I dont have an answer. My 1983 mark vi is doing the same thing. I cant find the relay either. Somebody help us out please.
could be the the headlight switch, dimmer switch, headlight relay, or a problem with the wiring
The exterior lights do not have a relay. They are directly turned on by the headlight switch.
The headlights work on a totally different relay than the parking and fog lights. The headlight relay or headlight fuse is usually blown when only the parking and fog lights work.
i believe it has a faulty headlight relay.
On the '92 sunblrd SE the power for the lights to from fuse to headlight switch to dimmer switch to bulb, no relay involved.
Bulbs burned out? Headlight switch bad? Relay?
If you will notice the hazard lights are not actually flashing, reason being, the hazard flasher relay is defective. Replace it.
The blue light is the high-beam indicator. The only reason I can think of that it would be flashing is the headlight relay isn't latching into the high-beam position.
it could be the headlight relay. if not it may be in the switch.
this is my question and I was wondering because the day lights and high beams work but as soon as the low beams are switched on the daylights shut off. this is my dad's van, trying to help him fix the problem.
There is no relay. The voltage comes from the fuse box directly to the headlight switch.
The flasher relay in the tow vehicle needs to be replaced with a heavy duty one.
