My display on the OBC in my 1988 325iS has little to no light so that I can barely read it during the day time and cannot see it at all at night. Does anyone know why it would do this or how to fix it?
hmmmm...I've had both these problems, but not at the same time.
It sounds like the backlight to the OBC is blown. I'll look around for the "how to"---if you can find it before me just google "replacing OBC backlight"--or similar searches....i posted the fix just a few months ago. The backlight is a "light bar" that holds two lights, I've heard of people getting some from radio shack and then soldering them in, but I just bought a new light bar for like $30 (kinda pricey for a couple of small lights!)
MY temp guage went screwy there for a while too...but mine was reading 130 F .... not likely in northern Utah. But I was lucky and after a few weeks the problem fixed itself and it started to display the right temp. I would imagine the ambient temp sensor has gone back (at least thats what every one told me) the sensor is located on the drivers side, very front end of the car. Mine is right under a screw, so it almost looks like two screws. You could try replacing that...I think new sensors run for around $50....
I'll look around for that post about replacing the OBC back light...
