Car Forum / Mitsubishi Cars / August 2006Mirage (94) headlights not working
anyone know where to begin with the headlights. Fuses seem fine, although not sure about the large fuse under the hood. It has 4 prongs on it.. Update, they wont work on low beam. High beam works fine... >Update, they wont work on low beam. High beam works fine... Had this happen on a 1982 Toyota Corona we used to have. Replaced the headlight relay to fix it. >>Update, they wont work on low beam. High beam works fine... > > Had this happen on a 1982 Toyota Corona we used to have.

Otherwise use a 12 volt light bulb with wires on it. You'll need to find out where to look for voltages. There are some free online schematics for similar cars. Without any schematics, I would pull a headlight out and test for 12 volts from the appropriate socket pin to ground (metal on car frame). With a volt-ohm meter you could also check the headlight itself, you should get a reasonably low resistance across the low beam filament and high beam also. You could also test the headlight across your battery using some clip leads. It rather simple, you work towards the problem. Without any metering its trickier. Try testing the relay and switches if you get no voltage at the headlight sockets. GK > anyone know where to begin with the headlights.

I had a 1987 pulsar with a similar problem, nothing but hi beams, no running lights or dash lights. My pulsar had a missing voltage at the headlight switch. Without a good wiring diagram, or detailed electrical knowledge there's not much you can check. Parts swapping is expensive so I'd be sure of the cause before I invested in parts. Here's a freebee you can try to rule out the relay, steal a relay from another circuit and swap it for the headlight relay, for testing purposes. I kinda doubt this is your problem but at least you can rule it out. I'd be betting on bad dimmer, or headlight switch, sometimes you can dissassemble them and clean the contacts. Or a missing voltage, or bad ground. This is of coarse after you check the lights, fuses and relay/s and they check out. Reagrds, Chance |
