Chrysler Pacifica Cooling Fan
 

I have a 2006 Pacifica. I took it to get a tie rod put on and the day after my car started to overheat. I realized the fan wasn't coming on. I have replaced the fan relay, the radiator, the fuse, the cooling temperature sensor and the thermostat and the fan still won't come on unless it is hooked to the battery. Unsure wht to do now
