Dorman 973-508 HVAC Blower Motor Resistor Kit Compatible with Select Models

  The fan was only blowing at one speed, and it was barely audible. I bought this in the hopes of fixing the problem, and the fan is now blowing like a jet engine once more. I spliced and wire nutted the wires together. Everything was disassembled and reassembled in about an hour. It was a very simple project, and although it has only been in place for a week, it appears to be working well. br>br>UPDATE: br>br> After about 60 days, it ceased to function. Now I'm just going to replace it with a GM OEM part and call it a day. Also, Dorman's price has risen to the point where it is now nearly identical to OEM on Rock.

This is an excellent product that performs identically to the factory blower motor resistor. There are numerous alternatives for half the price, but I do not recommend purchasing an off-brand product. They are built much more cheaply, and in my car, when the engine is started remotely, the heat comes on at full blast. Otherwise, the previous resistor would scream and not turn on to its maximum setting. Dorman's new blower motor resistor fixed it, and it's now running like a champ.

My 2007 Chevrolet Impala LT was not compatible with this part. I paid a premium for the OEM style "Direct replacement for a perfect fit every time" part, but it did not fit. It was also missing a fin. The two resistors are shown side by side in the image below. The part that was sent to me is on the top left. The one on the bottom is the original part from the car. The pegs that line it up and hold it in place go through the big holes. The screws are inserted into the small holes. None of the four holes on either side are large enough or lined up to fit the pegs, as you can see in the picture. Unfortunately, I didn't realize this until I dismantled the underside of my dash board in the dead of winter in upstate New York.

The only issue I had was that there were two screws holding it in place in all of the videos explaining how to change these. Mine didn't have any screws, but it appeared that they used a melted plastic stud to keep it in place. To keep it from falling apart, I had to cut it loose and supply screws.

It was a complete failure. I'm glad I went with the higher-priced a. As a backup, I have a Delco unit. My silverado's auto climate control had stopped working, and I was able to fix it.

It's difficult to live in the Northern United States with a car that has little or no heat. This solved my problem and was simple to set up.
