Hey! This just happened to me today. I was at the stop light andtraffic was heavy and I was basically parked, and sinceit was VERY hot out side (40c, 105f) and I notice that my car started to over heat! The gauge went from 90 and was on its way to the first next line (100). So I turn off the A/Cand after a few minthe car temp wentback to 90!I turn on theAC again and sure enough the tempstarts to rise again. So Istart to drive normallywith the A/C and the temperature drops back to 90. So now its about 9pm (much cooler now27c. 80f)and I test my car I leave it on and parkedwithout theA/Cfor 15min and the gauge is on 90 all thetime. Then I turn on the A/C and let itsit for 15 min - 20 min and the temperature starts to rise again!At which point I turn off the A/C and sure enough the tempdrops to normal after about 5min.
