Whats the different issue? The harness and resistor are the cause 95% of the time, and they both can be swapped easily in the driveway, and the harness and resistor can be found relatively cheap online.

 

I paid like 30-40 for the harness at advance and like 12-18 for the resistor. U should've came on here first bro to ask bout this issue... Everybody's had this problem and can easily fixed by yourself, just paid 48$ on eBay for a NEW blower motor with free shipping and can do all the fixes my self

Dude if you can use a meter, pm me for my cell number. I'll walk you through it. Just did my sons last week for 4 bucks in terminals

 

^^^here's your answer to any problem. Listen to this man if you call him, every electrical issue I have had I search and bam he's already posted the answer I'm looking for in perfect detail.

:salute:

 

I think last time they replaced the resistor. This time, they want to change out the wiring harness. It still blows on "4" just not the first 3 fan speeds. There's simply no way in hell that I am going to shell out damn near $260 bucks for this repair. And thanks for all the replies and help. CaptainRab, if I don't get this figured out soon then you will more than likely be hearing from me. Thanks again!

Sounds like the dealer used some old stock parts.

GM actually went through and re-engineered the harness and resistor bc of this issue. You better off buying the parts and doing it yourself. It took me more time to pull it in the garage and gather the tools, then the actual install. Very minor issue, not worth trading over IMO.

 

I replaced the resistor and harness on mine in Blurred's driveway in like 20 minutes. Total Cost? $56 and some change!

It's not hard. Seriously, let us help you instead of wasting time and money with the dealer.

 

Thanks. You guys have pretty much convinced me to do it myself. I will be getting the parts soon and begin pouring over the "how to" to make sure I do this correctly. Any help/tips for this repair are, of course, welcome haha. Thanks.

Drop the glovebox by pushing in on both sides when it's open, it'll hang down. Pop out the square at the passenger side of the dash, compare the plugs on the new harness to what you have and start swapping things out one plug at a time so you don't get lost.

Voila. You'll be done in about 15 minutes.

 

I doubt seriously if the resistor pack really ever goes bad. There are 3 resistors in series and a Thermal fuse on that pack. If your working on 4, then the blower and thermal fuse are good. Clean the ground gp106 connection behind the air filter. Cut the plug off but keep it for reference as to what color wires go where. Tin the Remaining wires then twist the post on the resistor network at 45 degree angles. Add the right high temp spade connector to the wires, plug it into the resistor network and be done with it.

 

I am about to head to the advance auto parts here in town. Wish me luck, lol. Sucks that I gotta do this on my Saturday but its gotta get done. Thanks dudes.

 

Keep us posted

 

Went to 4 different parts stores in town this afternoon. Not a single one had the harness and O'Reilly's said that its a "dealer item". I did buy the resistor but had to order the harness, should be here by noon Monday. Luckily, I am off during the summer and will have time to fix it myself.

 

Well did it work?I posted on another thread last night I found a unique issue behind the passenger kick panel is a connector that burns up as well.

 

Haven't bought the part yet. Don't even know where to get it because none of the parts stores in my area even seem to know what I am talking about. I get a confused look from the employees when I ask for the harness. Then I read that it will just go out again if I replace the harness and resistor. If you could help me out, that would be great.

 

Pm for cell # and I'll give you a hand. You will need a test light to trouble shoot.

 

Trust US Striker, if done correctly it wil likely NOT go out in the life of the truck. I can almost bring that likely to a gurantee with captain's help! that guy will show you everything you need to know and then some! I am a licensed electrician....yet he is the ONLY one i go to when I myself have questions... You don't even need that damn harness more than likely. You can almost always get by without it bro.

Just talk to clint, he will help you out and he knows every trick out there man. Not to mention, 10 minutes on teh phone with him and you will gain a lifelong friend! Good luck and post up when you get it fixed!

 

Get underneath and put it on 1-3 that doesn't work... Shake the wires coming out of the resistor one at a time and figure out which one is lose. Mark it the pull the harness out. Use a small eye glass flat head and pop that pin out. Go to autozone, advance, oreilys get a new pin replace it on the wiring and yes you can get it off without screwing up the wiring its called patience. Once you have the new connector in put the wire back in the harness. Plug back into the resistor and enjoy Air between 1-3 again. I have done this on my truck my dads and now my uncle who just bough a used 355... It works! Cost about 2 smacker...

 

Wow, thanks guys. I have to get ready for a trip to Arizona but I should be able to start this process tomorrow. Captain, I will PM you soon.

 

did you ever get this issue fixed? I am having the exact same problems.

 

My buddy and myself are both having the blower motor resistor problems. Thanks for the information all!

 

hey guys im having the same issue,iit started with settings 1-3 not working,now none of them work,i wiggled the wires still nothing,so i went and replaced the resistor,still nothing should i go ahead and replace the harness now?

 

Having the same problem! Someone recommended to just take out the resistor and put a piece of wire instead. Has anyone done that before?

 

just get the resistor/harness combo from gmpartsdirect.com and install that, also scrape the paint behind the ground block by the air box, maybe throw a star washer on there too. dont be cheap

 

Just replaced mine a few weeks ago. Got parts from GMPartsDirect .com. Harness and resistor for less than $60 shipped. Took about 1.5 weeks to get and about 20 mins to install. In my case the the connector, wires and all burned up. Don't try and rig it you might cause more problems than you started with. Make sure that you sand the ground behind the air cleaner.

 

LOL! My trucks been having the same issue this week. This is great, I log on to this site and have the problem identified with a fix in less than five minutes. You guys rock!
