    only thing left is coolant flow thru core. are the hoses hot where they meet the core at the firewall? If not, your core may be clogged. Try backflush by taking hoses off and attach a garden hose to lower port using a hose and clamps

The part you need is a dealer stocking part. There is an electric motor that turns heater core on and off. It's located under the dash to the left of the glove box. Some disassembly required. The part will cost about $120 to $180. part number is #MR958603. I saved money by purchasing it on line. It is a stocking part at most Mitsubishi dealers. Once you pull the glove box out and remove the bottom half of the dash all the way across, you should be able to gain access to the motor to replace it. Caution: if you do not put everything back in correctly and tie/tape it all back down carefully in the correct places you will have lots of under the dash noises when you are done.

There is also an actuator for temp control. It moves doors in the duct work for heat and for cold air. that is the one that needs replacing. the one you are talking about just moves airflow positions.

Does the blower fan work and is the engine coolant full?
If your vehichle is not overheating, then you can also likely rule out a sticking thermostat.

Asside from those obvious causes, it would most likely be that the vacume-actuated heater switch on your coolant lines, going to the heater core is stuck (or there may be a vacume leak on the line that activates that switch). This happens as they wear or get clogged from age, and they should be replaced about every 5 to 7 years anyway. On most Ford vehichles, it's a fairly inexpensive part and very easy to replace. In fact, if I were having the same issue, I'd switch out that part whether it was the cause or not, simply to rule it out and keep it reasonably new and working. Also check for any possible vacume leaks on the vacume line that controls that switch.

Cant find the door acuator switch on 2001 monte

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.

The fan works, air conditioning works, but the air wont heat up(knob turns to hot on thermostat). is it a vacuum hose problem, and how do we get to it?

The most common cause of this in the Ranger and the Explorer is that a part called the air temeperature control blend door acuator or the blend door shaft that the electric actuator moves has broken, this door is what shuttles between the heater core and the AC core and provides either heated or cooled air, or a blend of the two hot and cold air streams.

What causes heat not to work in 1989 sentra? the thermostat was replaced and so were fuses

will try to help. is your radiator full and has been winterized? as far as,has it had antifreeze put into radiator? low coolant in radiator is#1 problem for no heat. you've replaced the thermostat, so that's new. good thing. no leaks?is the heater fan blowing? when you turn the heat up,do you hear something in the dash moving? or do you feel resistance in the slider[the red zone] when turning the heater on,on the dash? if not, the acuator,or heater control valve on the dash may be bad. if the heater fan;s not coming on, are you sure you checked all fuses?even the one's under the hood in the black box? hope this helps and thank you for choosing if you need further assistance,please repost your question and an expert will be happy to assist!

My heater only blows out cold air. When I first turn it on it blows out hot air for about 3 seconds then it turns to cold air. I have flushed the system twice, and that didn't work so I changed the...

check the vacuum lines going to the h-vac (under the dash where the blower motor is) make sure there are no vacuum leaks if there are no leaks start checking the blend door acuators firts locate all of them then start looking for the one that closes and opens the cold and hot blend door. turn the nob to heat and the other one to panel (not a/c panel just air) then if your not sure which one controls the hot and cold blend door start checking to see which acuator has vucuum going to them if there is vucmuum going to them but the acuator does not move replace it.but if it does compress take the rod lose from the blend door and see if the door in side the box is broken. if is not replace the climate controler on the dash. i hope this helps.
