I am having the same trouble with my Auto HVAC. The blower seems to be stuck on the lowest setting and occasionally it would kick on for a few minutes.

My question is did you replace the blower MODULE or the blower RESISTER or both? By the amount you paid, I would assume the module.

Should I even try to replace the blower resister first? Or just spend the money and replace the module? Or are they totally separate assemblies?

I tried resetting the unit by removing HVAC B fuse for 10 sec trick, and I also tried unplugging the blower Resistor for 15 secs. Neither trick had any effect.

EDIT: I pulled off the panel under the passenger side dash. It looks like the resister (A) and the blower module (B) are separate, correct?

Toes, u can not have both. The manual HVAC uses the resistor, the auto box uses the module. You have the module. They do the same thing, of course the module has some smarts and the resistor is just that.

Ok, I understand now.

So, in the pic earlier, is the 'module' A or B or both?

Thanks for the help guys.

"A" is the module, "B" is the blower motor itself. In my post you can see what the resistor pack looks like (not the module like you have, but in the same location.

Thanks everyone for your help. I ordered the module from parts4chevys.com - $71.45 (including shipping). Before I did I called around to a few auto parts dealers to see if they carried it. I was surprised on how many wanted to correct me on the word "module" for the word "Resistor". It appears that most of them carried the resistors, but none of them carried the modules. The only parts store to carry the module was the dealership - $103.38 (plus tax).

Now I have to wait until my module comes in... weather forecasts call for mids 20's (F) for the highs mid week next week. I sure hope I get it in before then!

My First Post - just a quick thank you to all of you who post here. It really helps those of us not so knowledgeable. In this thread, I had the same issue of a blower not working. I educated myself here first, then went to Autozone. They said the correct part was the resistor - not the module. I showed them the one I'd taken out of my '03 Envoy - not a match. They could order one for $99.00.

I took the suggestion by another member here and went to Parts4chevys.com. Got the module for about $80, and the special they were running for TrailVoy (10% discount in January) will pay for the shipping charges. Way cool.

..now if it only works when it gets here.

Anyway, thanks again!

The module is for the auto climate control and the resistor is for the manual climate. Partsforchevy does not list the resistor for the envoy only the module. I had to look for it under the trailblazer. I've used partsforchevy a few time and was not really impressed(slow shipping and slow response to emails.).

Update: They were a little slow to ship, but I had the part within 5 days, so it's hard to complain. The part wasn't EXACTLY the same, but all the plugs were correct and it fit. Best of all (so far) it works.

Thanks again to all who contributed.

I've had a problem with 1-3 but 4 and 5 on my blower controls for the past couple of weeks. It's awesome to have this site as a resource to just plug it in and everyone chimes in with most all possible solutions. I LOVE THIS PLACE!!!!

What is the part number for the parts4chevy.com for the automatic heater controls (I believe I need the module) for an 05 TB LT? I would like to make sure I order the correct thing.

Thanks for the help!
