Where is the cooling fan switch located on my 2005 malibu 3.5liter v6


Cooling fan switch ? The cooling fans (2) on that motor are controlled by three relays . A coolant temp. sensor gives temp info to the PCM - engine computer .
During high speed operation the PCM supplies the ground path for the cooling fan 1 relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the cooling fan 2 relay and the cooling fan S/P relay through the high speed cooling fan relay control circuit. This energizes the cooling fan 2 relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the cooling fan S/P relay coil is energized closing the relay contacts and provides battery positive voltage from the cool fan 2 fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have their own ground path. The result is a parallel circuit with both fans running at high speed.
The PCM commands Low Speed Fans on under the following conditions:
• Engine coolant temperature exceeds approximately 106°C (223°F).
• When A/C is requested and the ambient temperature is more than 50°C (122°F).
• A/C refrigerant pressure exceeds 1 310 kPa (190 psi).
• After the vehicle is shut off if the engine coolant temperature at key-off is more than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.
The PCM commands High Speed Fans on under the following conditions:
• Engine coolant temperature reaches 110°C (230°F).
• A/C refrigerant pressure exceeds 1 655 kPa (240 psi).
• When certain DTCs set .

Replaced thermostat and sending unit .check engine light went out .on incline have 3/4 gage warm, when level goes 1/4 on gage cold air,temp wont get hot.or 1/4 gage.could this be computer if so how to...


Not computer. You have air in the cooling system. Bubble is moving around. Park on an upward incline, take the radiator cap off, run the engine and keep the radiator full. Let it warm up and let the thermostat open (until you see flow in the radiator). Then fill to the brim and keep full until it stops going down. Also open any bleed ports you can find in the cooling system (there may not be any) and let any air out of them. Let the engine run and check for any bubbles that continue to come out. If bubbles continue to come up, you have a blown head gasket that is forming the bubble and causing the heater and temp gage issues. If bubbles do not come out, maybe you have fixed the problem by getting all the air out. Please let me know if you have any questions.

TEMP GUAGE JUST QUIT WORKING. COOLANT LEVEL IS FINE, HOSES ARE FINE. EVERYTHING IS COOL TO THE TOUCH. TEMP GUAGE READS BELOW COLD, YET ELECTRIC COOLING FAN COME ON WHEN ENGINE IS SHUT DOWN.


your gage has just gone out and needs to be replace. the computer control the fan. so as long as the temp sensor is connected to the engine it will work fine but you will not know the temp of your vehicle.

1999 Malibu Cooling fans don't come on. Country driving is fine. City driving and a few stop lights and it over heats. Temp Gauge works fine. If I un plug the sensor then fans come on but Tranny and Engine...


country driving at high speeds keep engine air cooled. but in city there is not much air to cool the engine. check the sensor for the fans. relay for fans must be ok, cause you said if you disconnect sensor then fans run. replace fan sensor. also make sure there is a proper amount of coolant in system. (do this first).

Have changed thermostat and head gasket has bbe


I recommend replacing the thermostat and before installing it, drill a small hole in the center of the flat seating surface to bypass coolant during warm up. This will help to gradually warm the engine and it can save you some damage to the engine if the thermostat sticks. Mine did the same thing which sounds like the thermostat is sticking closed. My temperature needle goes from 1/2 to 3/4 max which is ok. Turn on your a/c and it should engage the electric cooling fan which will also save your engine from overheating. You may have a defective fan clutch.

Replace coolant sensor an 2 cooling fan relays an fan motors an fans still wont come on when car reach certian temp


The cooling fans are designed to come on at about 215 degrees to 219 degrees,and I have seen them come on at 225 degrees,the engine is designed to average 232 degrees at the most,it may not be warm enough to come on the first time,but the thermostat,if stuck will prevent this also,and you need to bleed the air out of the cooling system.

Overheating on a 2001 malibu after thermostat has been replaced. We have replaced the thermostat, however the temp gage still registers over the 1/2 way mark.


Check the cooling fan, its sensor, the relay, the fuse. On most cars the fan is not needed on the highway, but engine overheats it it doesn't switch on inside the city. Also, clean the system with a special liquid according to the directions on the can and use coolant after that, water causes corrosion. While pouring/filling/cleaning, keep the heat switch on max heating to allw circulation via the heating radiator.
