Windchaser pacr93 it just stopped blowing cold air and stopped venting hot air like the compressor or something is not engaging correctly. It sounds like its trying to engage but then it doesent so the fans/blowers/motor is slowing than speeding than slowing over and over again, any idea whats wrong with it?

SOURCE: fan motor slow on a/c

If the fan motor has a capicator it could be bad. A bad cap will pull the motor down. If there is no cap then the motor beatings could be going bad. this can be checked by matching the motor amps with the rated amps on the unit information tag.

Check for a frozen cooling coil. Turn the fan to the on position at the thermostat and the cooling to off. Your cooling coil may be iced over. Allow it to run in the fan only mode until the coil has had a chance to defrost. At the outside unit you may see the large line is frosted. This is the visual indication for a frozen coil. When you return the A/C to cooling use it with the fan on while in the cooling mode.

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: Heater on driver-side blows barely warm air other vents blow cold

the most probabale cause of this would be a disfunctional hear core if you replace your heater your heater will more than likley work the the way it's supposed to

SOURCE: ac not blowing cold air.

Sounds like the compressor has failed.
