Asked by Flgatorfan Aug 03, 2014 at 01:56 PM about the 2002 Mercedes-Benz SLK-Class SLK 320

Question type: Maintenance & Repair

Checked the Temperature Sending Unit by unpluging the TSU and no change! Also, removed TSU and checked visually which told me nothing. If the TSU was open, would I be seeing the same problem??

Is your ac on? If so they should be running all the time at idle.

Don't think it has a relay! Direct input to Cooling Fan is from a Control Module.
