Your problem is a faulty heater control valve. The design used on these vehicles allows for hot water to flow constantly and compete with the evaporator as there is no blender door. You have to replace the valve and possibly the control head. Meanwhile, you can bypass the valve to have cold air

It sounds like you might have a blend door malfunction. Look to see how its acuated and where its located. It might be vaccum. Sometimes you can visually see the leak on or around your engine. It will be plumbed with small black rubber line usually about 1/4 inch diameter.

Replaced compressor last summer on my daughters car, was very cold last summer but this year blows hot checked freon levels, but were fine any answers would be appreciated.


If the ac compressor is running and the line is cold, it could be a blend door under the dash that is not cutting off air flow thru the heater.

Hi the heater on my Ford KA is only blowing out cold air even when turned to hot on the control knob. I recently had problems with it blowing out only hot air all the time and had a new solanoid fitted but...


Sounds like whoever did the repair work did not install the solenoid correctly or did not reassemble everything properly. If you had heat prior to the repair, the heater control panel must have been working. The mechanic must make a better diagnosis than this.

Our heater takes about 20 mins to blow warm air, and then if we are stopped at a light and the engine is idling it gets cold. Also, in the summer when we turn on the a/c it blows hotin the front and cool...


always check the coolant first, then feel both heater hoses to see if they are equally hot.
if one hot and one cold, then the heater core is clogged
if both hot then you have a blend door problem.
on the a/c there's some time a rear unit that blow cool air even the front does not

2005 KA blowing hot air out when set to cold


start car.turn on air conditioner high cool .raise hood look to see if the compressor clutch is engaged and running.if yes your ac air door could be stuck closed or the air door vacuum actutator not receiving vacuum.a vacuum line is broken or off. or the control switch bad.that control the AC and heater mode. if compressor clutch is not engagged.check for power at compressor clutch.if yes compressor clutch coil open. or the air conditioner refrigerant R 134 is low take car to a private garage with a good reputation. they wont be expensive as the dealership.have them hook car air conditioner to a manifold gauge set to check your refrigerant low side and high side pressure.

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.

Heat problem


Hi cakes32,

Seems that someone, somewhere may have forgotten to connect control cables, which operate the valve which controls the flow of coolant from the engine to the interior unit of the heater....The heater and the air conditioner, are separate, different units....They share a common housing, but have little to do with each other.....

Take it back to the body shop and tell them to check.
