I've got a 1996 328is E36 and my radio has been acting strange the past couple weeks.
Sometimes the radio works fine, then the next time I start the car the radio will not turn on, no blinking red LED security light either with the key removed. I checked the fuses, and none were blown. I pulled the fuses anyway and replaced them with the spares.
After a few times of pulling and re-installing fuses
ghead , the radio asked for the security code. I entered it and everything seemed to be fine. Until a few starts later when the same thing happened. No red LED, no power, no sound, until I play with the fuses and re-enter the code. And that only works temporarily.
Is it a lose wire connection in the back, or a bad head unit? Would replacing the head unit fix it, or do I need to have someone check the wiring all together?
Also my fuel gage will occasionally fall to the end of the needle travel (both full and empty sides), a simple tap usually restores it. Is this most likely a loose connection in the back that is easily fixed (I've replaced bulbs in the instrument cluster before)?
Any ideas would be greatly appreciated. Thanks!
