If you've done all that you say, then the next logical thing would be to check the continuity of the circuit. If you've replaced the switch place a propbe at the fuse block and the other probe at the switch to see if there is any power reaching the switch. If there is power to the switch, then check from the switch to one of the window motors. I suspect that one of the wires between the switch and the window motor(s) is probably broken or shorted to ground. ALSO: Does your vehicle have a safety child lock-out switch for the windows? Make sure that it is not in the lock position.
The window lock is faulty. It happened on my Jeep and i replaced the driver's dorr control module and it worked just fine...until that one broke too.
Because the master control on the drivers door has separate areas for all windows. Start by checking power feeds at the drivers door switch.
Check to make sure that the windows haven't popped off the track. This would cause the windows in your 2002 Envoy to become stuck and not go down. If you replaced the driver's side master power switch and the locks work but the windows just make a clicking sound, this could help.
If the windows on your 2002 Envoy will not go down, and you have replaced the driver's side master power switch, you should make sure that the window hasn't come off track. This would prevent the windows from going down and it would make a clicking sound.
more than likely you will have to replace the drivers side master switch
I have a 93 Honda Civic LX with the same problem. I had everything replaced and nothing worked. I took it to a very good electrician and he figured out the problem for me. Its a connector that connects the Master window switch to the rest of the car windows. Mine had moisture damage so it worked on and off and only with certain windows. But the rest of the window switches operated the windows fine. It should be in the door panel/hidden around the door hinge.
does 04 gm envoy master window control have to be programed by dealer when replaced.
Bad master control switch? Although a bad master control switch could be the culprit ... However, another real possibility is a faulty/inop window regulator. I have a 2001 4.0 and have replaced 3 of the 4 window regulators. Dealer/independent shop informed me that the window regulators in the 2001 Aurora were "cheaply made" and are frequently the reason for inop power windows. I live in northeast Ohio area and have spent anywhere from $250 - $400 to have the window regulators replaced.
Power windows I assume. Check the fuse. If it is still good, it is probably the drivers side master switch that is bad.
If they both don't work, check the fuse. Under the dash on the drivers side. Could be a problem with the master control switch on the drivers door? I've had to replace the window regulators and both door switches, one at a time, never both at the same time.
there are 3 control units.1 behind the drivers side fuse panel,1 behind the passenger side fuse panel and the last is on the master power window switch control in the drivers door.
a fault. it's just broken.
