Follow your top radiator hose to the thermostat housing. There should be a sensor screwed into that with a wire harness attached to it. Unplug that and your fans should run. If they do not, check for power to the fans to rule out fan or relay.

The cooling fans may not be working be due to a bad thermal fan switch or fan relay.

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When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph.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

Which fuse goes to the cooling fan


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.

My 2002 Montana Van will over heat while idling, once I start driving the temperature gauge will come back to normal. I checked under the hood and the coolant in the reservoir is boiling and the electric...


These fans should turn on at about 220 degrees, give or take a couple, and then turn back off at about 210 degrees.Fans should also come on when engine is idling with the a/c on [provided the a/c works of course] If the fan[s] isn't running and the gauge is over about 3/4 of the way or will go all the way to the end then odds are your fan's aren't capable of working for some reason. The classic symptoms of a cooling fan not working are what you are describing: Cools fine at highway speeds, overheats at slow speeds. I would start by checking the cooling fan fuses located in the underhood fuse panel. I believe they are marked Cooling fan 1 and Cooling fan 2 and both should both be 30 amp fuses. If the fuses are good then you might have problems with the fan motors themselves. Hope this helps you get it working again!

Mercedes benz airconditioning


You might check the cooling fans on the condenser to see if they are running when the ac is on.If they are not check for blown fuse,or bad cooling fan relay.Do you notice if the ac cools better when running constantly,and the ac is not so cool when in traffic,stopping and going,and running slow?If so the cooling fan,or fans are not working.If the fan fuse and the relays check out fine,then replace the fan,or fans.If I can help any more please ask.roniecon@gmail.com
