When I press the button to change the speed of the fan it does nothing, and continues to blow at one speed and it is just about equivalent to the speed of the slow option...any ideas why? Also it will run...


Is it new? There may something wrong with the electronic circuit board not allowing other fan speeds. Try unplugging it for a while and try again. There is a temp sensing bulb somewhere on unit most likely on front where hot/warm air from space enters unit. Make sure you are not recycling cold conditioned air back onto sensing bulb.

Air conditioning blows hot and cold air


You will need to know if the compressor is working when it blows hot air to proceed. It could be an electrical problem, a blend door problem, or the a/c clutch on the compressor.

Well there are a number of things that can be wrong here. You may have a coolant leak, You may have electrical problems or a bad compressor. There is no easy way to figure this one out.
