1994 e320 Coupe Sportline
My in dash readout has not worked since I purchased the car 2 years ago.
all of a sudden it starts to show the temperature when car is first started visible for maybe 5 seconds then goes blank.
when it is on it looks great LCD is clear no black spots.
any suggestions where the loose connection may be located?
I receintly purchased a new cable with temp. probe but have not attemped to install it yet
When i take the screws out of the fuse box to get at the cable connection shoud i disconnect the battery first?
thanks in advance
