We bought my son an 09 Altima SL coupe last year. The car had zero issues until a/c compressor recently went out. A local shop changed the compressor and a couple lines that had apparently been pinched somehow. Air conditioner performed perfectly (extremely cold) until first long trip. As the trip went on (30 minutes on, interstate driving) the cabin became warmer and warmer. Eventually the fan would barely blow even when on highest setting. Oddly, the fan still made plenty of noise, just not much air coming out. So, perhaps the air was cold, just not enough of it.
Brought the vehicle back to the shop, and they could not recreate the issue. Car was fine for a couple weeks of only short trips. On the next long trip, it happened again. This time I was with my son. We drove a while in a muggy car before trying this. I shut the a/c button off and adjusted the temp to 85. It took a few minutes for the air to get to hot and as it got hotter the fan blew harder. We then switched it back to a/c and lowered temp. It blew ice cold for the last 30 minutes of our trip.
Any ideas?
