I have a 94' C2 coupe and all of the sudden the horn stopped working and one (1) headlight stopped working.

- HORN: when I push the button I can hear the relay clicking, but nothing else happens. I checked the fuse and it is fine. Any suggestions?

- HEADLIGHT: when sitting in the car, the right headlight will not illuminate. I pulled the headlight assembly and checked the lamp, it is fine (I actually pulled the working side also and put the bulb in there to be sure, it works fine). I checked all the fuses and they appear fine. The only thing that happens when I turn the lights on is the left one is fine the right one I get a very dull glow. Any suggestions?

Appreciate any help - Pono

 

Dear Pono,
I suggest you have lost an earth for the horn and the headlight. The horn assembly (dual) is mounted in the RH wheel arch. Not far from the headlight. I would jack the RH side. Take the wheel off, remove the arch covers and look for the broken wire. I think your earth has come adrift. The stud should be on or near the horn mount assembly. You may be able to see where the wire goes when you take the headlight out. Of course you can check for 12VDC and an earth at the headlight connector as well,
