PS any of you guys with dealership connects (Or WIS) can show me where this ever elusive "Lighting Control Box" is?
...I'd like to see it.
It appears that yours and my problem might arise from the same bad part--the head lamp switch.
I don't know the actual nomenclature for the part that I replaced with a used one I found on ebay, but it is part #2105451604, and I identify it as the headlamp switch and fuse block.
I replaced it myself in about an hour. Now that I know how to do it, would take about 20 minutes, and it is a small bit tricky, but it is not dirty work.
This repair/replacement totally, and I mean totally, solved my intermittent ESP/BAS/Etc. problem.
Here are my notes from the job, total cost, $63.85:
August 6, 2012:
Bought used headlamp switch on ebay, P/N: 2105451604 MBenz Headlight Switch Fuse Box $53.00 + $10.85 shipping. Removed headlight switch to get to the fuse panel that has the brake light switch fuse. This fuse panel/block is an integrated part on the headlight switch. The part number on is on the fuse panel and is 2105451604.
Anyway, How to remove headlight switch/fuse panel on a year 2000 CLK430 Cabriolet:
1. Remove the foot well panel under the steering wheel.
2. Remove a screw from under the hood release lever, and work the lever through the foot well panel, such that it no longer stops the panel from being completely removed.
3. The DB2 interface jack is also affixed to this foot well panel. Reach behind the panel to the DB2 connector, an you will find that if you squeeze the rectangular collar, and slid the collar about 3/4 of an inch, that this will allow you to unplug the connector, and you will now be able to fully remove the foot well panel.
4. Disconnect the four connectors from the light switch. In order, beginning with the connector closest to passenger side:
Big Gray connector
Big Black Connector
Small Purple Connector (Connects Display/Speedo/Etc.)
Small Black Connector
5. Disconnect Parking brake cable. First pull the nylon stop on the cable from a locking slot, then pull the ball end of the cable from the sliding portion of the parking brake pulling handle. Now you can remove the parking brake handle below the light switch.
6. After you remove the parking brake handle, you will see two screws in the cavity where the handle was. Remove those two screws. When you remove these screws, the parking brake glide will release and fall out from behind the dash. This glide has the retainer nuts for the screws you just removed.
7. Look closely toward the top of the parking brake handle cavity, and you will see a third screw at the top of the cavity, actually a bolt with a screw head. Remove this bolt.
8. Now take a small allen wrench, or any small “L” shaped prove, and work it around the edges of the housing surrounding the headlight switch. Towards the top of the surround are a couple of pressure releases which you can work loose with this “L” tool. Remove the surround.
9. After removing the surround, you will find a small screw at about 11 O’clock of the headlight switch. Remove this screw.
10. Remove the fuse panel cover on the Driver’s end of the dash, and remove the bright cadmium bolt below the fuse panel.
11. You should now be able to nurse the headlight switch/fuse panel out from behind the dash.
