thank You!
It sounds like when the repair was made something was hooked up backwards. You may want to re-check the connections and possibly try to reverse this to see if it will solve the situation that you are having.
Going to be doing this over the Christmas Weekend. Thanks for the awesome video.
+MrD Poling Thanks for watching. We carry the replacement blower motor resistor shown in this video on our website. We also offer free shipping on all orders in the lower 48 states.

Usually when the blower motor resistor fails, you'll typically start to lose the lower speeds. Here's a link to them on our website if you would like to take a look at them. 1aauto.com/1A/BlowerMotorResistor/Chevy/Silverado1500/-/-/1999?ATony
Thank you!!! This video help me replace this part on my 03 suburban. saved me tons of money
@quadty11 thanks for the comment and remember to check out 1A Auto dot com for your parts needs.
@lillola06 If everything works and it just blows cool air. You may want to check the refrigerant level to see if it's low.
@Toasty504 This is usually the problem if you fan does not work on all speeds. The trailblazer may be a little different in getting to the resistor and its' location.
@ncrdisabled I don't have a venture right now to do a video. The resistor on your venture is probably located in about the same spot as it is on the truck in this video. The procedure is probably about the same as well.
@1aauto Good info in the vid. I have a 1999 and the location of the fan resistor in behind the glovebox. Took me a long time to locate it but I manage to get it replace and all is well.. Thanks!!
Usually when the blower motor resistor goes bad you'll start to loose the lower settings. Not sure what series your Silverado is but here's a link to the blower motor resistor section for a 1500 on our website. Just copy and paste into your browser. 1aauto.com/1A/BlowerMotorResistor/Chevy/Silverado1500/-/-/2003
@TheMan16111 This video should help you out. Here's a link to the blower motor resistors on our website for your truck.There seems to be a few different types that fit that vehicle. Hope this helps you out. 1aauto.com/1A/BlowerMotorResistor/GMC/Sierra1500/-/-/2003?ATony
@MrOldFunker You could use a test light to see if there's current going to an from those components.
Can you show how to replace a resistor pack on a 2003 chevy venture . Mine has a problem that the 3 rd position does not work on the blower fan and I was told the resistor pack is going bad but I do not know where it is or how to get to it.
Thanks great videos
Thank you excellent info. have a 2005 sierra fan would only work on 5 then just stopped. watched video replaced blower motor resistor and its fixed
Thank you for watching. Please let us know how the repair comes out!
1aauto.com 888-844-3393
@TheMan16111 It it's a 2003 GMC Sierra truck the blower motor resistor removal process would be the same as shown in this video. What series is the Sierra?
Another well explained video on this model truck! Thanks 1Aauto!! You have help me learn and do so much on my truck vs other videos where I'd be guessing much more lol
Thanks for watching. 1aauto.com 866-403-3393
Thanks for the video. It sure made fixing this issue easy.
best demo so far ty
i have a 2004 silverado and had to change the resistor. got the new one at local parts store. what i have noticed with the comments on here is that no one is mentioning the plastic cover that is over the resistor. my new one was made different as far as the connector on the new resistor. the old one was at an angle and the new one was straight. the new one would not bolt back on with out the cover. so i had to cut away most of the cover to get it to slip over the new resistor.
@mobius012 Yes then is more than likely is a bad resistor.
@baldpecker66 More than likely it's the blower motor resistor.
Great video... now I know what to do...My 2002 Silverado ac doesn't work on speed 2 ..Now I'm going to buy the resister and replace it myself...would have cost me over $400 bucks at the dealer!
There's a link in the video to the part shown. If you click on it, you can purchase it on our website. 1aauto.com 888-844-3393
Hi I have a 2004 GMC 2500hd the fan only works on 5 now would this be the same procedure form my truck , The video was spot on I plan on fixing in the spring cause it's COLD out can I get the part from your site , Thanks
@1aauto Would you believe that it started to operate again that evening? I checked the fuses and controls, nothing noted that would inhibit it.
Your videos are extremely helpful. Thank you for all your hard work.
Video helped me change mine in my gmc 2005 1500. Now though the air that comes out has a weird smell to it
2006 GMC Sierra. #5 stopped working (might have been a fuse I guess, never checked). Now 1-4 stops working intermittently. I fiddle with where it plugs in, and 1-4 usually starts working again. Is the problem ever the plug itself that plugs into the resistor????
Great Video, I have a 2003 chevy avalanche 1500. For the last 2 weeks the blower motor would make a surging or pulsing sound when on any of the speeds. Then today the blower won't turn on at all. Do you think it is the blower resister or the motor itself?
You may want to check the blower motor resistor.
@1aauto Hi I have a 2003 Sierra and mine fan only really works on setting 5, it works on the other settings but when you change the speed setting there is no noticeable change in speed so would it be this or the blower motor resistor? And is there any way to test the resistor to see if it is the problem? Thank you for your service of putting up these videos. Also could you send me a link for the part from your website for which one I would need. Because I am having trouble finding one.
Actually you turned the resistor 180 from how the original was installed--you can see with the 2 side by side that the cable is coming out the other side.
Anyway thanks for the help, my blower randomly stayed on after lunch today resulting in a dead battery, and this is what I need to do.
Good video. I will be purchasing one from your shop soon.
+John Deer Thanks for watching. If any of our viewers needs to make this repair, we carry the auto repair part shown in this video on our website. Here is a link to them www.1aauto.com/1A/BlowerMotorResistor/Chevy/Silverado/1AHBR00009?TH-cam&CTA+Comment&O7DqaqHTCzw
On a 1996 Silverado, manual AC control, same type as this one is, no fan at all. Same issue or a dead fan?
My 05 quit working on 5 also but at one time it was blowing with the head unit out. Is that sound like a resistor and do u see that the lights in the head unit goes out alot
I have a 2005 Silverado, A/C quit blowing on 5 today but, blows cold air on speeds 1-4. Does this sound like the resistor? If so, would this be a similar process to change it out?
My 1990 GMC V2500 suburban is having heater issues. The heat doesn't come on at all but as I am driving and the truck warms up I can feel (a trickle) of warm air with no force behind it. are their any tests that you know of to see which part in bad besides just ripping it apart and checking piece by piece?
Great video! I was able to do this job on my own fairly easily. However, I have noticed my speeds have started to go away, again. If I replaced the resistor, do I now need to replace the blower motor? And if that is the case, will I need to replace the resistor again?
Thanks!
Typically the blower motor resistor controls the speeds. You may want to check the plug end that connects to the blower motor resistor to see if it is damaged from being overheated. If it is, you should change the plug end. Hope this helps you out. 1aauto.com
1A Auto Parts where does one obtain that plug end?
This video was exactly what I was looking for! I will be ordering and replacing in my 04 Silverado. Also my setting dial doesn't work so it will only blow out of the defroster. Have you made any videos for that or any advice for me to fix it? Not a problem I've ever dealt with before. Thanks!
You would need to cut the old end off and solder a new end on for the resistor if it has melted.
If the blower is not blowing hard enough, either there is an issue with a blockage in the HVAC system or it could be an issue with the motor/resistor causing it to blow slow.
@Nighthawke70 It could be a loose wire or ground somewhere if it's an intermittent issue.
Great video, I followed your instructions and everything went well, however, the plug is melted, do you know what it is called
or the part number ? I have a 2005 silverado 1500 I would appreciate it thank you.. If you have this part what is the cost
w/ shipping ?
You may want to see if the thermostat's working correctly. You could also have an air pocket in the cooling system which may be getting trapped. If the heat isn't blowing from the blower motor, check the blower motor and the blower motor resistor to see if they have power going to them. We sell new blower motors and resistors on our website 1aauto.com 888-844-3393 if you end up needing to replace one of them. Hope this helps you out.
The actuator for the blend door could be bad, or if it happens when the AC is on you may need to re-charge the AC system. Hope this helps you out. Have a great day! 1aauto.com 888-844-3393
Having the same problem with my blower controller thanks for the help.
Thank you! +garden wind
I have a 04 sierra and some times I get a ticking noise that comes from under the glove box area. I guess its around the blower motor area to be more specific. It has done it when the air is on and off. Any advice?
You may want to check the blower motor resistor to see if it's acting up.
What exactly are those big covers called underneath? My truck didn't have them when i bought it so id like to replace them. Can't find them anywhere online. I have a 2006 GMC Sierra 1500.
Thanks you guys , for this video .
Thank you for watching. Please let us know how the repair comes out! 1aauto.com 888-844-3393
@boominator6464 We currently do not have a video on this vehicle. It may be a similar process.
@faithchurch1 If all of that's fine it could be the (DRL) relay. Here's a link to them on our website. Hope this helps you out. 1aauto.com/1A/Electrical/GMC/Yukon/-/-/2001?page=3&&ATony
Do I need to drop the cover and see how many flange holes mine has before ordering the part from you? Thanks
If you are able to identify the number of holes first then that would help guarantee fit. +leighco9
My fan control knob just snapped gmc conversion van can i get the switch seperate or is the whole cluster a one piece? 2001 van

Hey do I have to tear apart the dash to replace that 5 pin relay ...I can't seem to find it
You might be able to get a new knob from the dealer or salvage yard.
Hello
I have a 07 Chevy Silverado 2500 (new body style) auto hvac control, is there much difference between the 5 speeds. Speeds 1/2/3 seem very weak speed 4+ 5 are very noticeably different. This seemed two occur after changing the 2 batteries. By chance does the control need a recalibrate or is it just the resistor pak.
Thank You
thanks for the video trying this on my 99 sierra.
Thank you for watching! Glad to be of help. Let us know how the repair turns out. 1aauto.com 888-844-3393
Thanks for watching.
I have multiple problems with my heading system. Only the highest speed will work on the fan. And the heat on the driver side setting is either the hottest or cold. I have an 04 silverado
