Okay my cars ac stopped working. Everything on the AC control face works, it lights up etc. When I turn on the ac I can hear the fan spinning, but I can not feel any air..... This happened a few weeks ago, but started working again...........

What could this be??? Last my ac climate control is cracked and has been since I bought it, but hasn't given me any trouble until now.

 

i would check the ac relay on the passenger on the core support.
