Comments about Dorman - TECHoice Blower Motor Speed Resistor and Harness Pigtail:

I figured out online what part was needed when the blower on my 20034 Trailblazer stopped working. I ordered the part online from Advance Auto Parts and followed the body style and model to the letter. Unfortunately, the part that was shipped was for a car with the manual temperature/blower control. The part I needed was for the auto temp/fan control model. Of course the unit fits, but the wiring is not the same. The auto control has 3 wires, the manual has 7 (1 power, 1 ground and 5 speeds as opposed to 1 power, 1 ground and 1 speed control for the FET). The part is unreturnable so I am out [$] and ended up going to the dealership and paying $95 for the CORRECT part that I could check before leaving the store. I will never buy parts online from AAP again

Comments about Dorman - TECHoice Blower Motor Speed Resistor and Harness Pigtail:

Be careful. This is NOT the unit for the cars with automatic temperature control. This is for the manual fan control only. The automatic control only has 3 wires coming in from the control module. This unit had 7, with one for each fan speed (the 3-wire version is power, ground and speed control) I bought this one and basically threw it away and purchased the correct one from the [@] so I could put eyes on it before buying it

    Good afternoon,

    Is there any documentation that details the installation of Dorman TECHoice - Blower Motor Resistor 973-410 in a 08 GM TrailBlazer SS? In particular, I am looking for a detailed explanation of how to wire the updated harness.

      Hi there M! This part does show to fit your vehicle, that said instructions are included with the item. This part fits the set up without Climate Control that may be why the connections are different.
