A call to the dealership should be able to get you the official name but I would desribe them as the rear heater core lines. These lines basically supply heated engine coolant for the rear heat. A dealership parts dept can pull up a diagram of the vehicle based on the VIN number and give you the exact name and part number.

My truck wont blow out any hot air, just cold. i put a new radiator and thermostat in it. it is full of anti freeze


Try removing the Heater hoses from heater tubes(be careful not to break heater tubes off) then back flush heater core with garden hose(Don't use a lot of pressure). Jell from antifreeze builds up in the heater core and blocks the coolant flow. If it is easier, remove the heater hoses from the engine, that is safer. Back flush the heater from the hoses. To Back Flush (The hose coming from the water pump is the inlet)(Hose going to Manifold is outlet) Back flush outlet hose! To much water pressure may cause damage to heater core!!!! Do Not ues AIR!!!!

Water leaking from under glove compartment in


Is it all the time, it could be the heater core. if it's only when you run your a/c it's a plugged drain tube. it's located under the hood, by where the a/c goes into the fire wall. it's a black, soft rubber tube

1994 plymouth voyager heating problems. Just


After the car warms up feel the heater hoses that go into the fire wall from the motor both should be warm if only one is warm and the other is cool the heat valve that opens the flow of antifreeze to the heater core is not functioning locate the valve (either under dash in passenger compartment or in the egine compartment) it has a vacuum line going to it and it should have vacuum when the heat is on if not replace the vacuum line or valve itself. Back flush heater core and also be sure the level of antifreeze is up to the top low antifreeze will cause no heat to occur.

I have a 1992 Dodge Dakota. When the A/C is


V6 engine? If so, there is a small plastic vacuum tube that runs from the blend door actuator under the dash to a connector in the engine compartment. The tube goes thru the fire wall about 5 inches above the throttle cable (right under the heater core tubes). The tube runs about 10 inches (behind the intake manifold) to a vacuum tube that tee's off the right side of the intake.

My tube was broken....dealer and NAPA did not have a tube that small but had one that fit over it for a quick splice.
