New to MB and the forum

Hi
I have recently gotten myself a '08 MB C220, and have enjoyed the car a lot.
Recently, when the temperatures have dropped below 0°C, I have had some troubles with my coupe fan not working.
I have tried opening the hood and turning the fan manually, wich seemed to work the first time. Tried again later the same day, but this time it did not work.
Any recommendations to what i can look at to fix the problem?

Hello and welcome

Be very careful about putting your hands anywhere near the fan with the ignition on...
Is the car getting to temp?

 

[Aleksander Stridh]

The car is getting to temp yes, but I have to leave it running for well over an hour to get rid of the condense on the windshield etc.

It should get to temp within 10-15 minutes of running.
With the AC on you should have a clear screen in no time.
If it’s taking longer you might have some water ingress issues. Clean the scuttle drains at the bottom of the windscreen. You might have water in the SAM (signal acquisition module) which could be the source of your fan issues

Or, the AC is not actually on because of the low temps?

I’ve not known my AC not work because it’s cold outside. The AC should be used in the winter as well as summer as it dries the air which clears the screen faster

On all cars, it switches off at around 3C or it freezes up.

Welcome, Aleksander.

Thank you for helping.
I contacted the previous owner, who explained that I had to leave it on AUTO for a minute before the fan worked.

Is AC here to mean 'Climate Control' ? If not, then do you set the temp dial to the colder side in winter to blow cold air into the cabin ? Please help to allay my confusion.

AC will cool the air for you in the summer (when the temp is set low) it also works in the winter to dry the air at any temperature you set on the controls. You don’t need the temperature controls set to cold for the AC to work.

Depending upon your setup you’ll have an AC or ECO switch. Have AC switched on and the temp at whatever you (or the management) require.
Older MB’s used to have the AC light on when the AC as off. They’ve gone to industry convention now and the red AC light is on when the AC is on.

(I preferred it with the light showing it was off as red lights denote a problem to me)
