Hey so I went to turn on the a/c in my car and when i pressed mode it turned on like normal hit auto and the normal things came up but no air was coming and the little power arrow things where all blank. I know I didnt describe it to good but yeah. Then it was working okay but making some noise. Any ideas?

 

Blower Motor??? Maybe it's going bad? just get to the two wires connected to it and see if there is power and ground going to them. If so you have a bad motor.
