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!

Exactly what I needed and fast shipping. I appreciated the clear description so I ordered the correct item the first time.

I bought this in February and it took a few weeks before I got it installed. When it was first installed the low speed was higher than the OEM that was replaced. I could live with that,. I wasn't happy, but not worth replacingA couple weeks ago, the controller started only working intermittently. Sometimes the speed would change without any change in settings. Then the fan would shut off and come back on.Now the fan only runs about half the time.My advise would be to buy a different controller, because this one isn't high quality.Bought in February, installed early March. Stopped working in June.

Easy to install & great value compared to dealer oem. Fan speeds not quite as accurate but still works great. 2005 silverado

Works 👍

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.

This is the revised part, not the original. If you are not sure which to get, get this one. If yours has never been replaced (that you know of) this one will require you to make a simple mod to the wires. If it has already been replaced (and you did not know it) this is a simple plug & play.There are several good youtube vids on how to replace this including the mod.If you need to make the mod, have a couple butt splices & electrical tape handy.

NOT RECOMMENDED! Installed the resistor only on my 2006 Tahoe. Blower came on, but the lowest setting was way too high. Too much air. I then installed the wire harness included. It blew my 40 amp blower fuse. I removed the harness and the resistor and order another brand of better quality. On top of that, I had to drop off the package to return at my own driving expense.
