Question about 1994 Ford Escort
My heater wont warm up and the temp gauge doesn't move. We thought it may be a thermostat, so its been changed, but now don't know what to check? Help please? Hubby says one hose into heater core is warm, the other is cold. Also, may be unrelated, BUT it acts like it is starving for fuel at times as well.
Cooir its older than my escort ,now you havent stated if its diesel ofr petrol but anyway if one hose is hot and the other is cold then i suspect this older model has a valve/ tap operated by the cable from the control unit so check it out so see if it has one ,if not then disconnect the heater hoses ,collect the antifreeze and then try flushing the heater unit both directions and see if it passes water ?' then gat back to me via this posting and go from their

check the vaccum hoses on the passenger side under hood. I think that there are two hoses but it might be three. they get brittle and leak. but they move a little valve that you can move yourself just to see if heat works then. it is inline with the heater hoses I think. Bear with me though because it has been about 3-4 years ago when I figured this one out. it is definately a vaccum problem. there is also a set of vaccum hoses under passenger side of dash, several colors in it. might want to look there because sometimes kicked by peoples feet but money is on the ones inline with heater core. just move linkage and see if it gets hot air. Hope I helped and didnt confuse.

the dommed part of the T-stat goes up, it won't go in backwards as memory serves me, what u almost certainly have going on here is the Air temperature control electric bend door actuator s defective, and the door is stuck in the cold air position in the heating/ac duct, to replace this the dash must be removed from the car..

I don't know your vehicle, but does it have a blower door tucked in where the heater core is? If it DOES and that's broken then it could be the whole problem. It would mean it isn't switching from the A/C side of things to the heat side of them. Hope this helps, good luck! Also, just looked up the proper name for what I'm talking about, it's called a "blend door" and I think your car has one. It's what I would check, again, good luck!
