I have a 1996, J30 and I am having problem with the air conditioner. I have had the air conditioner checked by a Nissan dealer (not a full check) and a air conditioner shop and they both indicate that the system is working ok. My problem is that it takes a long time to get cool in hot weather. My wife's Sentra gets cooler much faster. When the system finally cools the interior area of the car it stays cool. Could the problem be some place other than compressor and/or other components? Any advice would be appreciated.

use the recycle air button on the dash so cool from inside the cabin is used rather than fresh air which will be hot

i'd also get them to recharge the a/c....

i'd trade j30's with you in a heartbeat.... my a/c failed ... again....
