Whats going on people haven't a headlight problem my low beams will not come on. every thing else works except the low beam headlights. Parklights are on high beams work but no low beam. i was tryin to find the headlight relay but I can't seem to locate it does any one know where this relay is. If not i'll probably just replace the dimmer switch and see if that works.

Headlamp relay is below the dash, to the left of the steering column. its the one in the middle on the lowest row of relays.

it's the dimmer switch, auto zone has it for about $20,

Before you change anything make sure your bulbs are good. As a parts guy, I've had a number of people want to buy relays, switches etc when in reality they just needed to new bulbs. Check the easy stuff first.

yeah i just check out the wireing diagram and noticed the relays are before the dimmer switch which means the dimmer has a heavy current load going throu it. I"m going to add 2 new relays after the dimmer switch this weekend, which will make the dimmer just a switch to run on the relays instead of the headlights. Is any one with me on that, that might be confusing to sum but i do this to all my project old school cars, to keep from buring out headlight switches and dimmer switches.

Sounds like a great plan......... We definitely have a weak wiring system for the lighting on our cars.

You should ACTUALLY think about upgrading the entire harness. DO a <search> for Whisperjet... quite a few threads about it.

No dim lights. I have running lights, high beams, and turn signal everything works. When I hit my dimmer switch it clicks but head lights just go out I have to keep them on high beams. Is this more likely the dimmer switch or head light relay?

As all the other posts in this thread have stated, it's the dimmer switch.
