I had same problem with my 1994 SL600. Also when this happens you will lose your interior door lights when you open the doors. My problem was solved by taking out the, A-white 40 amp 12V Relay and cleaning off the 6-prongs and reinstalling. It is located in the box underhood ahead of the main fuse box. Just need a phillips screwdriver. It is the fartherest relay in back left. I had to pull the one out in front of it to be able to remove the white one. You can hear it click when you push in dooropen switch. When working right you do not hear it. Hope this helps.

Use the numbered buttons on the radio to enter the code, then change the station to activate it. On few of the old models, we have to pull the radio out, hook up a tool to the rear and play with the buttons and activate it.
Let me know, if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Reset your Mercedes-Benz key by placing the key in the ignition of your vehicle while the vehicle is turned off. Do not turn on the vehicle. Press a finger on the "lock" button of your key fob while the key is in the Mercedes' ignition.
Pull the key out of the ignition while continuing to hold the "lock" button down. Continue to hold the "lock" button for the duration of the key resetting process
Use another finger to push down on the "unlock" button five consecutive times. Keep holding down the "lock" button.
Release the "lock" button. This is the end of the resetting process for your Mercedes-Benz. Use your key fob to ensure it is properly working
