I just replace my Wifes Blower motor Resister. Let me just say it is very easy to do. Anyone that can read this can do it.

Under the dash on the passenger side you will see the back of the blower motor. Just to the left of it is the blower motor Resister. You will see the back of the resister. It has a flat plug on it. There are two 5.5mm bolts that hold it in. Pull the 2 bolts and it will come right out. Unplug the old resister. Plug the new one in and slide it back into place. Put the 2 5.5mm Bolts back in. Done!!!

Test to make sure everything is working.

Hope this helps some of you out.

And why would I do this? Am I missing something?

 

Because the resistor blows and you loose blower speeds 1,2 and 3.

Thanks for the info.

 

Like jlong said. My wifes Truck has lost 1,2,3 and all we had was 4.

 

What would cause them to blow a resistor, like that. Is it another malfunction.

 

Yes, it is use something that goes bad.

 

Thx for this information! Mine went out last night and I didn't know what the heck was going on....Glad it's just a simple resistor. The new part cost about $17 from the dealer. Couldn't get it from local parts store unless they special ordered it.

 

I just had mine go bad too. This is something that happens with all newer vehicles of all makes & models.

 

This seems to be a problem for all. That's why i have a spare one in my garage. + A spare speaker.
For those of you who have had a coly/canyon for a while would know why speakers are included in my spare parts.
Also many times beside the resistor, the casing with pins for the resistor burns out too. So i have the whole cable ready in my garage for the next time.
If there is a next time, because i put a sign on the truck that says " For sale".

 

Been having that problem for over 3 years now, keep taking it back to the dealer to be fixed, works for a little....then goes again in a few months, the a/c is too noisey at 4, so this gets really annoying.

 

i just replaced mine as well! sounds like a problem with that resister!!!

 

i just replaced mine as well! sounds like a problem with that resister!!! SORRY about the double post, i dont know how that happend :clueless :roll:

 

i just had it go out again for the second time in a WEEK!!! this time they replaced the part that the resister conects to and the resister because they told me that was causing the resister to keep blowing out. i can't remember the part but i hope this helps someone!

 

There is a much more detailed thread about this ( pictures, more info, etc ) if y'all would search.

 

When this resistor blows, do speeds 1, 2, 3 work again or are they gone until you replace the resistor?

My blower has been cutting out on speeds 1, 2, or 3 at random and then starts again on it's own. But everytime it does it, if I put it to 4 it starts right up again.

What is the part number for the new resistor?

Thanks,

Steve

Think it is in the how to area.

I have a 2007 Colorado needing the HVAC fan motor resister and wiring harness replaced. The threads have been wonderfully helpful. Does anyone have part numbers..?

 

:welcome to C'Fans.

gmpartsdirect.com has a kit that they sell that has both the harness and resistor module. It is a bit cheaper than buying the parts separate. On their website enter the part number PK15218254. Their price is $54.71 including shipping.
