Check the pollen/partical filter. if this gets blocked then it will restrict air flow

1998 Ford expedition motor not running hot enough


The engine is running at 210 you can be sure of that

Look at scan tool data

Your cabin heat issue may very well be several HVAC Blend
Door Vent Motors have failed
That data should be on the scan tool as well in enhanced data
& go to the hvac module

You can switch the heat or air flow to test if they are switching properly

1999 Oldsmobile slihouette heat doesn't get hot in the front


your heater core is not circulating..this could be because you have air trapped in your coolant system or your heater switch is not opening the valve to allow flow through your core. the front core is located higher than the radiator...so its hard to purge any air that gets trapped in it. personally...I installed a purge valve so I can expel any air from the higher parts of the cooling system....because I also had the same problem with my 2000 premier. but first try to purge your system of any air pockets by turning on your heater.....fan on high......let the vehicle warm up....add some distilled water or dexcool to your coolant tank.....rev engine to 2500rpm for a brief moment.....let idle for a moment and repeat 5 or six times....make sure to turn on the rear heater too at full fan when you do this. if this doesn't help....read up on your vehicle by means of chilton or other published repair manuals ...then check the engine heater switch for proper vacuum and electrical supply when your console control is on for heat (heater switches on the engine - located over each of the valve covers-one for front-one for back-with metallic tubing into side and out of bottom).....be careful...the heater switch on the engine will be very hot!! check relay in fuse box...check fuse in fuse box....check switch and vacuum supply to console control unit.....good luck and be careful....

Heater is very poor


Has the vehicle been run with anti-freeze its whole life? If not, then flush heater matrix.

With vehicle in cold state, disconnect heater matrix feed and return pipes from within engin bay. Turn the vehicle's internal temperature setting to hot. If the vehicle is fitted with climate control, then do this with the ignition in the 'on' position.

Take a garden hose and with low pressure first, try flushing the matrix. If the water pressure is not enough to flow through matrix at low to medium pressure, then a blockage is almost a certainty. If water does not flow at first, then try using a high pressure air-line to force air and any blockage material through the matrix and out of the exit pipe. You can also reverse the flow to blow or flush any dirt out of the other end.

Once all is clean and free flowing, reconnect and fill entire system with a 50-50 anti freeze-water solution.

If blockage cannot be resolved, then replace heater matrix.

If no blockage is present then continue to check heater control switches and wires.

Rear vents blow out hot air when a/c is on


Keep this principle in mind: Heat, flows INTO cold... When you hold an ice cube in your hand, your hand gets cold because the heat from your hand is flowing INTO the clod ice cube, NOT because the cold is flowing into your hand.

On this particular vehicle (like many modern vehicles), hot water from the engine flows through the heater core at all times, even when you have the A/C on or when you have nothing (A/C, heat or vent) on. The system uses a door that closes down over the air opening to the heater core to keep you from feeling warm/hot air when it is not desired. The reason(s) you feel that the vent air is warm even when the outside temperature is somewhat cool is/could be caused by the following:

First, although as mentioned above, the heater core is restricted from receiving air when you are not commanding heat by the control panel, the heater core ultimately ends up as warm as the engine temperature. This is generally somewhere around 200 degrees F. Because all the air coming out of your vent(s) must pass over the door that restricts air over the heater core, and because the heater core gets so hot, some of that heat is picked up by air passing over the hot door even though it is closed.

Second, the door that restricts airflow from passing over the heater core has a seal around it. After a period of time this rubber (or usually felt) seal deteriorates, allowing some air to actually pass over the heater core. Since the core is hot all the time, some of the air gets heat loaded, producing warmed air.

Third, the door is operated by (in the case of your vehicle) an electric motor which responds gradually/proportionately to the setting you select on the temperature dial. If the motor gets out of calibration (can happen from time to time), if the control head has a 'glitch' and sends an incorrect signal (chronically, usually), or if the electric motor (called an actuator and contains its own little electronic 'brain') becomes faulty, the door may not be closing completely. This symptom can also be caused by a problem with the door itself, where the door gets stuck due to warping of the plastic case, a foreign object preventing it from closing (usually a pen or toy dropped into a vent or defrost opening), or a broken or cracked door hinge.

Last, the vent intake opening, where the 'fresh' air comes into the car on the 'vent' setting, is located just below the windshield on the passenger side. This opening receives its air directly off of the sun-baked, engine-heated hood and because of this the air is never as cool as outside air even on a cooler night.

I hope this answers your question. Many domestic vehicle manufacturers have begun installing heater control valves on their vehicles once again as they nearly all used to have. Note that the fix for most everything I have mentioned here requires removal of the dash of the vehicle or replacement of the control head and therefore is in many cases not worth the investment if it is not an extreme problem (for example, unless the system is stuck on full heat in the middle of summer. Additionally, remember that, if you so desire, manual shutoff valves can be placed in the heater hose lines (please consult a qualified mechanic as water from a vehicle can and will scald and burn you!), allowing you to manually shut off the flow of water into the heater core, thus reducing some of the heat (Readers note that certain foreign vehicles REQUIRE water flow through the heater core at all times for engine cooling and are not candidates for this procedure!).

My 2003 ford focus heats up every once in a while I turn the heater on full blast it goes down to normal. Does anyone have any idea what maybe the problem


Something is wrong with the cooling system. You are using the heater and the heater fan as a secondary radiator and fan. The problem could be a temperature sensor on the engine or a burned out heater fan motor on the radiator/fan assembly. It could also be a fuse in the fan circuit. Your cooling system still has an adequate level of coolant or the heater trick would not work. Fix it soon. Eventually you will overheat the engine and loose your coolant.

Why is the heat blowing cold air but at a really high idle it blow hot air for little period of time.the temp of the engine is 195degrees. all the fan controls and the temp control is in the hot position


you could have a couple things going on. possible low coolant? most likely cause as i assume you have checked coolant level would be heater core restricted. to fix this you remove heater hoses and back flush heater core with water. if this does not do it you may have a water pump not circulating at idle but this usually comes with vehicle running hot at idle.

Heat lack of


9 times out of 10 on this old of vehicle its the heater core. If your car temp gauge is working and the car is heating up fine and the blower works then it is most likely your heater core. Not sure how hard it is on that car. SOme times it just under the dash takes about 30 mins but some cars you have to pull the dash out. The part alone is cheap. I would try logging onto autozone.com put in your car find the part (heater core) then look at the how to change section of auto zone.

Goodluck.
