SOURCE: blend door heater all hot

No need to do that, behind the glove box is the blend door motor, it most often breaks the shaft of the blend door, which causes a costly fix, and it will break it again. There are sites that tell you how to remove the motor, drill a small hole and put a pin in the shaft so that the motor will still turn the broken connector, I did this and my blend door is still working 5 years later. I have heard stories of people paying up to $700.00 to have the original blend door replaced, and it breaks again.

SOURCE: 1998 ford f150- heat issue

There is no heater valve on a 1998 ford F-150. The hoses for the heater lead directly from the engine and go to the heater case. PS The heater doors are all vacuum controlled so you might wanna look under the dash for any lines that might be disconnected

SOURCE: Need to find and fix blend door on 2001 Audi A4 Quattro 2.8L

you would have to remove the dash. i would first check the auxilary water pump to make sure it's not leaking. if your car has electronic climate control turn the heat on low with the engine off the change the temperature and listen for an electric motor sound to see if the blend motor is working.

You just might have an air lock. Try bleeding the system from the heater hose at the firewall. Losen one hose a little, and at operating temp. open slightly to let air out. You will lose some coolant, but just refill the rad. Now, both hoses should get hot.

SOURCE: heater blows cold air. I have replaced thermostat,

Not an expert by any means, but i know my ranger.. I had a small leak at the top of my radiator that still cooled the engine but didnt have enough pressure to get to the heater. The heater hoses travel up over the engine and just were not gettin anything to my heater core. That or make sure the heater control valve is operating.

We've changed thermostats, flushed hoses, and got new heater core. 04 Dodge Durango still won't make heat. Engine takes forever to warm up.


Check the operation of the heater control valve, which you should find on the inlet hose to the heater core.

2000 ford taurus heater not working. What can be wrong?


It sounds very much like the heater control door (inside the heater box) is sticking in one position or the other. It's intended to direct air through either the AC's evaporator or the heater core, depending upon whether you want heat or cooling.

Assuming (highly likely) that the control door is vacuum-operated, you may have a vacuum leak anywhere from the engine to the heater box inside the passenger compartment, via the heater control unit.

No heat


You don't mention the make model and year of your car. A coworker has a old VW TDI with 230,000 miles and he had to replace the thermostat to get heat to work again.

Turn on power to heater & nothing but the power light comes on, please help


There's a heater core box where radiator coolant passes through. When you turn on the heater, the fan on the heater core box blows air through the core, then the air is heated up and it passes through the air ducts, which leads to the windshield defroster, the vents, or your feet depending on where you set the control. If you're not feeling heat, either the fan on the heater core box is not working, or there's restriction on the coolant hoses and hot coolant isn't passing through the heater core box. Remove and diagnose the heater core box to ascertain the coolant lines are not blocked and the fan is fully operational. If the heater core box is OK, then the hoses have restriction to prevent hot coolant from passing through the heater core box.

Hello My heat stopped working on my 98 milenia. I replaced the thermostat and flushed the heater core. Still no heat. Someone told me about the heater box. Looked for it under dash by taking out glove box...


Does the blower motor still work?
Lift the hood after the engine is at normal operating temperature, and feel the two heater hoses going from the engine into the firewall. Both should be hot if the coolant is circulating through the heater core. If they are, one of the inner doors in the heater box may not be operating. The doors are either cable operated or vacuum operated from your heater controls. One door in the box should be open when heat is desired to let the blower fan blow air across the heater core, and then to the vents where heat comes out. The heater box is usually rather large, under the middle of the dash. Have someone check your temperature blend door- I believe that is the one that may be at fault.
Now if only one of the heater hoses is hot, and the other is cool, the coolant is not circulating through the core. Look for an in-line water valve on one of the hoses. These also may be cable or vacuum operated from the heater control head. Not all vehicles have a valve, just some do.

Heater core 1991 grand marquis


This may be one of those where the entire dash has to come out to do the heater core.
But you only want to replace the core if it is plugged, or leaking. There is an easy way to tell if it is plugged: with the engine at normal operating temperature, and the control valve open so coolant will circulate, now feel both heater hoses. If core is blocked, only one hose will be hot. If core is circulating correctly, both hoses will be hot. If they are, you don't need to change out the core. One of your vacuum actuated doors is the problem, the blend door that lets air from the blower motor pass over and around the heater core.

96 camaro heater will not blow hot air


Yes, that would probably be the culprit. There is a blend door inside of the air box that switches from heat to cool. Either there is an obstruction keeping the door from moving, or the actuator that moves the door is not operating.
