90LX Power Window Trouble- Passenger side wont roll down via switch.

For my drag car build, I wanted to keep power windows.
Before teardown- the passenger window was acting weird. I replaced the motor and it would roll up, but not down.

I've stripped the main body harness and rewired with a Ron Francis kit as the OEM wiring was in bad shape. I left the power mirrors/locks/windows wiring in place.

Ron Francis has a power window Feed but that's all you get.

If I apply 12v to the Pink wire, my drivers window will go up and down from the OEM switch no problem. The passenger side window switch on the Drivers side does NOTHING. The passenger side window switch will roll the window UP, but not Down.

If I apply power and ground direct to the motor, it will roll down.

Any thoughts?

Those switches go bad all the time. Try to find originals as the repros are worse in some cases.
 
Try spraying contact cleaner on the driver's side switch for the passenger window. Apply a couple of times and see if you can get the window to go down.
