Hello Kotankeiramo,

Great to hear that you have dug into the car a bit already. My recommendation would be to borrow or buy a multimeter. Or if you cant get your hands on one, use a test light. I would first test the power by where the harness plug meets the fan. You will need to have the car up to operating temp and the ignition on. However, you do not need the car running to do this test. Take the negative of the test wire and ground it somewhere. Then take the positive prong and try each pin in the wiring harness. If the light lights up then at least you have confirmed you have power. If there is no light, then you will want to trace the fan wire back. In order to do this effectively you will need a manual that shows the wiring schematics. Once you have the manual, you can test the same fan wire in numerous places. Once the test light glows in one of the places, you know the break or the problem with the wiring is after that point.

Good luck, wiring is one of the hardest things to diagnose. However, these pointers will put you on the right track.

If you did all that, you must have a broken wire or a plug that is not making good connection. you have to start tracing wires. Start with the temp. sensor on the engine, it works as a GROUND...
Hope this steers you in the right dirrection ??

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When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph.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 .

Where is the fuse for the cooling fan on a 94 cavalierz24


There is a fusible link which supplies power through the cooling fan relay . the fusible link you want, plus four others are located on the battery cable terminal on the starter solenoid ! the one you want is blue . There are two gray an two more colored rust . Do you know where the cooling fan relay is ? In the under hood fuse / relay box. On the side of the relay should be a diagram , or on the bottom it should be marked 30,87, 85,86 .If you find pin 30 at the relay socket an test with volt meter it should read battery voltage. If not take the fusible links off the starter an with ohm meter test fusible link end to pin 30 at relay socket .If open or shows OL you have a open circuit ! First I would try jumping battery power to the fan it self . These fans do ware out ! Radiator Cooling Fan Motor How to Test and Replace

Cooling fans are not coming on, what could be the problem?


Either the temp sensor is bad, or the relay is bad. or the fan motor is bad. Or you have a blown fuse.
Look for fuse first.... To test if fan motor is bad disconnect the connector to the fan and jumper it to the battery.if it spins it's good. the other two. use a component locator to find their location and replace. they are inexpensive. Temp sensor is in the cooling circuit (radiator...maybe next to thermostat) the relay will be in a fuse box under the hood.

2004 Pontiac Grand AM Cooling motors wont work.


Can you jumper the relay to make the fans run ? The computer sends a ground to the relay to power the fans when the coolant temp reaches 220 degrees or when the ac pressure reaches 200 psi on the high side.

I took my 2001 pontaic ateck to emissions and didn't pass it fail.due to the cooling fan 2 control curcuit what do I have to buy for this problem?


My guess would be a fan relay or it could be a short in that circuit somewhere.Replace the fan relay with one that has the same part number in the fuse box to see if its the relay that is faulty.

2000 grand caravan 3.8 Condenser fans not comming on with a/c ...fans do cycle with engine temp compressor is engauging and a/c is trying to work but gets hot fast with no ..... fan working


Check under the hood in the fuse/relay panel. Lift the cover and look inside the cover for the correct location for the fuse/relay controlling the cooling fans. Either the fuse will be blown or the relay is bad. Use a test light to check the fuse for power on both sides,if you have power on the fuse then the relay has gone bad. Hope this will help you.

Cooling fans will not come on


Hi,

Fan Relay switch is stuck open. This of course assumes your temperature sensor is working appropriately. Which I assumed since you seem to know that the engine is running hot.

Replace the fan relay switch. The relay switch is tripped when the temperature sensor tells the computer the engine is too hot.

Until you get the relay switch replaced, you can either by-pass the relay switch and directly connect the fans to the battery, or turn on your A/C ALL the time and use it at a minimum setting. This will keep the cooling fans running at all times.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
