      heck fuses S and T in the fuse box just to the right of the master cylinder. If the blower motor is not working, try these diagnostic steps I'm listing for you.

      1. With the ignition switch in the on position, use a heavy gauge jumper wire to apply ground to the blower motor wire that is not Red. This wire color varies and is not set by the manufacturer. The Red wire should be B+. When a ground is applied at the wire that is not Red at the blower motor, the blower should run at full speed. If the blower does not run during the test, then the motor is defective.

      2. If the blower motor runs in the previous step, then test for a good ground at the blower regulator Brown wire and a good B+ at the blower regulator Grey/Red wire. The regulator is mounted to the blower motor case in plain sight.

      3. If the previous tests are OK, then using a voltmeter test for voltage at the blower regulator Gray/Green signal wire. This voltage should change as the blower speed is changed at the A/C control. The voltage typically varies around 2 to 6 volts.

      4. If the previous tests all pass, the blower regulator is defective.

      5. If the blower regulator is defective, it is recommended that the blower motor be replaced at the same time.

      Blower motor regulator replacement is recommended anytime a faulty blower motor is replaced, due to the high current stress placed on the blower regulator caused by a failing blower motor.

    What is a service c warning
    • Jimm
      6/16/2012 Jimm
      Mercedes service C consists of:

      Change oil
      Oil filter
      Top off all fluids
      Lubricate everything
      AC filter (probably that is the cabin filter)
      Reset system

      Suggest you purchase an inexpensive repair manual and learn to do these basics yourself - to save anywhere from $175.00 on up.

      Usually, the engine oil filter is located at the engine front lower corner - next to the oil pan and front drive belt.
