My 2005 Aveo air conditioning works great.....if I'm moving! As soon as I stop at a light or drive thru, it starts blowing hot air!!

Can anyone give me some idea what would be causing this problem?

Thanks in advance.:headshake

Make sure your radiator fan is running, and there isn't a blown fuse. Is the engine temp normal when you stop at a light?

ditto on the cooling fan--- a/c is always the first indicator of an inop cooling fan....either the relay or the motor if fan doesn't run at idle with a/c on...
