GM electric window motors

[Deleted]

My sons S10 Blazer window motor had a "sometimes" short. I purhased the new motor and knew there was some caution in removing the old one. The instructions that came with it were generic and clear as mud. My Chiltons was very vague at best. My caution to anyone changing one of these is watch out for the coil spring that keeps upward pressure on the glass. Ouch......
I did manage to replace the motor but only after 14 scratches and 3 numb finger tips later.
Just be carefull...Please.

I feel your pain.
been there done that (a couple of times)
same thing goes with the older Mopar window motors. The regulators on them are spring loaded.

BEEN EASIER AND SAFER TO CHANGE THE WHOLE DOOR.

Bob, first time it happened to me was at my job working on a GM product. regulator snapped and wacked my hand pretty good. Thought it was something that I would never forget...........2 years later, I started pulling Mopar window motors out at JY . One snapped shut on my hand. Hand was caught in the regulator. I had no choice but to simply pull it out. Hand was bleeding pretty good, so I wrapped in a towel and kept working. Now when I do a Mopar, I take the 3 bolts out of the motor using a 1/4 inch drive ratchet and a long extension, then kick the inside of the door, so the motor drops inside the door. I dont put my hands inside the door until the motor drops and the regulator snaps shut.

Ouch!!!!! I think I would have torched that door. Next time, if there is one, I'm going to vise grip the gear to the houseing.
