Chevrolet Repair: window motor, chevy pickup truck, bolts and nuts

Question
How do you replace the electric window motor in a 87 chevy pickup truck?

Answer
Hi Tom,
You need to remove the inside door panel, and then drill out some rivets.
You can replace the rivets with bolts and nuts.
Not a fun task, but it can be done in the driveway.

I assume you have checked the switches?

The wires to the motor are switched voltage AND ground. The motor is not externally grounded. So if one of the switches has a bad contact, the new motor won't work either. The switch must also provide the ground.
If you can unplug the connector at the motor, use a test light from one wire to the other, and the light should light in both up and down direction of the switch.
