My 2007 Chevy Equinox's air conditioner only works when on inside air. When put on outside air it blows warm air. What is causing this?

Your cabin air filter may be severely clogged and not allowing any air flow from outside the vehicle.
Check your owners manual for replacement of this filter. The plastic fasteners that hold the shroud closed over it are reusable so be careful removing them.
Afterward, reprogram your air flow controls with the engine running and in park by turning A/C or heater on, pressing A/C and In/out air buttons simultaneously three times within 3 seconds and wait for the reset cycling to complete, about 30 seconds. [ref. 2005-2006 service manual]
After it completes, set your climate control to your desired setting.

SOURCE: 1991 camaro overheating

There are two freeze out plugs at the rear of the block (V8) and many v6 engines. If coolant is coming from where you say, likely they have failed. Unfortunately, the only way to reach them is to remove engine or transmission, It's rare that they fail because they are "protected " by the bellhousing, but can still rot from the inside out. There is no sealer known to man that will fix this. It's a shame that you need to do all that work for a pair of $2.00 plugs, but that's what needs to happen.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

GM AC units are among the very best as far as reliability goes, so no it is not typical, what is it doing, does the compressor run?

Heater on 2007 Suzuki vitara blowing warm air only

windows fogging up
well that takes 2 things working to do that 3 really
1: heat, you have heat. and blower works.
2: you need the dampers to work, to send a/c side air to the windshield. (it mixes heat and a/c flows)
3: the A.C must work it is the DEHUMIDIFIER PART.

i do not understand at all the sticking thing,
are you saying the controls are failing, ?

Air conditioner

Does the compressor run ? If yes, you would need to know what the high and low pressure readings are to proceed.
It could be a blend door problem under the dash, or something else.

check the air vent of passenger side for any obstruction and secondly keep your thermostat full towards cold side make sure the ventilator is fully closed position and rotate the air selection knob clockwise and anti clock wise two three times than set it at the required position mainly your air selector seems to be malfunctioning there is nothing wrong with the ac

My air conditioner compressor is cycling on and off. The car is a 2007 Pontiac G6. Only blowing warm air.

Usually if its "fast cycling" its low on freon which means you probably have a leak also. After adding the freon to the proper level the fast cycling should stop and you should have cold air in the low 50 degree range coming rom the vents. You can buy the cans of freon with the pressure gauges built into them so you can gauge how much to put in. It's based on outside air temperature. Follow the instructions carefully and you shouldn't have any issues.
