Tip & How-To about Jeep Grand Cherokee
It is widely known that Jeeps have a problem with the Driver's Side Windows/Locks Control Module wiring harness that prevents all window motors and/or Power Locks from working. This may be due to the way the harness was laid out.
Over time, the wires feeding this circuits, brake or came loose from the harness connector on the drivers door.
The solution is to remove the rubber boot at the door, unplug the harness from the door and repair the broken, disconnected wires. Check all wires carefully, sometimes you can't tell they are broken because it's insulation, pay special attention to the BLACK wire, it provides the (-) ground to the whole circuit.
This simple procedure will relieve you from the great head ache that is not to be able to roll up or down your door windows.and/or power locks.
