I have a 1999 Dodge Ram Sport 5.2L and the AC does not work, when I turn the AC on the temperature does not change so can you tell me what I can do to figure out this problem?

Your welcome your also going to have to check the high and low pressures also. Does your temp door work also?

I think the temp door works because when I turn the temp knob I can hear something that sounds like it's moving.

Also if the engine is hot when selecting the hot temp the heater will operate like normal. Then when going to the blue setting the temp will blow alot cooler.

I was checking to make sure the temp door works and when the truck is hot and I select the hot temp it blows hot air and when I select the cold temp the temperature changes to cold air does this mean it is working correctly? I also was checking to see if the center of the AC compressor is turning when the AC is turned on and it is not turning, does this mean the compressor has failed or is there something else I can do to try to get it working?
