Q: 98 automatic altima: rad fans wont kick on unless ac is on.

asked by on

radiator fans wont kick on unless the ac is turned on. I believe this is causing the car to overheat as it does so within a couple of minutes. the coolant system has been flushed. the temp sensor, sender, radiator, and thermostat have all been replaced. and the relays have been tested.

My car has 178000 miles.
My car has an automatic transmission.
