Hey guys it's been a while since I've been on here but I have this weird problem. I was using the ac on normal on the second lowest setting, then after a few hours into my drive the air output went down to the point where max ac on high blew no more air than normal ac on low. There was still cold air, I could hear the blower adjust to the low-hi settings and the different functions would still change such as vent, floor etc. Only the air volume changed, any thoughts? The ac was recently recharged and the upper hose assembly replaced. Now the weird thing is since it got so bad I turned it off and used the windows but now several hours later the air volume is back as it always was and should be!
