I searched, and could not find an answer for this. My 2001 C320 was overheating. After reading here, and doing some diagnostic work, the fuse was a little burnt.

A week ago I lost my AC, all I had was hot air comming out. I checked the forums and saw that my Radiator fan wasnt on when I turned on the AC. The fan relay is usually located near the bottom of the engine compartment on a metal frame member. The metal acts as a heat sink to keep the fan relay cool. So, unplug the connector at the relay and repeat the check for power. If you get power, you've got a bum relay. 2. 3. 4. 5. In a little follow on from my previous thread How the heck do i access the relay for the fan in the front bumper? Also does it have a fuse? My manual seems to say not? It doesnt run at all but i ca. 1.5K. 239K views 2 years ago #fanswitch. This is a short video on how to locate, remove and test the radiator cooling fan switch on your vehicle. The cooling fan switch simply activates the 1. Engine running hot. One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly. Lp2UH.
