It sounds like the compressor is kicking off and on to much, this is caused by a slightly low ac charge, have the system tested.

What is an engine cooling fan...can you feel it come through the ac vents?


The engine cooling fan is located on the front of the engine between the radiator and the engine block. You do not feel it through the ac vents.

2002 nissan altima When I turn on the ac my car feels like it doesn't have the same power While driving it feels like the car has hesitation or slipping When the ac is turned off the power from the engine...


That could be several things, or nothing at all. The ac compressor does use some horsepower when it is being used. But the engine should have enough power to overcome the load.
So the engine performance may be a little weak, or the compressor may be using more power than it should.
Does the engine feel normal when pulling hills or at take-off ?

It is normal for the engine to run hotter when using AC, if it is overheating you may have a slipping belt.

Problem could be a number of things:
  1. worn or slick drive belt - drive belt slips and with AC on could cause stalling
  2. bad MAF (mass air flow) sensor
  3. dirty EGR valve
  4. bad TPS (Throttle Position Sensor) - controls idling speeds under all conditions ie. engine is cold, warm, running with AC on

When the temperature outside is hot and I'm running the air, the temperature gauge starts moving into the hot zone. If I turn off the air, it goes back to normal. I've had it worked on several...


make sure that the coils, ( the ac radiator ) are clean , blow them out with an air hose if you can get a hold of one, also, make sure the ac fan is coming on, it may start , but the sensor may be bad allowing it to turn off too soon , a normal rise in heat is expected when using the AC but if it is too hot you should feel the motor start to run rough, if its running fine, and the temp does move back to normal when the ac is turned off, and a qualified mechanic has checked it, your probably ok, you could have a sensitive gauge, , If the normal range of the gauge moves to hot and back during normal driving without the ac on, that would show the thermostat is also working

Kia over heats when air is on only


your AC cooling fan is not working properly, most vehicle has two fans, one for the radiator and another for AC, both work in sync with one another; if one cooling fan only working it does not produce enough cooling for both radiator and condenser at the same time; by running ac you producing more heat and its cant cool the engine fast enough with one fan so your engine is overheating when running AC. The temperature sensor could be faulty and need to be replace or your fan motor can also be faulty. Check the fuse first and the relay make sure they are not burn out. sensor cost about 30 bucks get it new, relay 35-40 new used 5 bucks at junk yard, fan get it from a junk yard for 25-30 bucks, new will run over 100 bucks. don't run the air and overheat your motor, it can damage your engine or may blow your radiator. if you do run ac watch the temp very closely, don't let temperature get into the red.

1997 Civic Lx idles rough and low especially with AC on


It's the extra load on your engine when AC compressor kicks on, and it draws engine rpm down. Your fuel injection system has what is called an "idle air control valve", that is supposed to overcome that and adjust idle up & down automatically as needed according to engine load conditions. I'd say it needs replacement, unfortunately it's a little more expensive than most & will run you about $165. Before you do, if you do, make sure all connections & any hoses running to it are in good shape no cracks, on tight & clean, as that can also cause part to malfunction.
