I bought a 93 civic lx 4 door sedan, the power windows and locks doesnt work, the master switch however will operator the driverside rear window. the only other way to roll the windows down is the 2 rear switches, none of the front works, I know there is relays, and a master door lock control unit, can you tell me where the relays are and the lock control unit, or shoot me in the direction i need to go to diagnose the problem i have already changed out the main window switch on the drivers side with no help.

 

did you check fuses yet.

 

I checked the 4 under the dash fuse box, all good.

 

did you check to see if you are getting power to the fron motors. do that then go to redpepperracing.com and type in 93 civic service manual. they have all the wiring diagrahms you need

 

^+1 ...check the wiring hookup...
