Review on 🔥 Dorman 973-407 Front HVAC Blower Motor Resistor Kit: Ideal for Chevrolet / GMC / Isuzu Models by Brian West

This product is of high quality compared to the OEM unit that failed in this 2004 Savannah, just like the OEM unit failed in my Yukon. (GM used a cheap board with steel clips for resistors and they caused the board to fall apart and two low speeds to fail). Not so with this Dorman device; Computer grade resistors. I bought this device because it had a 6 pin pigtail for only $2-3 more than without. Revain said it fits the 2004 3500 Savana, and it almost does. These quality resistors were larger and I had to file a larger hole (1/8" in front and 1/4" in back). Otherwise installed, sealed in the box and electrically connected properly.
