sounds like the air-conditioning expansion valve is probably not working correctly here is a way you can fix your air conditioning:

Sounds like the hig head-pressure cut=out is kicking in and shutting down the compressor. This is probably caused by not enough air being moved across the condensor coil (in front of the radiator). Check and make sure all the engine cooling fan components are in place and functional (fan clutch, shrouding, belts tight) and also check the coil for obstructions (Bug accumulation, road debris, litter). Clean the coil and radiator as much as possible at a self-service car wash, see if that doesn't help.
This can also be caused by an overcharged system (too much Freon). Sometimes when these symptoms first appear, the knee-**** response is to add another can of Freon, only to make things worse. If this is the case, I would recommend a system evacuation and service, replacing the dryer/receiver and pulling a 28mm/hg vacuum on the system, and then refilling with the proper amount of Freon, and cleaning the evaporator coils as well. This can only legally be one by an HVAC Certified technician, to insure excess Freon is not released into the atmosphere.
Hope this helps you figure it out, and good luck!

SOURCE: My heater is not blowing
I have a 2001 ford winstar and my heater is not working I slide the ac/heater switch to heat and all it does is let out a thumping sound and blow cold air out and it is starting to get cold in the morning
SOURCE: ford ka heater blows hot air all the time
Taurus does not use a heater control valve. It runs coolant thru the heater core constantly. You may have a temp blend door actuator problem or a plugged up heater core is also very common. Feel the heater hoses, they should both be very hot, it one is much cooler; you can try to back flush the core.

ok could be one of 3 things. 1 you may be out of freon. (proly spelt that wrong) 2. compresser could be bad. 3 the clutch on your compresser might not be engaging. when trucks running turn ac on and see if the front of your compresser spins or not. if it does clutch is good. but it could be that your compresser is still bad. either way i recomend you go for freon and start there. when they fill it they will tell you for sure wether or not your compresser is bad.
