SOURCE: radiator fans won't come on
Hey I had the same problem with my 95 olds cutlass supreme. First i checked that the fans were receiving power by testing the voltage. Then I noticed that they were recieving voltage just not coming on. When the engine temp got pretty high, they finally came on, another words the gauge could be broken or the engine just does not tell the fans to come on until it has reached a high temp. So i started the vechicle, left it in park and gave it gas until the temp guage read very high, it reached like 230 to 250 then the fans came on. Try getting the temp up there and then see if the fans come on an dlet me know at [email protected]
SOURCE: where is and what does the cooling system fan
The fan temperature sensor,(Fan switch), is activated by the cooling systems coolant. Activated by it's temperature.
It's located under the hood, passenger side, upper engine area, below the alternator, and mounted in the intake manifold.
My money, is on the fan temperature sensor being bad.
The fan switch will usually be cylindrical shaped, the bottom is made of brass, and the top has a black insulator material, with a rubber type plug on top. The plug will have two wires coming out, going into the engine wiring harness. One wire is Black, one wire is Yellow.
The fan relay is located in a relay panel. I can't tell you at present, whether it's in a black plastic box, that you remove a cover to access it, or the relay is exposed. If it's in a plastic box, under the cover it should state what each relay is for, and where they are located inside the box.
The relay panel is under the hood, on the passenger side, front engine area, on the passenger side of the radiator.

check coolant first .if all good .hot wire the fan make sure the electric fan motor is operating.if runs when hot wire.replace the relay and coolant temperature sensor.if fan dont run.when hot wire.replace the fan motor.

Your Problem Can VERY WELL BE with the Temp Sensor, As It Is the First in This Electrucal Circut . it Waits for 210-230 Degree Engine temp and Gives that Sygnal to the ECM then ECM Grounds out the Cooling FAN RELAY To Turn ON the FANS and the Temp Sensor is Usualy THE #1 Culpret Closley in front of the RELAY.
There are 2 Sensors On this Vehicle The One You Replaced and One Located At Trans Side of
Engine Closer to Front of Vehicle At the Head ,Thereis a 2 wire Plug On it and This Sensor Goes to the ECT witch CONTROLS COOLING FAN RELAY. Hope this Helps and if you Need A Diagram For this It Must be Emailed as FixYa Does NOT Support Large Picture Files. My Email Add. Is MY

SOURCE: Does a 95 cutlass supreme have a fuse for the
There are three fuses and two relays for your coolant fan. They should all be in your underhood fuse box. They may not be marked "coolant fan", so check them all, (2) 60 amp , (1) 20 amp, (1) 15 amp. If all the fuses are good, you may have a bad fan switch (temp sensor). It tells the fan when to turn on, follow the wire from the fan motor to find it.
