    the cooling fan is controled not by a switch but by a temp sensor if they are not running it could be the relay which is located in a junction box under the hood. the temp sensor is faulty or the fan is bad. a sure fire way to check is have the motor running open the hood and find the junction box. with the engine hot switch the engine cooloing fan relay with the a/c clutch relay if the fans turn on your relay was bad. if they do not turn on then your temp sensor maybe the culprit. also look for loose connections or broken wires to the fan and to the temp sensor.. hope this helps please rate this.......thanks

SOURCE: Radiator cooling fan doesn't come on.

first unplug the cooling fan at its plug and supply 12v to the fan if it doesnt run then replace if it does run follow the power wire to the thermal water switch usualy located at the bottom of the radiator.Use test light/probe to check that you have power into the switch and when engine is hot you should have power both in and out of the switch.if not replace thermal water switch.If that is working you will need to find out why you have no power to the switch.Check that your fuse and relay is working correctly.Sometimes just pulling out the relay and putting back in will make it work due to poor contact.Also try swapping relays with others in the same box near battery to identify if relay is faulty

Coolant temp 218 and smoking when I shut he car off

Engine is overheating. When the engine is cool, check coolant lever (remove radiator cap to check. If o.k. first repalce htermosatat and radiaotr cap. If problem continues, remove fan assy when engine is warm and feel the middle area of radiator (fins). If cold and the rest of the radiator is hot, you have a clogged radiator. Replalce it with a new one.

Also, there are two plastic "elbows" that couile coolant to the heater core (eventuallty). They are located in the area beneath the alternator. They are prone to leaking or outright breaking. Good preventive maintenace require them tobe be replaced The fix is to replace both of them with aluminum elbows, commonly available now in parts stores for that purpose. Don't replace them with new plastic ones! They will break just by looking at them!

1990 Buick LeSabre cooling fan sensor

It is located at the cover that the upper radiator hose connects to or near it in the manifold. See picture below of sensor.
The picture below is of the new style sensor, you must replace the connector, yours is the old discontinued style and will be round and you squeeze the connector it to release it. You will need a wiring connector upgrade as well to use the improved switch below..

2002 Buick Century continue to run hot although I have replaced the thermastat and the radiator and checked anifreeze levels - what's else could be wrong?

Turn your a/c on, both fans will start. The temperature switch is located on the intake behind the thermostat housing, but it isn't near as hard to replace.

When i turn on my air conditioner on my 2002 Buick LeSabre my fuse blows for the right fan. Do i assume the fan is bad? The left fan still works when the car gets hot.

My air conditioner on my Buick has a full charge of Freon and when it is hot out I don't get the cooling power in the cabin as I have it on low switch so when I put the switch on the high the Air doesn't change to cool the interior on high. I had the Freon tested and it still doesn't work properly and I wonder if there is a sensor that doesn't allow the system to cool properly?

Is there a fuse that runs the radiator fan in 1997 buick lasabre

there is a fuse aswell as a sensor switch in the radiator itself which when reaches certain temp activates fan to cool radiator, if radiator isnt getting all that hot or not at all there is a thermostat built into cooling system, generally to side above gearbox or to the front of engine, this could be stuck closed which will prevent water circulating, you can identify this part by looking for a dome shaped plastic or metal piece bolted to engine (generally two, one either side, and it will have an electrical sensor located in it or beside it, drain coolant, remove domed cover and there you will find thermostat, purchase replacement and refit making sure to clean all joining surfaces and use or apply proper gasket or liquid gasket to seal joint, filling cooling system is bit mor tricky, for this just google car make model with coolant filling procedure, dont forget to add anti freeze when refilling, this also acts as a summer coolant.

2001 buick lesabre is running slightly hot. i just replaced the thermostat and 2 elbow joints (sorry dont know what their called) and did a complete flush about a month ago

replacing the thermostat is exactly what i would have suggested for your vehicle for the overheating issue. try this,with the engine running at operating temperature,check to insure that the cooling fans coming on when the engines gaining temperature. your cooling fan may be going bad and not coming on when needed,in this case it may be a bad cooling fan sensor,or just a bad cooling fan altogether.with the engine running after you've driven the car until it gets warm,open the hood and look visually at the cooling fan to insure it's running{the engine fan} in front of your radiator. if it's not running {fan} check in the main fuse box under the hood for a bad engine fan relay 1st if no bad relay,then check for a bad engine fan motor.with the key switch in "off"position try to spin the engine fan manually by hand. if it does spin by hand it still may be a bad fan motor. or bad fan you have a check engine light on? if so you can have it code read at any auto zone or advance auto for free.this may be of great assistance to you if the check engine light is on. hope this helps and thank you for choosing

When i first start the car a message appears that says ENGINE COOLANT LOW. CHECK SOON. When you check the coolant(AFTER IT HAS COOLED) , it shows to be exactly where it is suspose to be. 1999 bUICK...

The low coolant switch may be stuck, and you may even have to replace it. Last time I replaced one it was in the radiator. Also make sure the level is good in the radiator when cool.

Radiator Fan Stays On

A simple test would involve disconnecting the fan switch while the fan is on. If the fan then stops the switch has failed. If the fan continues to run remove the relay , if the fan then stops the relay has failed.
Various inputs/outputs at the relay should be confirmed to be 100% certain something strange isn't going on.
Above all be careful of the fan itself , if it's running obviously but if it's not it could start during repair
