imagin if you repaired airplanes ! now go back to that headlight motor and reverse the wires

Did that and the wire started melt.

7Jimmy7 is on the right track. The motor is reversible. When you turn on the headlights positive (+) power is fed to the motor through one wire and the motor is grounded through the outer metal casing to the chassis so the headlight door flips up. When you turn off the headlights power is fed to the motor through the other wire and reverses the motor so the door flips down. HTH. -Jim

Triple check the wiring and if there are any instructions, re-read them. If you have wire melting, than you don't have a proper fuse and your ground wire and lead wire are crossing somewhere. Check the wires for wear, breaks or open exposed wires that may be shorting out. Keep the old motors as they will be wort something to someone as they can be rebuilt, and it it is a wiring problem, the motor may not be the original issue.

This headlight motor is three wire motor if it was a two wire motor you could switch the wire to change direction of the motor, how ever with three wire motor is not that simple you have position relay to contend with for each motor, I think the magnet are not installed right in the, motor, the polarity is backward magnet are south and north, I think I need rotate the magnets 180 deg that should make motor work in the right direction.
