electronic window issues. may have found problem

[BigRAWesty]

Well my apologies..
All windows but drivers are working... I swear this wasn't the case the other day but will monitor. I'm still suspect of the lock button but it could have been pure coincidence that the amp unit failed at that time.
So now it's just a wait for the new amp unit.
I have done some research and it seems pretty much any nissan around the 1990-95 era ran these modules.
I have a mate who has a 180sx module so for $50 delivered its a but load cheaper than new..
I will prevail with this pita

I`ve had a problem with the drivers window on and off for some time then the other day I pulled module apart but all was ok so I pulled the switch apart and there was the problem, just dirty so a clean up and all is ok now

Yea have pulled the switches apart some time back and cleaned all the contacts.
Will wait till I get the amp unit and see how we go

Looking at the wiring diagram the amp only controls the diver side door window only (for both manual and auto up). With the amp disconnected and the front driver side switch connected all other windows should work.

Flex, could yourself or another electrician look at the drawings and see if the drivers can bypass the amp?
Bought 1 and was a dud. Sent it back but in all honesty I don't care if it's not auto, I just want it working..

Looking at the window diagram it doesn't look easy to remove the window amp. Can't even tell if the drivers side switch can handle the current of the electric motor (On the GU Patrol the drivers window switch is a low current type). What was wrong with the new one you bought?

[BigRAWesty]

Dunno. Didn't work so sent it back under warranty..
So how are the rest wired. If they pypass the amp are they still triggering a relay somewhere?
I've removed the amp and all the other windows work from drivers door, it's just the drivers window which doesn't.

I'm guessing the amp woukd have 6 inputs and 2 outputs (auto up and down, manual up and down, power feed to the amp, then feed to motor)..
I'm thinking take the feed from the manual up and down to the motor.
But yea I'm unsure

GQ Power Window Schematic.jpg

This is the wiring diagram for the GQ electric windows. There is one relay that supplies power to all the window motors, however this relay is trigger by ignition. From the diagram it looks like the module has 8 wires?

[BigRAWesty]

So could I find the power wire (blue or white) and connect to motor, then green to the blue or white traced wire?? Or would motor go to earth??

Make yourself a 3 pin bridging harness.

Disconnect the amp and connect the bridging harness in the Blue with a Black trace wire, White with a Blue trace wire (both of these should be at the same end of the connector) and a Black wire (opposite end of connector).

Carefully test operation. Be ready to disconnect the harness and turn ignition off if smoke starts to escape

[Flex]

Power in is the white with black trace and black, power to the motor is the blue and green. Connecting these together will make the window go up and down i.e.
Blue -> white with black trace
Green -> Black
&
Blue -> Black
Green -> white with black trace
