I have many problems with my '94 E420. I will start with the intermittent problems that can happen between startings or in the middle of a Sunday drive. Sometimes they work, sometimes they don't.
- Automatic window down switch for the driver and front passenger
-Air recirculation switch
-Idle speed accuator
-Sunroof auto close
-Lights behind the AC cluster
I also seem to burn through tail lamps at an alarming rate. Sometimes the car will forget that there is someone depressing the gas peddle and just lose power until I can deliver a power surge. I can do this by flashing the high beams or cycling the AC motor. The check engine light is always illuminated. I have had the codes pulled, but with differing results each time. I am sad to say the mechanics seem to use their computer more than their brains.
There seems to be no pattern to this mayhem.
Please email me at firstname.lastname@example.org if you have advice or a solution other buying a new car.
