    Who says its "proper" it's not proper unless it's getting cool inside your car! Bring it to a better shop and have them look it over!!! Stuff like this makes me just shake my head. I would have fired anyone working for me if they had ever told that to a customer!!! (without fixing it)

It will not blow hot air. I have checked the coolant (its fine), checked all hoses, no leaks, and the fuse for the climate control is still good. What else may be the problem?

The problem is most likely the air temp control blend door is inop due to being stuck or the motor drive is defective or both.

Heated air still comes out of my vents even when the air is off

You might have a faulty water valve. The hot air in the car is supplied by the engine cooling system. As the engine works, it heats up and water is circulated through the system and kept at a cooling level by the radiator. However, this water is still hot, and by turning on the heat in the car, a valve is opened that allows the hot water to circulate through the heater core inside the car.
This core is in fact just a mini radiator, and air from the blower fan inside the car blows air through this mini radiator, thus supplying hot air in the car.
If you don't want hot air in the car, the heater control operates a valve that shuts off the hot water from the engine. If this valve is faulty, it will allow hot water to circulate through the system. Another possibility is that the cable operating the water valve might be maladjusted or the cable or the lever operating the cable is broken or faulty. It often happens that the outer part of the cables slip and the controls operate so-so but never well.
If the cables to the dashboard controls are not adjusted properly or have started slipping, it could also cause the fresh air vent to not close properly, and this will cause a flow of air even when the controls and the fan are turned to the off position.
You can remove the control panel from the dash and check the cables and controls, but it is a finicky job. Maybe you want to take the car to a mechanic?

I have a 2002 ford fiesta 1.3lx. When the engine is hot the coolant hoses are hard and obviously full of air. What are the possible causes of this.

As long as your not overheating and fans working properly, hard /firm hoses are normal. Cooling system builds pressure when hot, like a pressure cooker. The radiator cap maintains that pressure along with proper coolant mix to prevent boiling.

99 deville- engine bubbles over. Engine Temp. reads 255 but you can touch the engine with your hand. Also when climate control to set to 90 the compressor comes on and cold air blows inside from under the...

when there\'s air in the cooling system it can give a super hot reading because there;s no coolant where the temp sensor is located-when coolant passes over this super heated area it will boil -thus causing the boil over effect-with no coolant in the heater core it will not heat either-try adding coolant -run a little till it gets hot then shut off-make sure there\'x coolant in the over flow bottle as it cools back down it will suck coolant back into the system-don\'t let it run out or it will suck air back in-it will take a few heat and cooling cycles to get the air out. at the shop I work at we use a tool to suck all the air out of the system and then open a valve and the vacume draws the antifreeze back into the system. If you can\'t get the system to take antifreeze you may have a leaking head gasket that is pressurizing the system and blowing out the antifreeze-this could be diagnosed by a mechanic-cheers Denny

I have a 1999 Navigator. The heat will not get warm. It blows out cold air for about 20 minutes and then changes to

well the system is ok your blender doors might not be opening or you your heater controls board is bad if your temp gauge reads at half way mark

Heat wont work on drivers side of car.Only blows cold air even when control setting is up to 90 degrees. Passenger side works properly.

there is a flap inside the venting that directs the air. This vent can get stuck. It is controlled by a vacuum controlled actuator. It can be leaky or a hose is disconnected

BMW 325ci - Car cuts off on very hot days - Error code P00128

Check the following :

BMW Code PO128
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant

temperature (ECT) sensor reading, and the speed of the vehicle.

You will likely not notice any drivability problems other than the MIL illumination.
A code P0128 may mean that one or more of the following has happened:
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor
Past experience indicates that the most likely solution is to replace the thermostat. Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat

My 91 cadillac devile has no heat , just cool air blows even when

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.

if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.

Air conditioner

On my 90 Aerostar 3L, I had a similar problem, in that the front vent control, or blend door was not setup correctly and had to be adjusted. Somehow the choke type cable for temperature adjust, had slipped out of its holder at the door end, and was not allowing the blend door to close properly, and the outside air was not allowed to bypass the interior heater core, even thought the cooling core was lowering the air temp, but raising it again because it had to go through the heater core. Removing the top of the dash, and looking in from outside the windshield, and having someone operate the temp control will tell you if it's working properly, or needs adjustment. Alternately, if it's the manual control type, by quickly operating the temp control, you should here the blend door "thump" as you open and close it. There should be full travel in the control range, or if limited, the above problem applies, adjust at the blend door mechanism.
