You have to check all the fuse but in my case a 2009 Mercedes Benz c300 i replaced pressure sensor and the fan run perfect the air condition start working. part number has to be Original A 211 000 02 83. and is located between the motor and dash. look very deeeep
this is an indication that there is a problem in the cooling system. Check the radiator cap is operating correctly. Check for correct operation of cooling fans ( replace if you have a viscous fan hub on the fan). Have a flow test done on the radiator as there may be too many cores blocked for efficient cooling. Run the fault codes to check for air/fuel /timing issues that will affect the engine operating temperature.
If you have high temperature that means your fan is not working get the viskouse fan replaced asap or your head gasket will blow. The fan is belt driven but when the engine gets hot it spins faster on its own and this is not happening, changimg the fan is cheap and any garage can do it.
Couple of reasons. You may need to have the Radiator backflushed to remove sediment. You also have an Electric cooling fan which may be malfunctioning. They (fans) often have more than 1 speed and high speed may be broken so it can not keep up with extreme heat.
Some fans use more than 1 relay to switch the fans and the second stage relay may be bad.
Overall, the A/C coil is placed in front of the Radiator and depends on airflow to function. This makes the air available to the Radiator much hotter so the Radiator is having a hard time cooling the engine. The Electric radiator fans kick up the airflow to help both systems out.
A dirty radiator, old antifreeze, etc. can affect performance.
I hope my solution is helpful. Radiator shops can service most Brands.
The fans are radiator cooling fans. They are temperature controled so when you first start your engine in the morning they should not run - UNLESS you start it with your AC on. If you turn your AC on one of them should start operating and the other one will kick on when your engine starts getting hot.
