Are the motors making any noise at all when he turns on the lights? If not, power might not be getting to the motors. Trace the wires back from the headlight motors and make sure they are not damaged and that they are plugged in securely.

I emailed him this response he didn't say it made any noise at all and will have him check the wiring etc but both headlights isn't there a common fuse or something?Kinda unlikely both motors suddenly went out

I have a schematic diagram from my 85 Helm's manual if that will help. Let me know and I will e-mail it to you.

Direct him to that link Agent86 posted if he gets stuck. Looks like there was some good troubleshooting procedures listed as well as the schematic.

Check to see if the isolation relay and/or headlamp relays have power and grounds. The relays are located in the LH front wheelwell under a cover held on by 2 7MM bolts.

Good luck!

Sorry, Vincent, but this guy hasn't been seen in 14 years. He's probably not going to respond.

If you have a problem, you need to start a new thread, not respond the Zombie!
