The mechanical side of the window is fixed. As expected it was gummed up with dirt filled decades old grease. Just the same on the manual windows, this causes the motor to drag and pop the circuit breaker from working too hard. Here's how gummy it looked to start.
The tracks were just as gummed up.
After a cleanup in Larry's solvent tank.
The mechanism works much more smoothly now. That is when you chuck the drive cable to a cordless drill. The dash switch moved it slightly before I got started but it wouldn't click after. Just like everything else the wiring is sketchy. So I'll leave that for another day.
Both days in the shop were great for sure. I even drove the K5 down the street when I pulled it out of the garage both days. Didn't go far, but I was able to surmise a couple of things. First, the speedo won't move. It doesn't feel like it's upshifting automatically either. I tried manually from 1st to 2nd, no change. Got more to do there for sure.
