Replace the switch.
The headlamp switch controls the power to the dimmer switch and then on to the headlights.The headlamp switch controls the power to the dimmer switch and then on to the headlights.
AnswerIf the lights work on the flash to pass but do not work otherwise either the switch is bad or the dimmer switch is bad. I just am working on a 1995 Ranger and found the dimmer switch to be bad. I checked the headlight switch and that was good so I found the dimmer switch to be the problem. I jumped the wires after unplugging the dimmer switch and lights come on. Replace the headlight dimmer switch and good to go! Hope this helps.
Dimmer switch is possibly defective
Bulbs? Fuses? Relay? Dimmer switch? Headlight switch?
They as designed to "dim" when headlights are on to reduce "glare" try adjusting dash dimmer switch
The dimmer switch is defective.
Dimmer switch controls the selection of either Hi-Beam or Low-Beam headlights
Have you tried the dimmer switch? It is usually located next to the headlights switch. On pull out headlight switches, rotating the switch itself clockwise or counter clockwise is the dimmer switch and interior light switch.
Yes it could.
This is usually an indication that the dimmer switch is in need of replacement.
I'd be suspicious of the dimmer switch or a wiring connector between the dimmer switch and the headlights.
The instruments light dim for night driving when the headlights are turned on. Check to insure that your dash dimmer switch is on high. If it is, then you have a problem with either the dimmer switch or the wiring.
