I have a 1993 Honda Civic..and all of the power windows work on each door except the front passenger door from the master switch on the driver side. Any idea what it could be? Could it also have something to do with my power locks? Because they dont work at all..Thanks

 

For the window problem, first check for a blown fuse 5 under the dash. If fuse is fine, then you might have a bad switch assembly or window motor.

For the lock problem, first check for a blown fuse 6 under the dash. If fuse is fine, then the control unit behind the driver door panel may be bad.

 

Okay..so I did check both fuses and their fine. So for the window I would need to get a new master switch? but where is the control unit for the locks? I took off the door panel but all I saw was wiring..is it the lock button itself?

 

Don't replace the switch until you show it is faulty (same for control unit). Tests are detailed in the service manual: http://hondatech.info/downloads/Auto/Manuals/Civic/
