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.
ruud furnace only blows cold air, no heat
ihave a 1986 chevette that when i turn defrost on it blows out heat and when i put heater on it blows out only cold air? ihave a 1986 chevette that when i turn defrost on it blows out heat and when i put heater on it blows out only cold air?
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.
Try getting it recharged.
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.....
Because it's broken.
possibly thermostat stuck in the open position?
it has a dead raccoon stuck in it
Sounds like it is low on freon. Probably has a leak.
The heater blend door is vacuum actuated. You have a vacuum leak somewhere.
thermostat maybe stuk open fit a new one
There are a few possible reasonsÊthat 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.
check the thermostat dude may need replacing
check the coolant in the radiator it may be low.
You are likely in an antarctic region.
The heater is blowing out cold air only
Well it should blow cold while driving and stopped. You probably need to get your AC recharged. Hope I helped!!
Check the blend door actuator.
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.
I have changed heater core and did no good same problem as before it blows only cold air I do not understand it
checked antifreeze level???
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.
The thermostat may be stuck open.
I know he did it on Cold Wind Blows, but I'm pretty sure it's not the only one.
