Review on Dorman 973-508 HVAC Blower Motor Resistor Kit for Multiple Compatible Models by Kevin Cheek

Really good product, works like factory fan motor resistor. There are many half-price alternatives out there, but I don't recommend buying unbranded ones. They are much cheaper to build and on my car the heat goes to max mode when the engine is started remotely. Otherwise, the previous resistance will break and not reach the maximum setting. Dorman's new fan motor resistor fixed it and it runs like a champ.
