Cooling fan run continuesly

If your cooling fan runs continuously, check the fan relay or cooling fan temperature switch, or engine coolant temperature (ECT) sensor.

Both radiator cooling fans are running all the time ? Key off ? The cooling fan opperation
HOW they work
Cooling Fan Control
The engine cooling fan system consists of 2 cooling fans and 3 relays. The relays are powered by the battery positive voltage circuit and controlled by a switched ground from the powertrain control module (PCM).
During low speed operation, the PCM supplies the ground path for the low speed cooling fan relay through the low speed cooling fan relay control circuit. This energizes the cooling fan low relay coil, closes the relay contacts, and supplies battery positive voltage from the COOL FAN LO fuse through the cooling fan motor supply voltage circuit to the cooling fan. During high speed operation the PCM supplies the ground path for the cooling fan low relay through the low speed cooling fan relay control circuit. After a 3-second delay, the PCM supplies a ground path for the cooling fan high relay and the s/p cooling fan relay through the high speed fan relay control circuit.
The PCM commands the fan on under the following conditions:
• Engine coolant temperature exceeds approximately 98°C (208°F) Low Fan Speed
• Engine coolant temperature exceeds approximately 102°C (216°F) High Fan Speed
• A/C refrigerant pressure exceeds 361 kPa (52 psi) Low Fan Speed
• A/C refrigerant pressure exceeds 2100 kPa (300 psi) High Fan Speed
• When the engine coolant temperature exceeds 112°C (234°F) at key off, the fan high speed will run for up to 300 seconds. If within that time frame 102°C (216°F) is reached then fan speed will change from high to low speed. If within that time frame 99°C (210°F) is reached then fan speed will change from low to off.
The PCM commands the fan off under the following conditions:
• A/C is requested and engine speed exceeds 6,240 RPM
• Engine coolant temperature exceeds approximately 99°C (210°F) turns the cooling fans from low to off.

sounds like one of the relays are stuck closed .

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, command the Fans Low Speed ON and OFF.

Remove the cool fan LOW relay.
Did the cooling fans turn OFF?

This is normal. Cooling fans today are not turned by the fan belt but are run by an electric motor. The fan continues running until the coolant temperature is reduced

sounds like it could be a relay.

With everything plugged in and the fans running with the key off remove the cooling fan 1 fuse. Do they stop?

If they do not stop remove the cooling fan 2 fuse. Do they stop?

Many cooling systems are designed to let the cooling fan continue to run even after shutting down the engine...however, this should only last for a minute or so...your owners manual may help. If the fan never stops when turned off this is probably a faulty resistor...may need a good mechanic to confirm which...Hope this helps.

The fan runs for a short time, after ignition off, to continue to cool the hot engine.

It seems you are low in coolant. The temperature sensor has air to sense instead of liquid and temperature gauge will be low. Try to fill up with coolant but sometimes it's hard to get rid of air from the system. Have you changed the engine thermostat?
Hope it helps

boost vehicle but before you do that remove the fuse for the cooling fan till you get it to turn over once its running plug said fuse back in and get it to a shop to have them diagnose why the fan is on to long

EIther fuse, relay, fan motor itself, temp sensor, or bad wiring

you have a bad fan swtich in the block or the therostat housing its an easy fix
