There is a junction block about 6 inches in front of the battery on the fender, there should be battery voltage on the big wires. The small wire is the starter solenoid. Front the junction block, the power goes to the light switch then to the ignition switch.

Good Luck

AC charge, AC dryer, Low pressure sensor, High pressure cutout, engine temp sensor, AC compressor bad, AC relay bad. CCU can be bad but I doubt it.

Check the fuses under the hood. These are the old style exposed ceramic fuses, they have been known to go out from over heating alone. It sounds like the fan is not getting power. If this is the original fan motor, I almost guarantee that the brushes are used up. (Same w/my 300sd) If thats the case and you don't see the dealer fixing it because of the potential cost, a mitsubishi eclipse 1994-1998(from a junkyard) has a small enough diameter of a fan that it fits into the mercedes housing. Be careful and you should have someone of mechanical skill there to help
