My headlights on my 1990 T-Bird go on and off randomly, how do i fix this?

Asked by Jun 18, 2014 at 07:05 PM about the 1990 Ford Thunderbird

Question type: Maintenance & Repair

When I drive at night my headlights will randomly just turn off and sometimes they will flicker back on then go off so I have to drive holding back the stick to flash my brights, so I know my lights work just wont stay on. It didn't used to do this but now it does it every night.

Common issue. Remove the headlight switch and check the wiring. I suspect some of the wiring has burned requiring you to replace the wiring connector and some wiring to the switch.

Check all wires to lights my problem started when a plug for a was wired in and tail light shorted out.

Possibly the Lighting Control Module (LCM). There is a known issue and Ford is honoring this for 15 Year or 250,000 miles whichever comes first. Check out Ford Customer Satisfaction Program 14N01 http://www.mercurymarauder.net/forums/showthread.php?t=93010
