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When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph.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

I have a 94 plymouth sundance 6 cylinder the fan that cools he radiator is not working what is he problem


3liter 6cyl? (5 or 6 engines used, 2.2L up to 3.8)
in all cases (engine rad cooling fan) (seems not)
clutch fan failure? (if old mech. type fan) replace it.
if electric fan?
  1. bad control sensor.
  2. bad controller
  3. bad fan relay
  4. bad fan
  5. bad wire/ connections between them.

what we do is get it hot and see if fan works at the FSM stated trip temperature. (225F is a guess, ) alldata.com has this number too.
if the fan is dead, we check voltage the fan, 12v ? fan is dead.
0 volts? yes, then control is bad.
the work backwards from here, finding true cause. easy huh?
any cheap voltmeter made works .

the ECT is for the engine. EFI system. TBI?
but the Fsm states.
All models equipped with electric cooling fans use this sensor to control the cooling (radiator) fan operation.

i dont have the wiring set for this car.
try alldata.com and use that for fan wiring ,etc.

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.

2002 Lexus es300 electrical cooling fan shuts on and off with ac on


Hi Dennis, When the AC is selected an additional cooling fan should cut in to cool the additional requirements of the condenser radiator, mounted in front of the radiator cooling the engine. If the operation of the AC fan is intermittent the most probable cause is a defective control relay or a loose connection. The relays are easy to find, being in a housing usually marked on top of the outside. Regards John

2000 crown victoria overheats with ac off


The AC runs the fan that cools the AC condenser and the radiator. You may have a problem with the cooling fan for the engine only or its control circuit, this fan is controlled by the main computer in the car called the PCM, you need the dealer to perform a test that operates the cooling fan and delivers back fault codes for any problems found with its operation.

How a cooling fan should work


The cooling fan is thermostatically controlled and enerised once the radiator/engine temperature exceeds that of the thermostat controlling th the fan. If the fan is coming on prior to the engine reching the operational temperature, then either the thermostat is not functioning or ha been wired incorrectly into the system the radiator was changed.`

My car fan dont turn on when ac is off


Check the operation of the radiator cooling fan circuit:-
1) check fan control temperature sensor is ok,
2) check/replace the cooling fan control relay,
3) check supply fuse for cooling fan is ok.

Fan control relay


Quite often you'll find resistor on firewall, of passenger side under hood. 1-1/2"x3" block attached to firewall. In area of where heater hoses enter.
