whats the best thing to do to get my A/C running good? it blows but its not very strong and its not cold air or hot air. it just seems to be air.. like on vent or something. any advice/opinions? thanks in advance..

 

Is the compressor clutch engaging? If not, its not circulating refrigerant, so just blowing outside air(like the vent). Causes can be the relay for the clutch being defective or low or no refrigerant.
