    The entire power switch cluster for windows, doors, mirrors, seat heating etc. began working intermittently. For the last few days nothing has worked at all except for last night everything worked for a few minutes

I had the same problem in my wife's 2003 Yukon Denali. The power seats and passengers side window wouldn't work. Turned out to be a blown Buss Type fuse in the Underhood Fuse Block. It is the one marked MBEC 1 50amp. Hard to tell if the are blown so look very carefully. Should look like a hoop with two shiny solderlooking bubbles on either side. On my blown fuse, it caught my attention because it looked like the solder was missing and I had to look very closely to see the bottom of the "hoop" was open. They are very hard to remove and must be pulled straight up.
This type of fuse looks like a red square with a clear plastic top showing the fuse link under the plastic. On my vehicle it is on the top row second one from the left.

SOURCE: Power Door Lock Problem

The last post by maddog1321 was exactly what I had with my right rear door. The electric locks would not lock and unlock, and you almost couldn't do it manually without my feeling I was about to break something. I took the door panel off, oiled everything and got no relief. Finally, I saw the above post and drilled out the aft-most pop-rivet. THE WINDOW WORKED PERFECTLY! I didn't drill out the forward (closest to the handle) pop-rivet because I wanted to do one at a time so the solenoid would not fall out of place. I then put a new pop-rivet in place of the one I drilled out. I then reinstalled everything and the locks work like new.

The control may have gone bad... You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. Then you can disconnect the controls and test them

Power windows got rained on won't go up


Here are some things to check, is the problem in the master switch (the drivers door switch that can control all windows.) or check each door window switch for operation. check fuses. most likely if a switch shorted because of moisture it may have blown a fuse. Here's a long shot.... if the fuses are good, try a small amount of WD40 into the switch in question. ( wd40 does not conduct electricity and will wash out the moisture if any.) The next cheapest thing is to replace the switches, very easy to do. The master switch will be the most expensive one, since it has a control for all the windows.
I have had to replace 2 switches on my "04" dodge ram, the master switch that controls all windows,door locks, and power mirrors ($140.00), and a passenger side window switch, ($26.00).
I hope this helps, please let me know.

Drivers rear window will not go up or down, stuck half way up


Remove the door panel, and disconnect the plug for the window motor. Using a test light, see if you are getting power to the plug while operating the switch. If you are, I'd replace the window motor. Being that neither the master switch and the switch on the actual door aren't working, its a pretty safe bet that its the motor.

My windows dont go up or down . I replaced driver door master switch & fuse . sometimes I reclose dr.door it worked . what would make all windows not to work ?


it sounds like you need to check power supply to the switch cluster as connection may be interupted. you can also locate the power supply and run a jumper wire to switch from another positive source and then try operating window switch. you must also have a ground wire to complete the circuit. As you open and close the door you will notice a rubber casing that goes to the door and the truck pillar which houses the wiring to and from the door to the fuse cluster. Alot of times due to the movement of the drivers door (open/closing) the wiring has the possibility of fraying and become weak which result in lose connection

Power windows and driversdoor powerlock will not work. the other 3 doorlocks work. whats wrong?


Probably bad master window switch in driver front door. Your description is vaque. If driver front door switch doesnt operate the other windows, but they all work from each of their switches, than start with the driver front door master switch. May be worth your time to check wiring in door jam before buying the switch.

No power to passenger door window or lock, drivers door ok, cannot open passenger window or lock from drivers door This is a 2003 Chevrolet Silverado truck 2500


I know this sounds strange but I believe the problem is in the drivers door. This is where the master switch is and controls the other doors. Have it tested or replaced. Hope this helps. Good luck.

Rear side windows


This may be just a case of inadvertently hitting the window lock out n th driver door window switch by mistake. Check that first. Here's some background on window operation

Principles of Operation
The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.
