Hey guys, I've got a fault with my power windows on my '92 E35A Galant Viento (1.8 DOHC16V) - the front passenger side window will only go UP but not DOWN from the switch on the front passenger door, however the window will not go UP or DOWN from the driver's side control panel.
Here's what I've done so far:
* Have replaced window regulator motor with a known good one, I am able to manually make the window go up and down by applying power to the motor directly.
* Have replaced the switch on the door with two known good ones (the one from the rear door which works, and the front passenger door switch from my VR-4)
* I have swapped over the control panel from my VR-4 and it's still exactly the same. The Viento control panel into the VR-4 is able to control all windows in the VR-4, and the VR-4 control panel into the Viento can control all windows except the front passenger side.
What else could it be? Is there a seperate window relay unit somewhere under the dash? On my 7G E54A Galant the driver's door control panel contains all the relays and there is a heap more wiring going to the control panel than there is on the E39A VR-4 and E35A Viento.
