Review on 🔥 Dorman 973-409 HVAC Blower Motor Resistor Kit: High-Performance Upgrade for Cadillac, Chevrolet & GMC Models by John Roby

First let me say this product is great. It's usually around $40 at local auto parts stores, and I bought mine here used/like new for $10. So the lack of instructions is what stinks about this product. Fan connector, do not try to remove the round black fan cover. Find someone with very thin fingers instead, or take a screwdriver and try to pinch the clip holding the fan connector to the motor. (The plug is inside the fan shroud.) If you decide to remove the two screws that hold the fan shroud in place, allow an hour or more just to try to get a small screw back into the plastic to screw as the floor is damaged The car is too close to the screw and if you don't re-tighten the screw you will lose the pressure of the fan air coming out of your vents and start blowing air into the floor panel . Also, your car doesn't have a wiring diagram that is definitely colored to connect it to the black and white wires that are in the connector you just bought from Revain. I had no idea which wires connected to what and just said twist them and connect them left to right. It worked great at all fan speeds and the wiring harness no longer heated to the boil like the old one I cut off the truck. I will buy these again in the future because quite often GMs let them fail and your AC fan starts to turn off.
