Where is the cooling fan switch located?
The manual is showing the engine has a viscous fan clutch(clutch fan). This would mean the fan clutch turns the fan initially until it reaches a certain temperature.

Radio come on but no sound
I will provide you with the radio wiring diagram to use for diagnostics. If the problem is internal in the radio, replacing it would be the fix.

Upon heavier braking, like an off ramp from an interstate, the car runs on 3 cylinders. If it is cut off and restarted, it runs fine. Thinking a fuel filter problem.

Front SAM Module Recall Notice
MARCH 2008 — Mercedes-Benz is recalling 3,283 MY 2008 S-Class and CL-Class passenger vehicles. A malfunction may occur on the Signal Acquisition and Actuation Module-Front (SAM-F) transistors. The SAM-F is a double transistor that helps control vehicle functions and the lighting of the center console. Incorrect storage of the transistors led the transistors to be exposed to excess humidity. The presence of this moisture in combination with the thermal stress during the “reflow soldering” may have damaged the transistors while could prevent them from properly functioning increasing the risk of a crash. Dealers will inspect and replace all potentially affected SAMs. The recall is expected to begin during May 2008. Owners may contact Mercedes-Benz at 1-800-367-6372. 08V122

My vehicle has no power, no crank, no sound, no power. I replaced alternator and battery. Still no power need help please.
RESPONSE
You have a blown fuse or bad connection at the battery. There is an inline fuse called a PREFUSE. This is on the red wire that connects from the battery positive tot he alternator. So you can us a multi-meter and check for battery voltage at the alternator. If you do not see battery voltage there then most likely the PREFUSE is blown. Repair or replace as needed.

What will be causing my head light and tail lights to go out. They do not come back on after I have replaced the bulbs. Consequently I think that a fuse has blown in my car. please help
RESPONSE
Possible causes would be a blown fuse as you mentioned, a failed headlight switch or lighting module failure. Furthermore some issue may be involved with the wiring harness. Or wiring connection issues but are not as common as the other reasons.
