2013 R/T. Got A/C issue that has my mechanic and myself stumped. Operates cold for about 20 to 30 minutes then you feel the power of the air from the front vents start to decrease until next too no air coming out of the front vents. You can hear the blower blowing normally just no air from the vents and can't feel air from the upper or lower vents either. Found out if you turn the A/C off but keep the blower on high after about a minute the pressure from the front vents comes back and the cycle starts over again. Very strange. Any thoughts would be most appreciated.
