Car only blow luke warm air into cab?

I have taken out the electric accuator and when I plug it in and turn the key on it moves from open to close both ways with no problem, then after that when you try to change from hot to cold the unit will not move at all. I tried replacing the accuator and a new one doesn't even move when I plug it in. Any help would be appreciated

If your heater is electric control then you will have accuators that open/close then vents when you change the temp settings. If this is the case you will need to determine what accuator is out to replace it. Most vehicles will use the same accuator, meaning, if your car has 3 accuators then most likely all 3 will be the same, but not in all cases.

I have a 2003 Ford F-250 Fx4. The heater blows out fine but will not heat up until the truck is over 40mph. What is the problem?


the themostat has to open so you have to warm the car up first so thats normal but if you mean that the heaters dosnt work even when the trucks warmed up untill 40 mph than it may be an open outside vent accuator may be bad..and it dosent close till speed build up presser against it

Heater is blowing luke warm air. does not get any hotter


Quite a few idea's come to mind.
1) Thermostat is stuck open, causing the engine to run cool.
2) The vacuum valve that opens and closes the air "flap" is stuck open, allowing cool air in all the time.
3) The vacuum valve that opens and closes the line that feeds the heater core isn't opening all the way.

Mercedes 190E heater blowing just luke warm air


there should be an electric water pump exclusively for the heater. on these 201 body cars it should be under the hood, on the passenger side,near the fender well. when the heater is engadged, this pymp should turn on pushing the hot water into the heater core. if these are not working, it will obstruct the water flow.

Defrost blows cold air


Sounds like you have a plenum door that is not opening when you go into defrost mode. You will have to check all your vacuum hoses and switching valves under the dash to see which one is not working. Hope this helps.
