so after i install my double din for like 2 or 3 weeks, my a/c was working fine when they just installed the double din, 2 or 3 weeks later. My a/c wont blow cold air anymore it just warm air.

So im wondering why? and whats the issue? and what u suggest to do? take it back to the people that installed my double din? thanks

 

In for answers. Did you check the fuse/relay that controls the AC? I assume the belt is still good.

 

i reallly dont know what it is. but i think everything is good. if something wrong, then the heater wouldnt works

 

Could be a coincidence. Does the a/c need a recharge?
