The dome light, pedal light, horn, door locks, and sometimes my trunk lock, don't work in my 89 RS. Everything else works perfectly. I think my relays are damaged, or even non existant. The car has been this way since I bought it. I think it definatly the relays, but if not what else could it be? If it is the relays where do I find them in the car?

 

the lights(dome, pedal ets...) can maybe be fixed by replacing a burnt fuse, the locks might have some bad wiring

 

i keep having the same problem with my 91, no locks or inside lights at all new fuse fixes it but i keep blowing them, haven't figured out why yet but that is a fix for the time.

you keep blowing your fuses?? do you have anything rigged to your hot wires lika fan, a button start or a killswitch?? if you keep blowing fuses try putting a higher number like instead of a twenty you can try a twenty-five. Let me know what you think

 

Check the wires in the harness from the door jamb to the door, looks like a rubber hose. They tend to break with age as the door gets opened & closed. As far as i can remember, there are no relays involved with these circuits. Check with a wiring diagram for the car.

 

Check your Cig lighter it is on the same fuse as the electrical controls you mentioned, I have seen this serveral times. The element shorts to the body of the cig lighter blows the fuse or causes things to slow way down can be intermittent.
Hope this helps

Good point. Worked for hours on a car blowing fuses for no good reason, till I found a coin in the cig lighter socket shorting things out.
