I have rebuilt both l left and right headlight motors. The left works great, but the right as a result worked lazy. I replaced it, and I rebuilt the replacement motor and it still works lazy occasionally. It also sometimes won’t go all the way down and the motor discharges the battery overnight. When it discharges the battery it makes no sound, so there is no way to detect that it is draining the battery except that the right goes down slower than the left.
I’m thinking the motor isn’t getting enough current to go all the way down and de-energize the coil on the relay?
