Headlights Don't Work

[money pit]

When I turn on the headlights, nothing. If I turn on the high beams, the high beams come on. I checked the headlights. When I apply power to it I get low and high beams. I only get power to the high beam side of the plug when the high beams are on. I haven't checked the headlight switch. Could it be a relay. I ordered a wiring diagram, so I'm doing a lot of guessing. Thanks

The power goes out from the headlight switch to floor switch which determine which circuit is turned on , I suspect the floor switch is bad

Added the headlight wiring to the Challenger edited picture I posted on e-bodie.org

With the headlight switch on and if I disconnect the plug and jump the green wire to the purple wire, I get headlights. That means I have continuity between the wiring and headlights. With the headlight switch on, should I get power to the purple wire, for the low beams? Thanks

The green wire provides power to the floor dimmer switch from there the dimmer switch determines if the low or high beams get power so if you jump to red high beams should light , jump to purple & the low should light up .
