When removing the wiper motor, leave the mounting frame in place. If possible, do not remove the wiper drive crank from the motor shaft.
- Disconnect the negative battery cable and remove the water shield at the base of the windshield.
- Disconnect the relay rods from the wiper motor.
- Note the position of the crank arm on the shaft. When the motor is in the parked position, the arm should be about 4 degrees up from horizontal.
- Disconnect the wiring and remove the bolts to remove the motor from the frame.
- Temporarily connect the wiring and run the motor. When the wiper switch is turned OFF, the motor will stop in the parked position.
- Install the motor and connect the linkage.
- Run the motor again and make sure the arms and blades are properly positioned when the motor stops.
After looking at the schematics, I couldn't determine which subsystem may be causing your problem with the headlights. There is a daytime running lamps subsystem, but I am not sure if that's causing the problem. There are fuses involved but not sure if that's the problem.
There's a solid state headlight switch, but I'm not sure if that's a problem.
On the headlight issue, if it doesn't come back, just consider it a bug or glitch.
Have you had a battery changed on it recently?
