Changed battery and reset codes and lack of power reduce power power steering issues continue I need to know what else can be wrong. Checked all fuses and relays. Check thermostat and temperature sensor wiring connectors still no change.

Coming fans will not turn on when the truck is running. Only when the truck is off. I've replaced the coolant temp sensor and all cooling fan relays and fuses. It's making the computer think it's over heating so the truck acts like it's over heating even though it isn't.
