Intermittent air coming from vents switching from cold air to hot air like something is going out but been to the mechanic several times had ground wires checked, accumulator replaced, condenser replaced, complete compressor flush, new orifice tube, hose manifold replaced, new springlock seals, o-ring and a complete evacuation and recharge of a/c unit why does the air conditioning still go from blowing nice cold air for a few miles and then blow hot air continuously
OK, the vacuum motor behind the dash has an 'actuator' that flips the plastic door up or down depending on whether the system calls for cold or hot air. There's something wrong with this system.\015\012\015\012All of the things you replac ... 2005 Ford Escape

My air conditioning all of a sudden blows hot air especially on driver's side and when I turn off engine and restart (i.e., after I have been in grocery store) it will blow cold again for awhile before blowing hot again....what could be the problem? I know it is not a freon leak as that has been tested with the dye and the dealer replaced the a/c electronic control module and it blew hot air after only about 30 minutes. Any suggestions?
That sounds like there is a problem in the air direction chamber (for lack of a better word i cannot remember the true name). At first thought I would assume that the control switches were faulty but if that has been replaced maybe it is the valves a ... 2002 Ford Thunderbird

2002 Jetta A/C is not working.. It's blowing hot air (not warm, not air that's just 'not cold', but air so hot you can't keep your hand there long)...

I just replaced my 3.4 liter motor in my 2004 monte carlo and I need to figure out why the other motor over heated and blew a head gasket. Before I replaced the motor the heater was blowing cold air and now its blowing warm air out the passengers side and cold air out the drivers side. At normal running temps 1 hose to the heater core is hot and 1 is cold. I've backflushed the core and put a hose to it to make sure there was no blockage.

I have a 92 Pontiac Sunbird SE. Blows hot air but very week. I replaced the blower motor and sensor already. I can hear the motor running the way it should but it is not blowing hot air in the vents for heat, defrost or the heater.
Does the car have A/C? I've seen where the A/C evaporator coil springs a leak and it will be soaked with refrigerant oil, then every speck of dust or dirt that comes along sticks to it. Pretty soon it's plugged solid, the air for the heater has to pa ... 1992 Pontiac Sunbird
A/C started blowing hot, was working this morning. Have replaced idle air control valve, a/c switch, and full recharge(I leaked it all out while changing the switch, and it would not take a charge, so I had a garage recharge, and replace the switch again, as I had threaded it during install) My next repair will likely be the clutch plate, but I am curious why it started blowing hot constantly all of a sudden. I have owned it for 3 weeks, and the original problem was that the a/c would work fine
