    Recently bought a 1997 Mercury Mountaineer. All of a sudden the headlights didn't work. Found a spare headlight switch in the back of the car from previous owner. Looked at switch and pigtail was somewhat melted but was running fine according to voltage regulator.

    Light switch power seems to be running at 14.5 volts.

    Got it looked at, they said it needed new headlight switch and new pigtail, but as previously stated, pigtail seems to be fine.

    After hours of internet search, discovered it might be the headlight relay, which was also difficult to locate. Replaced the relay and the switch and lights are now working fine, but the switch is hot and I'm concerned I may encounter same problem.

    Ideas? What could be causing the switch to be hot? Where else can I troubleshoot? Anyone else have this problem?

    Thanks for the help!

    Are the headlights factory or aftermarket? Are their any auxiliary lights that come on at the same time?
