HVAC Blower Motor Control Module Resistor Kit With Harness 15-81773 19260762 Compatible with Chevrolet Chevy Trailblazer Silverado Tahoe Suburban GMC Envoy Sierra Yukon

Great price. Had to splice/wire. Not air tight fit. Works as advertised. On my 2005 GMC Sierra 2500 Duramax, the truck side had has three wires in a loom and two from the fan: Loom Black = Ground, Loom Red = Always Hot, Loom Purple (small gauge) = Control, Fan Black = Ground, Fan Purple (large gauge) = Fan Power. The replacement controller has five wires and I wired as such: Red = Truck Loom Always Hot, Black = Truck Loom Ground, Blue (small gauge) = Truck Loom Control, Yellow = Truck Fan Ground, Blue (large gauge) = Truck Fan Power. The foam gasket on the new unit didn't seal well with the stock opening, so I used a little aluminum ductwork tape and the problem was solved. Just wired and is working. Before, the stock controller fried and the fan was always on - even with key off. Had to pull fuse to kill blower and save battery. We'll see how long this new replacement lasts!

I was told by a shop that the compressor was shot in a 2011 Avalanche. Another mechanic friend told me this most likely is the culprit. Replaced it and it is working fine. The problem I had was the blower started intermittently would stop and over time it quit working altogether.

I like that it was a good price fast shipping & every thing you need to install. How ever it didn’t work right out of the box. The fan on the lowest setting was to blowing to hard (auto ac) and then a week after install, it just allowed the fan blower to run even with the truck completely off and drained the battery. I replaced it from local auto store, needed that day as it was hot and need ac, but the return was easy and painless. Working in the automotive world, sometimes new parts are just bad out of the box, it happens. Wouldn’t hesitate to buy from the seller again.

Item was exactly as described. Perfect fit and fixed my problem.

Product is as described and easy to install. Great price and prefect fit.

Good

It has more plates which probably make it better than the 2 plate one that was on there.. I got it installed and it worked perfectly.. However there were 3 issues... 1. There were no instructions.. I watch a Youtube video... Luckily a mechanic made a video with my exact make and model Trailblazer... A 2003 LTX... It didn't make it all that much easier though and he even complained about the parts manufacture make that are not genuine replacements.. Over all though I paid $25.00 and some change so if it last, I'll be happy.. 2. The wholes did not line up at all... I had to think either I got the wrong part or these people were totally drunk.. I had to drill a hole for it to fit... 3. As if the hole misalignment wasn't enough. I first had to hack off an edge of it.. Luckily it was plastic and not essential... Well.. 4... actually... Okay the lack of no wiring diagram.. There probably is one but the packager probably didn't pack it.. After watching the video it cleared it up.. Thanks to that mechanic.. Also, the wires seem to match the color of the other 3 wires I had to cut and splice in.. There wasn't a lot of room to work with.. I took a few breaks because it was pretty cramped and I also didn't have wire strippers would have made it a lot easier.. I put a lot of electrical tape on it.. Bonus.. It fixed the problem of the blower staying on after the vehicle was turned off.. Also, the air seemed to blow better and be more responsive from level to level.. I'm not sure if that was my imagination or that I was just happy it was fixed and didn't have to take out the fuse every time I stopped.... This would have got 5 stars if I didn't have to do any hacking and drilling.. I would have also not minded paying $5 or $10 more if it were built properly because it made the job many times harder.

Just as good as OE quick fix
