2004 Mercedes ML500

Radio come on but no sound, I check fuse is there a fiber optic fuse or what could it be?


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.

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

2009 Mercedes Benz R350My 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.
