Heater blend door won't stop cycling

My heat control hasn't worked for some time. As long as I can have AC I didn't really care. While working the control lever the blend door, or something behind the dash, started "flapping" and stops sometimes and other times it just flaps endlessly. How do you gain access to this area behind the dash?

Temperature control does not work


There is a mode door in those that controls where the air comes out and there is a blend door that controls the temp of the air. If you cant change from hot to cold then the problem is the blend door. You should be able to see it behind the glove box. The glove box door has stoppers on it that you can remove so that it drops out of the way, then you can see the plenum that holds the heater core and the fan. There is also a filter in the plenum for in cabin air filtration. Change the temp settings and see if any of the levers on the plenum move. If they move then the blend door is either loose or broken off inside the plenum.

'94 Ford Taurus-No Heat?


Good point. Solving it will probably take more time than money.
Thermostats and heater cores do not work one day and stop the next. If your engine warms up normally and doesn't overheat, the gauge reads normally, engine is at normal operating temperature after about 10-15 minutes ...all these point to a good thermostat. It is working right and should not be a problem.
To check the heater core, wait till engine is at normal operating temperature. Turn heat setting to high, then feel both heater hoses-both should be hot. If both are hot the core is circulating coolant and is not a problem. If only one is hot (which would be the inlet hose) the core is not circulating-could be an air block or the core is plugged up and will need replacing.
If heater core and thermostat are good, then it probably is the temperature blend door in the heater case. The door actuator is probably vacuum controlled. I don't know how difficult it is to troubleshoot on your Taurus, but check if vacuum controls are working right from the dash controls, check if the blend door is stuck, is broken, or if the vacuum control is working to open and close the blend door. When you want heat, the blend door should let blower air pass across the heater core.
From the engine you will have a single vacuum hose that goes through the firewall into the dash to the heater/AC controls. There, a pod like device can rout the vacuum signal to various doors on the heater case.
Good luck.

Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Heater on nissan almera


That noise is the heater and AC air temperature control electric blend door motor trying to move a duct door that is sticking due to heat warping. You will need to remove the entire dash assembly and replace the blend door. This door is located between the AC core and the heater core and "blends" the air from each (hot from heater core and cold from AC core) to give the desired air temperature,.

My car heater works fine sometimes and other times no heat comes out until I hit a bump in the road and it works.


this problem is most commonly caused by either a sticky air temp control blend door or a defective blend door electric actuator, this door controls the air temp at the heater/AC oulets.
