Ruge, i dont think so. Check ground wires on battery and on radiator core support and on engine block. Mono, try replacing the flasher unit. If that doesnt help you, the switch is probably bad

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When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph.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

1995 chevy lumina what turns a radiator fans on


All electric..thermostatic switches. When the coolant gets too hot a switch is tripped that fires up the fans. There is a mechanical valve too, it directs hot coolant away from engine.

My 1995 camry is running hot. I have replaced the thermostat, hoses & radiator cap, but its still overheating when I stop for about 3 to 5 minutes. Any suggestions plz?


If your model has electric cooling fans they may not be turning on or reaching high speed. The fans work to boost cooling capacity when the regular water pump is not enough.

There are Relays for the fans and they get the signal to turn on from temperature sensors or setting a dash control.

If all switches work, fans, etc. then your Radiator or block may be clogged.

1995 chevy lumina sensor went out and fan wont turn


How did you determine that the sensor failed. Did the check engine light come on? When you say that the fan won't turn, do you mean that it won't turn on and run or that you can't physically turn it by hand. To determine this, disconnect the electrical connector to the fan and try to turn it by hand. It should turn easily. If it doesn't then it must be replaced. If it does then reconnect the electrical connector to the fan and try to operate it by disconnecting the temperature sensor lead and placing a jumper wire between the terminals of the harness. turn the AC control to AC/MAX and turn the ignition key to on. If the fan runs then the problem is the sensor. If it doesn't then check the fan control relay and any related fuses. WARNING : Use extreme caution when testing the fan circuit. Never attempt to turn the fan with the electrical connector in place. The fan can operate at any time even if the engine is off.

Electrical diagrams for brake lights and turn signals, for a 1995 chevy lumina


In a Lumina if the brake lights quit working but the upper one in the rear window still works or your tun signals flash weakly or a different speeds the turn signal switch needs replaced. I will cure the problem. Not to hard a job, but does require removing the steering wheel and air bag assembly.

Are both radiator fans suppose to come on together?


I found this forum site and from what I can discern, both fans should be running once engine temperature sensor turns them on. Can you switch wiring from 1 fan to the other? This would let you know whether you have a faulty motor or relay. Maybe you can pick up some tips too.

Radiator fan stays on all the time and car runs rough


The fan relay may be malfunctioning (the fan relay is what actually switches the fan on and off and gets its signal from the ECM, which in turn gets its signal from the temp sensor) testing/replacing the relay and temp sensor would be the best thing to start with,... unless you notice any additional (non factory) wire attached to the power wires to the fan.  Sometimes folks, in an attmpt to fix  an overheating or fan relay problem, attach a ignition switched positive lead from the fusebox or other switched source to the positive poer lead on the fan,.. making the fan run whenever the ignition is switched on.
