I have a 94 ZJ. The power window switches at all 3 passenger doors are not working, although I can control all 4 windows from the driver's side door master conroller. I removed and inspected the pwr window lock/unlock button on the master conroller and could not detect any issues. I checked the fuses and they were all good. I suspect the probelm could be in one of the relays, but do not know which one, or how to test them. Or else it could be a disconnected or failed wire, but do not know where to check. Has anyone had similar issues and able to fix it without going to a repair shop? Your feedback is greatly appreciated!!!
