A/C fan is a secondary fan.

The fans are working properly and the T-stat checks out fine. I think it was just me being paranoid. Maybe I should shut the AC down in town when the temp is 95+. The check gauges light never flashed and I never had steam so I don't think I have a problem except my driving habits.

I have had that problem with mine from the begining! AC on in town ran 240-260...NOT GOOD! Put in a 180* t-stat and a dryer duct for more air flow, and problem solved. Don't wait to late though, because i fryed my tranny fluid before changing the stat. A bunch of stock bonnevilles of these years have had a heat problem with ac. Also if you get the new PCM from intense you can turn the fans on at 200 instead of 220, and they stay on for 30 sec after you shut it off! Cost about $250 though! Replace the thermostat though and you wont heat!!!!! Get a failsafe 180 stat from autozone for $10, these work best, because if they get stuck..they stick open...keeping you cool!
