I had the same problem with mine. It is your control panel for heat and A/C. Replace it and all will be okay. More likely it is the temperature control motor. A white plastic box about the size of a pack of cigarettes lying on its front. It can be seen by opening the glove box and looking straight forward of the heater control panel on the top of the big black heater/ac box under the dash. The motor adjusts the door automatically in response to the temp setting and demand for more hot or cold. It is very difficult to change without removing the top of the dash. Last time I checked, Ford wanted upwards of $200 for one. The motor can be checked by a technician by removing the control panel and powering the motor with a 9 volt battery directly to the motor control wires. If the motor moves both ways it is OK and the panel control might be the fault. If not the motor is toast. Hint, set your temp and forget it. Don't turn ac unit on and off. Any extra is just wearing out the motor.

The most common reason a automobile heater blows cold air is the water level is low. Check the water level and fill to the appropriate level.

Only blows cold air with the a/c on while driving, your cooling fan or fan clutch is bad depending on the year, make and model.......... Only blows cold air with the heater on while driving, you will have a bad or broken internal a/c - heater control door.....

Sounds like it is low on freon. Probably has a leak.

There are a few possible reasonsรŠthat an air would only blow cold when accelerating. The top two reasons are that the compressor fan might be malfunctioning or that the compression clutch isn't engaging.

Well it should blow cold while driving and stopped. You probably need to get your AC recharged. Hope I helped!!

If the furnace only blows cold air the pilot light may be out. It may also be a fuse that has blown. However, you may need to contact a licensed electrician to find the problem.

It is probably your thermostat. That will make cold air come in. It's probably stuck open. The part is only about $4.00 at Auto zone.

I know he did it on Cold Wind Blows, but I'm pretty sure it's not the only one.

An automobile's heater that blows only cold air could either be a faulty thermostat or, more likely, a faulty heater core. A trip to a mechanic or shop that specializes in radiator and cooling system repair should be able to diagnose and repair any problems.

some possibilities are. low coolant level, open thermostat, pluged heater core,
