SOURCE: location of oil filter on a 2008 hyundai elantra

It is located under the alternator. If you are looking down at the engine, it is to the far left. If you are under the car it is to the far right before the oil pan.

sounds like your A/C compressor has failed.
Thermostat only controls coolant going through engine - not the refrigerant in the A/C system.
The bad compressor is causing extra load on the engine and making it heat up.
Unplug the compressor and take a test drive.
If it is unplugged - the clutch will not engage.
see if it heats up - and report back with your findings.

SOURCE: I have a 2006 Hyundai Tucson and the a/c will not

this is right, this uses motors,the selector motor is located on the driverside of the heater/ac box, there are a few of these motors you will need to test them by operating the controls until you spot the one that doesnt move,these motors are on the box one or two on passengerside and one or two more on the driveside, all depending on if you have daul zones or not good luck this can get tricky locating the right one and testing it.

Either the "MODE" control cable has come loose from the actuator pivot connection, or the MODE door inside the air box is broken.

My front defroster does not work but the back heater works.. if the van is running it will heat up but when you start driving the gage goes back to cold it blows cold but defroster wont work at all


Change the thermostat. Follow the top radiator hose to the engine. There is to T stat. That will get your heat back. on the defroster, it doesn't blow out air? doesn't switch vents? or just not get hot? Year make and model please.

Heat not blowing out of windshield vent


Put the defroster on and move your temp setting towards warm and youll feel it come out of there. Heat doesn't come through those vents on normal heater setting those are the defroster vents.

The heater/air conditioner fan diverter on my 2003 Elantra doesn't work. It only blows air from the bottom, not the A/C vents or the defroster. Advice?

The air blows but it don't heat like it suppose to nor do it allows the defroster to work. it a 2000 gmc jimmy 4-wheel drive someone says it may be the heating core


Sounds like a vacuum activated switch. Your engine vacuum is used to open and close little doors in your vents. If a hose is loose or disconnected or the electronic controls that tell the switch to let vacuum thru is not working, no air will reach your defroster vent at the windshield. Does the switch that controls Vent, Heat (sends to the floor), AC and MAX AC do anything at all? If they do, you may have a specific switch problem. If you switch from Vent to MAX AC the sound of the air flow should be much louder. If the switch isnt changing where the air blows, it is leading you to the problem. Either the switch is bad or the supply of vacuum to the switch is not there whether it is a loose vacuum hose or a disconnected one. Happens often when aftermarket stereos are installed and the installer disconnects something either by accident or forgets to reconnect it.

Getting enough heat from my used 2000 elantra


the light for air should come on with your defroster on, Be sure first your radiator is complete full while it is cold and also the coolant resivoir is at the correct level. Good luck, low coolant will definetely make it blow cold. Hope this helps, Merry Christmas
