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!!!
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.
@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.
Nice video, my truck is a 05 gmc p/u is there a way to test resistor and fan motor because I'm not sure which one is on the fritz. Once fan would not work then came on now nada, zilch, nothin.
@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.
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.
First off, THANK YOU! I was quoted for $750 from Chevy just to look at my AC! I just made the change from this video and it works! My only question is I bought the two hole and not the 4 hole (4 hole was about $50 more and the store didnt have any) so I could only use one bolt to put it back in and its not as snug as you would like it to be, but it appears to be working great! am I OK with this or do I need to spend the extra for the 4 hole resistor? Thanks!
@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.
@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!!
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.
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.
@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.

On a 1996 Silverado, manual AC control, same type as this one is, no fan at all. Same issue or a dead fan?

@1aauto Would you believe that it started to operate again that evening? I checked the fuses and controls, nothing noted that would inhibit it.
Nighthawke70 3 months ago
@Nighthawke70 It could be a loose wire or ground somewhere if it's an intermittent issue.

just wondering if you knew if the back blows air and the front dose not would it still be the blower motor resister?

What if all EXCEPT high speed work ? Same fix ?

@mobius012 Yes then is more than likely is a bad resistor.
