GU LHF Power window intermittently not working

[ando89]

My GU patrol Left Hand Front Window intermittently won't work. I have already replaced the motor and assembly. Before i go and replace switches and rip out wiring shortly followed by burning the car does anyone have a schematic of the electrical system i can get a copy of or can tell me what it the most likely cause.
Thanks in advanced

PM yendor mate.

Is it only that window? Is it faulty with both switches, or just one switch?

Clean the switches. They fill up with dust 'n' stuff.

Ditto. Take the switch out of the offending door and pull it apart and clean the contacts. It is a very easy quick job. A little finicky but simple.

Thanks for the quick replays fellas. i=It doesn't matter what switch i use master switch on drivers side or the switch on the door. ill have a crack at cleaning them then see what happens. Worst case ill have to run a new wire.

Had the same problem a few years ago with my GU. Seemed to be coming from a loose connection on the wiring behind the LHF kick panel. I had run some antenna coax & electrical wires thru there a couple of days before. Gave the harness a bit of a jiggle and it has been good ever since. Might be worth a look.

Thanks mate ill give that a look before i go running new wires. This problem has been around ever since i have had the car going on 3 years. i know i know I'm lazy but i HATE electrics pretty bad for a diesel mechanic i know since everything have a wire or 10 hanging off it now days

Also try re-doing a few of the earth straps for up the front of the Patrol.
You'll find the Patrol has earths for different portions of the car, eg engine
bay, dash, front passenger area then motor to chassis and motor to chassis
It goes on and on but you need to look after your earth straps

thanks fellas and lady ill have a look at all of them with any luck ill find the issue without to much hassle

Not sure if the cables rum through the same place on a GU as they do on a GQ, but have a look at the white/blue cable that runs through the bulkhead on the drivers side..... that's where mine had a break in it, but I had issues with all windows, not just one

[ando89]

YEEEEEE HAAAAAAAAA i sorted it. Pulled the switch out and swapped it with the on in the back door issue has moved to the back door. new switch is on order from Patrolapart of $85.59.

Thanks every one for your help. This just shows that KISS (Keep It Simple Stupid) really works
