Hi All,

I have a 1989 Coupe. A week after I bought it the button on the driver side door that locks/unlocks the doors stopped locking/unlocking the passenger side door.

And just recently the passenger window no longer goes up an down. It seemed to be responsive randomly for a couple weeks and now is always unresponsive when I hit the button.

Can anyone give me direction on where to get started troubleshooting these issues. I've had the door panel off a couple times so I'm wondering if I broke something....

Check the wiring going through the door pillar on the passenger side.

Might have one or two broken.

Check fuses, check switches, then check to see if power is going to the actuator and window motor.

if you've had the door panel off, my suspicion would be that perhaps you didn't connect things fully, and they've vibrated loose. The window control connector in particular, is difficult to mate together, so it's easy to imagine it working loose.
