my wifes 2007 tucson water temp is heating up as well as the a/c when she stops. Now im thinking its the fan since thats the only thing (that i can think of) that the two systems have in common. I wouldnt think its the t-stat sionce the a/c heats up as well. Only problem is by the time i check the car the fan is on and the water temp and a/c is fine.

can i get some opinions on where to look. maybe im missing some item that the two systems share that if went bad both would heat up.

thanks
