good day, i have a 2007 h3 hvac problem everytime i press my snowflake button to start my a/c i get 3 flashes and turn off..
i can bypass the switch and hear, see, and feel a/ccompressor come on , and feel cold air thru vent , any solutions?

 

If your selector in the vent or defrost position, it won't recirculate. Like Doc said the AC flashes if the fan is not on.

 

Also, if the fan is turned off, the AC will not start.
