new guy from ohio i have a 02 stratus with 2.4 dohc just last night my heat started to not work, now it well not blow out any hot air at idle only when the rmps are up. and this some times dose not work, fan and controls seem to work fine. its at the point now where i just about have no heat it well come one for only few mins.

 

have you checked the antifreeze/coolant level,could be clogged cooling system,could be body control module acting up,a little problem on 2nd generation sedans if u have a sedan try pulling fuse #5(the one with a cover over it) in dash or unhook battery for 10 minutes; put fuse back in or rehook battery start car let idle for 5 minutes, then check controls

 

whops!
