    Please Help... I have 1994 SL500 whose interior lights have stopped working as follows;

    No Dash Lights
    No Radio illumination
    No Door Panel seat adjustment illumination

    When this initially happened, every now and then the lights would come on on start-up with the head lights switched on but would not stay on for very long.

    2 wiring harnesses have been replaced (starter and main)

    Door lights (DS and PS) work fine as well as the dome/map lights.
    Recently replaced complete dome/map light unit (near the rear view mirror) because it has cracked to bits from the Arizona sun, but it had no effect on the other lighting.

    A few things seem to have progressed such as
    Cigar Lighter consistently blows its fuse.
    Seat electronics will only adjust if the doors are open, door closed and
    ignition on does nothing to allow for seat adjustment.
    Drivers door lock can only be manually locked if the door is open.

    are all related or are they separate issues.

    hi, Bob, a friend, Chris Souch has told me how brilliant you have been when asked for advice, and i was wondering if i too could pick your brains.

    i have only owned my sl 300, r129 for approx 1 month and it came with several issues.

    1st- central locking didn’t work, the pump had a melted motor
    i replaced the motor, now it runs for 2 seconds and blows a fuse, i put a larger fuse in it and it continually runs, untill the motor gets hot again.
    now disconnected.

    2nd - hard top is on, roll bar is up, switch doesn’t do anything.
    when you turn the ignition on, the light comes on, then goes off.
    i cannot get it to go down

    3rd - the hard top is on, when i pull the roof button, the light flashes and nothing from the pump. i put 12v on the pump and it appears to work, but nothing happens electronically.

    i have read the posts about clearing codes, but i don't want to try anything without some expert advice.

    please could you help with the above

    many thanks
    lee

    Hello Mr. Terry. I've been referred to you for help on a year 2000 SL500. My father and I just recently removed the entire soft top and replaced it, the job took about 8 hours but it was completed, for the most part, successfully. When we first began to test out the open/close of the soft top, we noticed the cover that covers the soft top compartment would not close when the top was down, but when putting the top back up it closed no problem. Just this morning, we go to check if we mis-connected any valves at the valve blocks, everything was perfectly fine. But NOW, we lost all power to the soft top, the windows, the roll bar, the car won't even start. We don't know whether the problems are all related, please help! ReggyElizer@gmail.com

    Hey Bob, Haven't met you yet but they say you are the one to talk to, We are working on a 97 sl320, that we have replaced all the hydraulic pumps in, once replaced we filled the resivior up and ran the top to cycle fluid, once cycled we found that the microswitch on the left bow was reinstalled backwards, not allowing the switch to activate, then the fun started. We took the car to a mercedes dealer here in Baltimore and had the codes cleared and started over, but now the top will cycle one time and thats it, has to be reset and cleared. Just looking for any input/Help!! Thanks for your time ,Bill Automotive Accents

    Hello Bob, In reviewing the forum I have found a few references to a guide you sent to folks on accessing the blower motor in the sl500 ( I have a 1990). If you still happen to have a copy of this information it would be greatly appreciated.
    Thanks in advance

    Hi Bob. I just bought an e220 coupe and was interested in your pic chip code counter. My son uses these things at school, pic chips, not Mercs!! so he will be building a unit. Do you have the flowchart for the pict program please.
