major power windows problem

**doughboy0032** · 07-06-2011

I tried another master switch and it was the same way. If its quiet enough you can hear the relay trip and the wires get warm instantly. When it actually rolls up for a split second its super super slow. Then when you turn on the window locks every window rolls up but of course only from the drivers side.

The slow motion of the window could be due to an aging/tired/defective motor, or it could be due to friction in the regulator mechanism and/or the glass guides. The heat is being generated because the excess friction is "over-loading" the motor. In turn, that will cause the thermal overload protection (on the motor) to trip and the motor won't resume operation until it cools down enough to reset the thermal protection device.

By "power window control", do you mean you replaced the complete motor/cable/guide assembly? If so, it is possible that the glass alignment or guides are not properly set, or the vertical guide is not properly aligned to the glass motion, causing too much drag on the glass.You need to find the cause of that friction and eliminate it. It could be due to any portion of the glass lift and guide system, including the door header seals, guide channel(s) or the alignment of the lift guide to the glass.

As for the electrical part of your question; attached is a scan of the power window wiring diagram from the FSM.
Power to all passenger position windows from the lock-out switch. If the windows all work, but ONLY from the driver's position, you probably have a bad lock-out switch OR an open circuit in the 12V feed. (Dark blue wire, Pin D on the Master (Driver's) switch).
Based on your comments regarding the lock-out switch, I think everything is working properly (electrically), but something is interfering with the glass motion.

The slow motion happens when the lockout switch(button) is in the unlock position. Before the wires and the relay gets hot, the windows window only on the drivers side will roll up but very very slow and only about 3-4 inches then the relay trips. It then will cycle on and off until I put the lockout switch(button) back into the locked position. Then all the windows move normal speed and and no heating of the wires. Only problem because the switch is locked no one but the driver side controls will work.
I tried a different window switch module(the one that controls all 4 windows and the lock out and it was the exact same issue. All windows work from drivers side switch with lock out on however none of the other doors can use their own controls. As u turn it off the drivers window only will move for a split few seconds and slow and then the wires get hot then the relay starts tripping.
