Okay here is my problem. Everytime I turn on my climate control it makes a strange sound like it's clicking but it still provides cold air. It really ticks me off. Can somebody help, I would greatly appriciate it thanks. The air works fine it just has a weird clicking sound like its a peace of plastic hitting something.

 

could be the belt or the there is something stuck in the fan

 

Pen down the defroster vent?
