I have a 2001 Chevy Tahoe. The front passenger power window stopped
working, with the window up (thank goodness). When I actuate either the
window switch at the passenger door or the driver door (the child safety
is off) I heard a click (a relay) and nothing else happens.
I am inexperienced at working on power windows and am not even sure how
to safely remove the door trim panel without damage to the panel. Is
this a big job to repair and should I leave it to a mechanic or dealer?
I am having the same problem with my girlfriend's GMC Envoy, except on the
driver's side. I hear the relay clicking, but the window won't move. She
took it to a shop and they said the problem must be in the switch because
they tried powering the window motor itself, bypassing the switch, and the
motor works. I wrote gmpartsdirect.com for a part number, and they sent a
part number and a notice that the switch will need to be programmed. The
instructions are in the service manual. That makes me think that a
re-programming would be a good first step, rather than replacing the switch.
Anybody know how to program a door window switch?
What year is your Envoy?
A quick look at the schematic for a 2000 Envoy shows conventional power
window switches. No programming required. Also, the service procedure
makes no mention whatsoever of programming.
It is a 2003 with the extended cab. I carefully took the switch panel apart
and saw that it has a couple logic boards and many integrated circuits. At
that point I realized spraying it with contact cleaner wasn't going to fix
it. . .
You need a scan tool to program the switch. Step two (2) of the programming
2. Follow the instructions on the Techline Terminal and scan tool to program
the DDM/PDM. (Drive Door Module/Passenger Door Module)
