Think its a GM relay?

[DashingDaryl]

My Zed usually opens and closes the left side window a crack when I open and close the door. Sometimes when I leave the car out in the sun, it does not open or close the window when I open the door.

Does this sound like a GM Module issue? Would I be lucky enough that a new relay would solve it?

Have you tried doing a window reset?

You would need to read the codes first.
It may well be that when it gets hot the seal prevents the glass from moving smoothly.
This can confuse the anti-jam protection causing the window to not move.

Whilst a reset can't hurt, I'm not sure it's that as once it has lost it's setting it wouldn't randomly remember it again later.
However, until you try it you can't be sure and it takes seconds to do.

ok, two things on my to do list:

1) Reset window
2) break out the 'ol computer and look for codes
