Hi, I seem to be having multiple problems this week.
I've noticed this week with the cooler weather that the driver'* window gets stuck while going up. I have to wait a minute, press the up button and it will go up 1/2 inch and then I have to repeat this whole process until the window is fully closed. It sounds like it might be the window motor. If so, could I replace the motor with one from a newer H body? The reason I ask is because I've experienced this sort of thing with my other H body which was a 1989 Delta. Would the newer ones work better?

Been there, done that. More than once. We all have. To my knowledge the new ones don't work any better, certainly not the ones on my 2001.

Fortunately, it is easy to change, and because there are so many failures replacement motors are easy to find.
