I have a 2009 c300. I have no power to my climate control…

Customer Question
I have a 2009...

I have a 2009 c300. I have no power to my climate control module and my engine fan runs loud while my car is running. There are no check engine lights.

Mechanic's Assistant: Is the power loss consistent, or does it fluctuate?

Just no power at all.

Mechanic's Assistant: Are you fixing your C300 yourself? What have you tried so far?

I'm still trying to figure out what the problem is. Then ill have to decide if it is in my scope or not
