Question ML350 W163 cooling fan stays on!
Hey crew, got an old 2004 ML350 that has a problem with the cooling fan runs on even after ignition off.
I feel like I have come across this before and the cooling fan is the issue and needs to be replaced, please HELP???
Thanks

Sorry to read your fan is running non-stop in safe-mode.

You'll need to scan your MB chassis modules for faults and odd conditions.

The good news are the fan itself is 100% ok... if you don't keep it spinning at destructive speeds.

Diagnosing that is not basic. It requires a modern scanner to read live data such as the Aircon pressure, Temp. sensors.
