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
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.
hi this sounds like your ac fan motor or fan speed controller is overheating on certain speeds, i would advise you to have this checked out asap, and try not to use the ac in the meantime, electrical fires are the worst and will burn unnoiticed until its too late, sorry for the bad news better safe then sorry
i have a Mercedes Benz C200 Kompressor , I just changed the plugs, air filter and oil filter and put new oil, but it's now miss firing badly can some one out there help?
