I know what i need to do but has anyone else had this problem: my original dimmer switch for the high/low beams began cooking at 250 degrees f, and caused the high beams to flicker and then completely shut down, just the head lights. replaced the switch, and it no longer cooked, the wires feeding the high beams warmed to about 110 degrees f. for about 2 months no problems and the other night, it started again. high beams were running about 30 mins and flickered to off and i switched to low beams without any problems. i'm going to install heavy duty relays to feed the light directly off the battery, but has any one else had this happen?
Yes. Never checked the temp of the wire tho. I replaced the high beam switch and it fixed it. Means there is a short somewhere triggering the breaker switch, which is part of the voltage regulator.
I had that problem on my GTO. I cleaned/tightened all the ground connections, replaced the voltage regulator, replaced the dimmer switch and added a redundant ground from the headlight ground to the core support. But even with all that, they still flickered when I turned the brights on. Turned out that my brand new headlight switch was defective!
I had problems with "Spook" 64 Crown Coupe. There were corrosion probs in the plugs for the wiring harness at the firewall. It was affecting voltage to the lights, and the whole car in some cases. Thus the name of the car thought it was haunted lol
Ford had a lot of issues with headlight switches in the late 80's/early 90's. They were running too much power through the switch and over time they could get too hot and cause the issues you saw. The fix as you are doing is to install relays so they take all of the power and the switch just operates the relays.
Smoked Multi-Functioning Switch My 1989 Crown Vic had smoke pouring out of the steering column when it was still a regular driver around 1997. It was the multi-function switch in the column. We had it replaced and hadn't had another issue with it, but I took the time to mail it to Ford Motor Corporation as a part that shouldn't have gone bad, and 9-10 months later I received a $100.00 check from Ford. There was no recall on those that I know of...has anyone else had that problem?
Son drives a 2004 Chrown Vic with a defective electric control module that causes his lights and other things to randomly go off. Sometimes just the tail lights which State Police don't appreciate. Lucky they drive similar Crown Victorias and know the problem. He's on a several month waiting list for a Ford company repair. Son added a direct wire to a toggle switch temporarily. Seems every newer vehicle has problems. My Dodge truck has two defective airbags. I don't remember these problems with my old cars.
