SOURCE: Radiator fan not working

Hi,

I am assuming that you are referring to the radiator fan. You need to verify that the fan motor is receiving 12V when it is supposed to be kicking in (engine hot) with a DVM (voltmeter) in its actual location. Having done this and likewise verifying that the ground is properly attached/connected, then your problem would be with the "clutch". Radiator fan clutch differs from aircon compressor clutch which is electrical and the transmission clutch which is mechanical. Most radiator auxiliary fans (not directly coupled) uses "silica oil". This oil has an inverse property, that is when hot it gets thicker and thus the rotation of the motor is transferred to the blades. There would be a filling hole adequately plug in or near the front of the fan assembly.

If your concern is not corrected by the addition of silica oil or if you can not measure 12V on the fan connector itself when it is supposed to kick in, then chances are your problem is electrically related. Some fan motor switching systems are coupled to the aircon switching.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: 2001 Grand Caravan - Radiator Fan Control Circuit Problem

The relay that is located right usually in the middle of the fans is stuck open.Take that off and take it to the nearest parts store and they should have it in stock.Its kind of a common problem.That relay is designed to finish cooling off the car before they shut off and they'll run with the keys out.If the relay is bad they'll keep on running till the battery is dead..

Check the fluid level in the radiator - after it cools down !

It sounds like you should replace the temperature sensor that controls the fan. This is usually located in the radiator and has electrical wires connected to it. Trace the wires from the radiator fan ( not the air conditioner fan!) to the sensor.

If the radiator is aluminum you may need special anti-freeze to prevent damage.

SOURCE: radiator cooling fan 30 amp. fuse keep blowing

The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps

SOURCE: 2003 Audi TT Quatro Coupe.

The main reason for the over heating of the audi tt is to do with the water pump. The propeller within the first type of water pumps is made of plastic. This was to prevent corrosion, however was never designed to last longer than 5 years. What you need to do is purchase the new style water pump. These new style water pumps have been designed with a metallic propellor which should resolve the overheating. Let us know how you get on.

2009 chevy hhr speakers don't work and a/c radiator fan won't come on


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 .

1994 pontiac sunbird radiator fan not working


Unplug the coolant fan & put battery voltage, directly to it

If it works, in either direction, then get a wiring diagram
& work on testing the control side of the circuit

You can check all fuses, but replacing a blown fuse,
is not a fix, for anything, that caused it to fail

Where is the fuse for the engine fan motor


there is a radiator fan control module on the drivers side near the dffront of the vehicle. There is also two fuse blocks under the hood, one on the right side in front of the battery and one on the left near the antilock brake controller. The fuse for the radiator fan should be in one of those blocks if not in the radiator fan module itself. If the fan fails to run, you might check the control module to see if it is malfunctioning. The owners manual will give you a reference on the fuse location as there are additional fuses under the dask in the Crossfire I believe.

Need to know where the fuse is for the fan by the radiator. I know where the fuse box is at because mercury sable has 2 boxes. Which one contains the fan fuse. My fan is not working and been replaced and...


You have a relay there are 2 speeds low speed and high speed this is controled by a cooling fan module if you changed fan and it does not work then you will need to check the fan module, first the relay its in the engine fuse junction box High speed is marked on the relay C1056 and low marked C1058, here is what you can do go to the high spped relay open thhe cover and expose the relay with key on collapse the relay does the fan come on? if it doesnt replace the fan module if it does you will still have to replace the fan module here is the location is at the radiator on the front (may be under shroud)

Car overheats, it has a new radiator but has had stop leak in it from bad radiator and fan does not run but works off the battery


recommend flush radiator, replace thermostat, then if the a/c works turn it on wait a couple of minutes and see if the cooling fan(s) come on if they don't then it may be that the fan control module in front of the battery is bad. also check the two large fuses in the fuse box in back of the battery

A/C fan and radiator fan aren't working


There should be a relay controlling them, check the relay comm for power.. You can connect the radiator fan driectly to the battery to prevent over heating. It has two wires, splice them and connect them to the battery via 2 other pieces of wire. In my opinion its very difficult to actually help with this one remotely since we would need to be on spot to test the circuit. I strongly suggest haveing an autoelectrican check this for you. YOu can connect the radiator fan directly to the battery to help you get there..

BTW the radiator contains a thermostat. this turns the fan on and off, of this is faulty you will have the problem you described. check the thermostat in the radiator.
