My a/c system has been acting erratic lately. At first, nice cool air blowing through the vents, then after reaching temp it doesnt seem to return properly unless I screw with all of the buttons for a while. Air-flow will divert to dashboard and floorboad returns, or not at all at times. Also do not have warm air for heat. Any suggestions are appreciated.

Are you getting any sort of codes? If you are getting an intermittent B337 code, it is for the HVAC (Heating Ventilation and Air Conditioning) system loss of communication with the BCM. You could have a short between the climate control programmer or the BCM.
