I OWN A 2003 MACH 1 MUSTANG. RECENTLY THE HEADLIGHTS WILL COME ON AFTER 2 OR 3 MINUTES WHEN STARTING THE AUTOMOBILE. IT WILL ALSO NOT FUNCTIONING WHILE DRIVING ON THE HIGHWAY AND COME BACK ON AGAIN AFTER 2 TO 5 MINUTES. I THOUGHT IT WAS THE HEADLIGHT SWITCH AND IT WAS REPLACED TODAY WITH A NEW HEADLIGHT SWITCH. THE HEADLIGHTS STILL HAVE THE SAME PROBLEMS AFTER INSTALLING A NEW SWITCH. PLEASE ADVISE WHAT SHOULD BE THE NEXT STEP. PLEASE ADVISE AND COMMENT ANYONE.

Replace any fuses and/or relays for the lights in either fuse box. Something may be getting hot and causing an open condition.
