It is a heater core not an evaporator. Core is locater against the firewall behind the dash. If the fluid level has gotten low recently it could have air trapped in the core. The return hose from the core is located on the driver side under the hood, under the cover on the cowl. The hose has a bleed hole located under the clamp. loosen the clamp, slide the hose back and expose the hole.. Fill the coolant bottle and run the engine. when you get a steady stream of coolant the air is out. If you still have no heat it could be an issue with the doors in the evap unit. Remove the glove box and check to see if the doors move when you use the controls. If all that is ok you have a plugged core.

1989 dodge w-150 overheating does a/c compressor have anything to do with problem?

Running the A/C does create a greater cooling load. Your freon pulls heat out of the car in the evaporator core, and releases it in the condenser that is located infront of the radiator making the air passing thru the radiator pre-heated. The compressor also puts a load on the engine that will make more heat.

Trying to put a new vapor canister in 95 grand Marquis.I got two lines running from engine to plug into canister but my connection has two plugs for my lines but on canister still a open hole nothing to...

Section 03-13: Evaporative Emissions 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DESCRIPTION AND OPERATION Evaporative Emission Canister Fuel vapor emitted through the evaporative emission valve (9B593) is stored in two evaporative emissions canisters (EVAP canister) (9D653) . I think you should have 2 engine vacuum lines, one for each canister.

Evaporative Emission Canister Purge Valve

Evaporative Emission Tube Shut Off Valve The evaporative emission tube shut off valve (9G332) is located in-line between the evaporative emission valve (9B593) and the evaporative emissions canister (EVAP canister) (9D653) . The evaporative emission tube shut off valve control valve is mounted on the fuel tank (9002) by an integral bracket. The evaporative emission tube shut off valve closes the flow path from the evaporative emission valve to the evaporative emissions canister during refueling to prevent overfilling of the fuel tank .

1998 5.7 ltrCheyene fan system blockage. Fan

Sounds like a plugged evaporator core. The blower motor in located under the dash on the passenger side, behind the glove box. Some models have a trim molding which will unbolt for access. Once you have removed the blower motor, look inside the duct work and see if dirt, paper, ect has plugged the evaporator core. Sometimes a small vacuum cleaner will be able to **** out the debris.

Heater core replacement 2002 grand cherokee V 6

Youu didn't provide a lot of information about your problem. Jeep G Cherokee s are experiencing a lot of heating problems but the root cause is not formely related to the heater core. However, assuming that the diagnostic has been confirmed and that the job has to be done it has to be considered as a major job. The center console, the steering, the complete dash have to be removed just to access the casing where the heater core, the A/C evaporator, the fan and different doors (blending and recirculate) components are located. Let's say 9 to 12 labour time by a technician, plus parts.

So my advise is make sur your problem is really the heater core. By instance, if you have no heating it could be related to right or left or both of your blending doors being defective.

Hope it will help

2002 nissan maxima AC and heat will not work at the same time

There is a module called a power module located engine side of firewall almost at the upper center. It drops down into the evaporator case to keep it cool. Sometimes covered over with a black plastic cover. 2 electrical plugs connect to it. It varies the fan speeds depending on in car temperature. Should see 2 blue wire tie things retaining the electrical plugs to it.
