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

Try getting it recharged.
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.
thermostat maybe stuk open fit a new one
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.....
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.
Because it's broken.
The heater blend door is vacuum actuated. You have a vacuum leak somewhere.
