I have a 1996 L/C. I have searched but I couldn't find anyone with the same symptoms I was having. While driving last week (and it was HOT) I got stuck in traffic. Well, the rig started to overheat. I cut the A/C off and it went back down. So, I cut it on again, because it was so HOT and it went back up after awhile. Once the traffic cleared (driving) I had no overheating issues. What could it be?
