i lost the digital dsiplay for the temperature and compass display in the overhead console unit. any ideas in where to start the problem?
Sir,
I do not know if you had repaired your unit or not but I will detail my experience in repairing my unit today. I had exactly the same problem where the unit suddenly went blank. Here is the procedure,
1- Pressed the mode switch several times to make sure I did not put the
unit in the blank mode accidently (did not work)
2- Checked the 7.5 A fuse number 10 and it was Ok
3- Removed the two screws holding the unit to the ceiling and pulled the unit
from the front to release the two clips.
4- I used a T-10 security bit to disassamble evey thing in the unit and to
get to the printed circuit board.
5- I found two surface mount resistors next to each other with 510 printed
on them that were cracked off the board (you need magnifing glass).
They overheated (poor design) and they desoldered themselves off the
board.
6- You can resolder them or better replace them.
7- I used two 68 ohms quarter watt resistors (to reduce power disspation)
and soldered 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.
