Headlights Don't Work

[Craner8]

Electrical problem. Noticed low beam lights weren't working other day. Then they came on, then out. Then, high beams went out. Replaced dimmer switch with a Napa replacement today. No change. Replaced the headlight switch with a Napa switch today, no change. The tachometer went out three weeks ago so replaced it today and it works fine. When I put the AC back in the blower on it rattled, then stopped working. Also, the brake lights are out. Ground somewhere? Fuses ok. Any ideas? Any connection to all of the problems, or separate issues. I can live without the AC for awhile but need lights. Thanks in advance.

my head lights did that same thing a few month ago. It ended up being a broken ground wire behind the head light that's all i got for help for now best of luck

Thanks. I'll track down the grounds and find the problem.

When my head lights went out on my 85, it turned out to be the connector to the dimmer switch. The connections had gotten bad & generated enough heat to melt that plastic connector. I had a spare on a parts Scrambler I spliced in & everything was good. I plan to convert to relays under the hood instead of having full power flow through the switch. But sounds like a ground problem in your case.
