I had repaired and lubed the front power window motors a couple of months ago, an easy job, but neither of the rear windows worked. I had hoped it was just the switches, but it was more than that.
Both of the rear motors turned out to be completely seized up. Getting the motors and regulators out was a real challenge, as the regulator should be run up and down to access the screws that connect the arm to the window channel. I eventually got the right one out and replaced the seized motor with one of a pair from some mid ’60’s Cadillac regulators I’d saved for 35 years. I didn’t realize until I’d spent almost an hour unsuccessfully trying to reinstall it that the motors are right and left hand. I’d put the left motor on the right and it wouldn’t go back in.
So, I started over. Once I had the correct side motor on the regulator, it went easier. Aligning the glass was easier than I thought, that part of the job went smoothly.
The drivers side was a piece of cake after the right side. After it was done and aligned, I found the switch on the drivers door didn’t operate the passenger door window. It would lower, but wouldn’t raise, and the switch felt “loose”.
Turned out the points for that switch were literally welded together, the plastic wire housing was melted, and the contacts (little metal pegs that plugged into contact sleeves in the housing) were rusty. I was able to repair that, and after reassembling the switch, all the windows work from the drivers door and their individual switches.
Another big task completed, next up, fuel and brake lines. One thing at a time.
