All the other windows work except the drivers front window. Craig answered 2 years ago 2008 Silverado. Try wiggling relay 68 it might just not make good contact or is stuck. I am now holding up my window with wood and will not replace them any more, just to have them break again. Had to take it out through the speaker hole.
I have replaced switch to move windows' replaced window regulator in driver door. While a wiring diagram would be nice, it might not be strictly necessary in this case, because there should only be a few motors from the switch to the motor. I read on multiple forums that replacing the 175 amp master fuse, cleaning up and tightening the batter connections, and replacing the grounding wire fixed many problems. If test light does not illuminate in both positions, go to step 9. Basically, it enables the switch to reverse polarity, depending on which way you press the button.
Left front window inoperative: 1. If you have tried all the methods here and nothing seem to work just chill. Hit the same metal removing a negative cable and nothing will happen. Pardon me for butting in, but…I did find a really poor replacement regulator from a Napa store, and when I got the next replacement from the same store, it was an entirely different design, and a superior one. At this point I would recommend measuring the voltages on the switch and on the motor. Step 4 — Check the window motor It might be failing.
You can pull the master switch apart and clean all the contacts. It was however for a Dodge minivan, so this may not be relevant to your case, but I mention it guessing that the products might be made by the same few Asian manufacturers. They switch roles when you switch directions. Here is a guide and some wiring diagrams below to help us get started. When you operate the down cycle on your power window switch, it provides + power and — ground to the power window motor.
If the meter reading toggles between +12 volts and -12volts, the switch is good. The cable can break or come off the pulley. Sometimes I lose functionality of the drivers side switches that control the other doors while retaining the driver side control at least. After consultation with Quagmire86 we felt it better to provide a little more information. Also every window would roll down except for the drivers side. Finally tried taking it apart, making sure the connections were alright and buttons worked, then heated it with a heat gun for a few minutes.
However, it's been dry the last couple days. I had this problem on mine so I know what it is, still a pain, and all computer related. In that rubber boot between frame and door, wire was broken. Taking the battery lead off resets everything! I installed a new switch and there is not any power going to the motor. I pulled the control panel out and put it back together, then with dielectric grease on the plugs and the fuses were good. This can result in having a window stuck open, closed, or one that works intermittently.
My computer sucks right now so I can't upload any photos, so I'll get them up tomorrow after work. The next thing is to measure the voltages on both motor wires when you press the switch. The two main power wires I used to jump the motor up and down go into the door module. When I went back and connected it, everything worked. Think the combined action of charging the battery and the driving soved it because all was well about 3 hours after driving around doing errands. I checked all fuses and they were all okay.
But they work on the second tap of the button, not the first. John answered 3 years ago I'm not sure if you found the problem or not but I have an 07 Silverado that had the same problem. If one wire doesn't, I'd suspect that first and take it apart to see if there was a burned contact I could clean with sandpaper. I also never see any blinking lights on the window switches. See window switch under removal and installation.
The windows and the locks are on two separate circuits. One of the biggest reasons power windows fail is because of snow and ice, says Al Karam, owner of highly rated in Sterling Heights, Michigan. All you have to do is press the window button down, and hold it for two seconds once it is all the way lowered. Because the switch completes 2 separate circuits, there are 2 sets of contacts inside. I have tried a different window motor and arm unit, same result. So, if the problem is only one one side, the relay is good. I would use a test light to see what is not working I have a suspicion it is the door multiplex controller.
When I heard a faint click I let it go. We think the wires are too small and from opening and closing the door it just snapped over time. Use the switch panel to relearn the window controls. On mine, the brushes were badly worn, and the surface of the commutator where the brushes rested was discolored, suggesting to me that perhaps the power was not getting across that contact surface. Using butt connectors is commonly acceptable, and that's the easiest way to reconnect cut wires. Also it has a fuse under the passenger kick panel and in the engine pdc and both are good. Went on the old interweb found this page and did the Pwr cable thing for 30min.
