AIR CONDITIONER My air conditioner blows cool when the inside of the car is hot and sometimes it blows out hot air and all day long the clutch kicks on and off,the engine revs up and down constantly but when I start it in the morning it blows cold like it resets itself some times the air will be ice cold and then it blows warm,can someone help me out?

SOURCE: Air Conditioner Problem

I would use a multimeter and check if the voltage changes at the blower motor, as you turn up the blower speed on the controls. If it goes up, you need a blower motor. If not, the a/c amplifier.

SOURCE: Air conditioner works but not blowing out the vents

Check the air directing servo motors under the glove box. they are 2 black boxes about 3"x3". you have to clean the contacts of grease with contact cleaner spray or alcohol.

SOURCE: what can i do about air conditioner not blowing cold air

It could be the air conditioner pump or maybe the freon needs to be replaced in the air conditioning unit. You should definately bring it somewhere and have it looked at. You don't want to mess with freon at home. It has to be disposed of properly.
