The condenser fan does come on when the a/c clicks on - but the radiator fan does not.
Yesterday I tried to duplicate the overheat problem while parked, I just left it in park and watched the temp start to rise with the a/c on. Then I checked the radiator fan and it was not on -- it works I guess because sometimes I see it turn on - is it the fan sw? If so where is located. I don't know if the radiator fan and the condenser fan are supposed to come on together when the a/c is on.
BUT I did notice that even when the a/c is off it still overheats. - Sorry to mention that but I just discovered that yesterday. I swapped the relays in the box that turn the fan on and still same problem. The only thing I did not replace is the fan sw. Also there is another switch that looks like the fan sw. In the front of the engine. But that might be for something else.
