Where is the fuse for cooling fans - 2006 Mercury Mountaineer

What engine does it have ?

Cooling Fan Control 2.0L
The engine cooling fan is a variable speed fan. The engine control module (ECM) controls the fan speed by sending a pulse width modulated (PWM) signal to the cooling fan control module. The cooling fan control module varies the voltage drop across the engine cooling fan motor in relation to the PWM signal. The cooling fan speed can be adjusted from 10 percent to 94 percent duty cycle. 94 percent is considered high speed fan.
Cooling Fan Control 2.2L or 2.4L
The engine cooling fan system consists of one cooling fan and one relay. Voltage is supplied to the relay through a fuse. The engine control module (ECM) controls the fan operation by grounding the cool fan relay control circuit. When the cool fan relay is energized, voltage is delivered to the cooling fan motor. The cooling fan motor is grounded through its own ground circuit.
When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph. This is to prevent the fan from cycling ON and OFF excessively at idle.


Just one speaker doesn't work ? Do you know how to do automotive electrical testing ? That's how to find both your problems . Speakes work by electrical inpluse's . The A/C radiator ( condenser ) fan also works by B+ voltage through a fuse an a relay , controlled by the engine electronic control module or PCM - powertrain control module . When you push the A/C turn on button , it sends a signal to the PCM . The PCM will then energize the radiator fan relay turning on the fan . Check fuse in the under hood fuse box , If the fuse is blown you have a electrical short , too much current flow . Plus if the PCM sees too much pressure in the A/C system it will not let the A/C work .

In the engine compartment fuse block. Look at positions 7 and 8. There should be a diagram under the lid.

there is 2 fuses that you have to check
one will be in the big fuse assembly in the engine bay, the other probably in the fuse assembly in the cab
If they prove ok then it is possible that the coolant temperature SENSOR is faulty and needs replacing
don't confuse it with the temperature sender which operates the temp gauge.

Well the code is for the circuit - the computer commands the relay to turn the fan on and it doesn't happen.
The computer provides the ground for the relay.
If you have replaced the relay and the fan and the fuse still blows, I would look for a problem in the harness between the fuse box and the fan, including the ground circuit for the fan.
The fuse for the cooling fan is usually a 30amp marked "cooling fan" in the fuse box in the engine compartment.
Do you know what the 25amp fuse that is blowing is for ?

there is fuse and a relay for the cooling fan.just turn ignition on and test all the fuses(some fuses will only work with the system on like headlights/tail lights).check the relay in the relay box(panel)under the hood.you may have a bad cooling fan,you don`t say why your checking the fuse.if you unplug the connector at the cooling fan and jumper a ground wire and power wire it should work.if not then you need a cooling fan motor or assembly.

check your sensor that controls the cooling fans.may need to be replaced.

most likely the cooling fan has a short in it. disconnect the connector on the fan. If it doesn't blow now its the fan motor. If it still blows you have a short from the fuse to the motor. What this means is the hot wire is touching bare metal somewhere

Could be the FAN MOTOR, COOLING FAN TURN ON SENSOR, even the PCM. There are 2 fuses . Also check fuse panel under hood in engine compartment
