Sounds like the engine coolant temperature sensor.

These have a variable speed radiator fan. I'd check the radiator fan controller --they're a known problem.

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When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph.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

94 camry xle 6cyl changed thermostat changed hydraulic fan new radiator cap and new coolent and it still overheats once the guage reaches a little over half way then it gets hot real fast what do i do


Softly418 had this problem...........

This could result from a thermostat which is stuck closed (but you have a new one), or a failed coolant temp sensor not allowing the radiator fans to run when they should, but I think you have a blown head gasket. Overheating is a classic sign of combustion gases getting into the coolant. The pressure also forces it out of the overflow.

Warm up your engine a little, about half, and remove the radiator cap by putting a towel over it first. Then let the engine keep idling until hot while you look down the filler neck into the radiator......carefully.

If you see white bubbles like dry ice, that is a failed head gasket. If not, have a mechanic do a test for combustion gas in the coolant with a gadget like this

Engine light came on and car is over heating. Took it to auto zone and was told it's the fan relay. Its a 2003 PT Cruiser, Turbo. I opened the fuse box under hood. There are 3 spots for relays in there...


Turbo Radiator Fan

The radiator cooling fan is a variable speed electric motor driven fan. The radiator fan assembly includes an electric motor, fan blade, and a support shroud that is attached to the radiator. The radiator fan is serviced as an assembly (fan motor/fan/shroud).

The variable speed radiator fan is controlled by the Powertrain Control Module (PCM) by way of a Pulse Width Modulated (PWM) signal. The duty cycle ranges from 30% for low speed operation then ramps-up to 100% for high-speed operation. This fan control system provides infinitely variable fan speeds, allowing for improved fan noise, A/C performance, better engine cooling, and additional vehicle power.

To control radiator fan operation, the PCM looks at inputs from:

Engine coolant temperature
A/C pressure transducer
Ambient temperature
Vehicle speed
Transmission oil temperature (automatic transmission only

HENCE CHECK THE PCM

Camry overheating


Possible stuck thermostat(located front LH side below the alternator), or faulty water pump(inside timing cover)!! The fan has no connectors because its hydraulic driver through the power steering pump(V-6 models only). You may disconnect the switch on the powersteering pump to test the fan.....with the switch unplugged rev the motor to 2200RPM and you should hear the fan increase in speed. If not check the filter (LH side of the radiator) its black with rubber tubing on each side. Check also power steering fluid. Hopefully this helps!!

The radiator fan running slowly


This is a variable fan that changes speed with engine conditions. Some actually don't operate at all when the engine is cool. Older fans ran continuously and wasted engine power.

Radiator fan on my 1994 toyota camry


there are actually 3 temp sensors. 1 is on the top of the engine that goes to temp gauge in dash has 1 wire. next to it is a 3 wire sensor for engine control and choke. on the bottom of the radiator next to the hose is a 2 wire sensor. loosen all 3 but leave connected. get engine hot past halfway point on dash gauge. with ac off disconnect 1 sensor at time. start with 2 wire under radiator. it takes the most abuse. fan will come on when you disconnect broken sensor. 2sensor must agree for fan to stay on till engine cools when turned off. note this is solution i used after verifying fuses, fuseable links and relays worked.WOO HOO! make sure you check both the fuse box under hood and fuse boxleft side of steering wheel my ECU fuse was inside my bros was outside.ECU B on my car goes to nothing and is under hood. Had it confused with ECU on wiring diagram.DOH!

AC fan motors


simple fix for now solution
grease the fans bearings sounds like there over do for this kind of maintenance
also could be a speed variable cooling relay
example a vehicle reaches certain speeds the fans shut off alowing the air outside to come inside to keep vehicle cool with out using much power
