Hi Joe
This is the one I found:

1- Press the mode switch several times to make sure it is not in the blank mode. OK? keep going.
2- Check the 7.5 A fuse number 10. OK keep going.
3- Remove the two screws holding the unit to the ceiling and pulled the unit
from the front to release the two clips.
4- Use a T-10 torx bit to disassamble evey thing in the unit and to
get to the printed circuit board.
5-Look for two surface mount resistors next to each other with 510 printed
on them. Check to see if they desoldered themselves off the board.
6- You can resolder them or replace them. I resoldered mine.
7- Use two 68 ohms quarter watt resistors (to reduce power disspation)
and solder them in their place.
8- You can check your work by attaching the board to the wire harness and
to the plug in the ceiling and turn ignition on.
9- If everything is Ok (as I hope) disconnect the board and reassemble the
unit and install it back.
Hopefully this will help someone in the future.
