I have a 2006 Dodge Stratus that is blowing cold air all the time even after the car has warmed up. Replaced the thermostat but still blowing cold air. Had it blowing warmer air once then went back to using A/C and now it's just blowing cold air.

Any help/suggestions greatly appreciated.

Thanks!

 

Wonder if there is a air gap/bubble in your heater core??? Similar thing happen to me when I changed the head gasket and thought the radiator was full but I failed to "BURP" the system. Sorry to chime in, I am interested to hear the "PROS" regarding this issue.

 

what do you have sedan or coupe? if its a sedan you could try removing fuse#5 in car(thers a cover on it that needs to be removed to get fuse out) leave fuse out for 10 minutes, put back in start car and let idle for 5 minutes don't turn anything on, then check controls see if that helps its supposed to recalibrate the system, could be air in system, heater hoses or core plugged, the blend door not working, wiring problems ,fuse blown, bad control switch

 

Thank you for the suggestion, that has fixed the problem. I now have heat and am able to switch between AC and heat with no trouble.

For some reason though it's not blowing out on the defrost setting to defrost the windshield. It's blowing hot air out of the other vents except that vent and the two vents on the side to clear the windows on the door. When I first did the reset it was blowing but has since stopped.

 

glad that worked ,sounds like you may have a problem with the mode door actuator or wiring to it
