Same happened to me, fans weren't turning on even after i got new fan motor's. The thermostat sensor wasn't connecting with the thermostat properly... so i got a plastic tie and adjusted the thermostat sensor in a position that made contact and therefore activating the fans (definitely ghetto rigged)
My engine overheats if I run the a/c while driving at highway speeds. No problems at highway speed without a/c. No problems in town with a/c.
