Guys, my wife '02 was having the same problem. The temp. display might have been reading 20 degrees when actually it was 90+ outside. I located a similar post on this same site before the crash. The guy suggested I replace the temp. sensor which was located near the top front of the radiator on the drivers side. I picked up a replacement sensor from the local dealer ($17.00 maybe) installed it about 5 minutes and WAH-LA. A/C's and temp. display are both working correctly. Good luck
