I have been searching threads but cannot find a solution to my power window problem in my 2001 Jeep Grand Cherokee limited. I joined the site today and posted a question for anyone who may have been through this but I cannot get the power windows to work. found broken wires in the door jam and have a new master control switch changed the fuse in the power distribution bow. I need to see what to do next or find a wiring diagram for the power windows so I can trouble shoot further.

 

Good Morning from South Georgia. I am going crazy with this electrical problem on my 01 Grand Cherokee Limited 4x4. I recently bought this jeep and the previous owner told me the windows quit rolling up and down a few months ago. he was told the master window switch was bad so I ordered one the same day I bought the jeep. I swapped them out and still no power. I started troubleshooting the Vehicle and checked the #12 fuse under the hood in the power distribution box and it was good so I pulled the cannon plug in the door jam and did not have power running to it. I opened the rubber protection cover in the door jam and found two broken wires a black wire that I assume is the ground and a Brown wire with a blue strip these wires were heaver gauge then the rest so I assume the Black is the ground and the brown is a Power wire. after soldering them and coating them with heat shrink I plugged the cannon plug back together and checked for power at the plug that goes into the new master window switch. I have 12.5 volts from the brown/blue stripe wire now and the black is the ground. The power door locks will now work and the power mirror on the drivers side, but the windows still will not go up and down. I then pulled the cannon plug to the drivers window motor and used a jumper wire to give it power and it rolled down and the I reversed the power to it and it rolled back up fine so my window motor is ok.


I need a wiring diagram for all of the wires coming into the door so I can see if there is a break somewhere on a different wire.


I also was wondering if there is a break in the harness to one of the other doors will this cause all of the windows not to work?


Has anyone had this problem or have any advice as to what to check next. is there a relay or circuit breaker for the power windows. could this new switch be bad? I am getting frustrated at this point. PLEASE
