Power Window Issue
Need some help with a power window issue I've been having.
Just replaced the front passenger window motor/regulator on my 99 Buick Regal. The window will roll down, but not back up.
Here's what I've tried:
Different switches on the front passenger door.
Checked relays.
Checked wires at front passenger door, found no issues.
Checked voltage at front passenger switch. Good in both directions (positive and negative polarities).
Front driver master switch will not operate the front passenger window in either direction. Will operate all other windows fine.
Front driver master switch is grounded.
I'm stumped. Do I have a bad master switch? Is it possible that the master switch could be bad on just the front passenger window switch alone? Any help or guidance is appreciated.
