Hi. I read about many problems people have with clicking noise when starting the car. Mine started about 6 mo ago, and was unable to control the direction of the air flow(dash,legs,etc.) Then it stopped. About 1 month ago started again, this time the air blows only to feet area. Please help! I've worked on cars before so I'm not scared, just don't know where to start.

 

I forgot to mention that I have a c240 2001
