Headlights Not Working

[money pit]

My headlights will only come on with the high beam switch. I checked the bulbs, I have high and low beams. I get power only on the high beam side of the plug. The fuse is good. Could it be a relay?  If so, where is the relay located? Is it on the fuse panel above the headlight fuse?  Thanks

Check the violet wire leaving the dimmer switch for power. 
If you have power there, check compartment side of the bulkkhead, then engine side.  Find where the connection is lost.

Most likely it is a bulkkhead connector issue if violet line is hot

I know this schematic is Challenger but it might help

Thanks, I'll check it out today.

My bet is the dimmer switch.
$20, plug it in and try before removing the old one.

If I jump the green wire on the high beam plug (switch disconnected) to the purple wire, I get headlights. With the headlight switch on, should I get power to the purple wire on the high beam plug?

Yes.

When lights are on, the middle wire is always hot, in low beam purple should be hot and high beams should make the red hot. If Purple isn't getting power at all then the switch is bad

Just to be clear, the high beam switch is bad, correct?  I checked the headlight switch. I have constant power to the pink and black. Power to the green wire with the headlight switch on and power to the center wire with the switch on. Thanks

Right, the floor dimmer switch is bad
