CLS W218 Climate issues - resistor?

[Trefor1]

Hi.

I've had a problem the last few months. When the car is first started on a cold or damp day the climate control goes full blast and no buttons work, it ignores me and blasts away for a few minutes. Usually after 5 minutes or so it then works just fine. Even the 'Off' button is not working.

I'm suspecting this is the resistor pack starting to go? Any other suggestions?

Also, where is it? Is it the same part as an E class, I'm guessing so?

Thanks.

Yes I agree.

Had same symptoms on a Crossfire/SLK and it was the resister.

Not sure where it is on the CLS though.

Looks like an expensive part from MB. I think I may go for a secondhand part in this case.

I'm guessing it is located in the blower unit under the glovebox somewhere, I will have a rummage once the weather improves a little.
