How does my A/C only work when my CRV 2004 is moving?
Asked by Julie Jun 15, 2016 at 11:57 AM about the 2004 Honda CR-V
Question type: Maintenance & Repair
A/C has always been great. Recently it only works when driving. If I stop/idle
it just blows regular air.. If the fault is with the compressor wouldn't it not work
at all? Could it be a condenser fan instead?

If the compressor is kicking on and off, you may just be low on refrigerant.
Thanks but I don't think so. The mechanic said I need a new compressor but couldn't answer me as to why it works perfectly when I'm driving. What is it about a moving car that changes how the compressor works?
How cold the air is has nothing to do with the fan, just because the mechanic said it needs a new compressor doesn't mean it really does. Like KenF said before, it is probably low on refrigerant. I would take it to a different mechanic, one that specializes in A/C repairs. It will cool better at higher engine RPM when the refrigerant is on the low side. Next time you are at a stop light put the car in neutral and rev the engine and see if that helps it cool off.
Thanks. I had to do something so I changed the compressor and this involved draining and replacing the freon. God! Over a thousand bucks!
