    Looks good

Looks like it's good so far.  Still have to install it but I need to fabricate for that cause I'm missing parts on the truck.

*by J***M on Reviewed in the United States on March 21, 2021*

This Blazer/Jimmy/Suburban rear window motor did not work right out of the box.  Not so much as a click or hum out of it after installation.  I verified that I had good voltage as well as a good ground.  Even though I have a #10 AWG wire running from the vehicle frame directly to the window motor mounting screw, I went ahead and sanded the paint off the motor mounting surface and the motor mounting frame just to ensure there was no loss of ground, no luck.  I borrowed a motor from a friend that was known to be a good working motor to test my wiring harness/switches, the borrowed motor worked flawlessly in my vehicle.The return.........Yes seller accepted the motor for return after several back and forth emails, yet they would not cover the $22 return shipping cost on their defective part.  I ended up paying about $50 more than what this motor cost when I picked a motor up at a local NAPA that came with a 1 year warranty, free returns, and works!
