IF you are saying that it appears that the heater is blowing all the time then it is the air blend door that is stuck. If you can look under the dash on the passenger side, you should see some controls for it. They might be broken or stuck. On the other hand if the air conditioner compressor is not coming on then there is a problem with the freon in the system or the compressor has a blown fuse

SOURCE: No matter were I put vent control always blowing hot air

THIS PROBLEM IS CAUSED BY A FAILED PART CALLED A "AIR TEMPERATURE CONTROL BLEND DOOR ACUATOR MOTOR", IT IS LOCTED IN THE AIR DUCT AT THE BLEND DOOR APPROX CENTER OF DASH, IN MOST CASES THE DASH MUST BE REMOVED TO SERVICE THIS MOTOR..

SOURCE: My 1989 Lincoln Town Car is blowing hot air all the time..

I have the same problem in my 1997 model. I was told that it is a actuator switch located in the system behind the glove box. The part is about 30.00, but labor to remove the dash to get to it is about 600.00.

Could be a number of possibilities. However, the most likely is loss of freon. The O-ring seals at a number of line connections tend to leak over time. There are other mechanical and electrical possibilities but you should first have someone check the freon charge with a set of gauges to measure the pressures. It might cost you a bit to have it tested but the pressure reading will tell you a LOT of things. In the long run it will save you money over guess-work.

When i get in my jimmy to go to work its blowing hot air( with the heater on of course) and then there is a creaking noise coming from the blower motor area, then the heater will start blowing cold air...


Because the Main Gear in the Blend Motor has cracked or teeth have chipped and is now not keeping the heat/cold door to the Hot position. 3 fixes: Buy a new Blend motor, takes about 5mins to replace. Buy a new Blend Motor Gear, will take about 30mins to fix. Repair current gear with Epoxy, takes about 30mins and 12hrs for the glue to set up strong enough to use it.

On my 1995 chevy blazer s-10 my face vents are not blowing air


Your heater valve is stuck open, also in a pinch you can crimp off your hose to the heater coil at fire wall. Try to find the heater valve vacumb hose under the hood see if it is bad and fixit. or some models have a cable to the valve could be broken.

Fully warmed up; blowing hot and cold; Suzuki XL-7


Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.
