How do I repair my compass and temperature readout
My readout near my inside front reading lights is not operating. How do I access the bulb or wiring area?
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. 5Look 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.

That was pasted from Edmunds, a good source of information, or just but another assembly
