Last month my air conditioner in my C230 started acting up. Sometimes it works just fine. Other times no air comes out at all. I took it into the dealer and they said it's probably the blower. They replaced it but that didn't solve the problem.

BTW, it never just goes out when I'm driving. Rather at start up it either comes on or it doesn't. I'm going to take it back in to the dealer but I'm hoping to first maybe get some suggestions on what could be causing this problem. Could this be an electrical issue?

 

did they check the switch (controls) it self?

I notice these dealers likes to swap out parts. however they should frist check out all the controls frist to see it the right signals is making it to the component.
