Cooling fans are fairly simple. Check the fuses first. There is a thermal switch located on the radiator. Disconnect and jump the two wires. If the fans don't come on, check to see you are getting power to the fans. There are two relays that turn the fans on and off. Highly unilkely they would both fail at the same time. I'm betting on the thermal switch being bad.

Why the cooling fan fuse has no power/fuse is good?


The cooling fan is controlled by the PCM via a couple of relays. Try swapping the cooling fan relays and see if the fan starts to work. If that doesn't work than you will likely need a scan tool to determine if there is a fan request from the PCM.

Code P0481


Both radiator fan relay's ????? There are three relay's !
DTC P0481Cooling Fan Relay 2 Control Circuit
Circuit Description
Output Driver Modules (ODMs) are used by the PCM to turn on many of the current-driven devices that are needed to control various engine and Transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which the PCM is commanding on. DTC P0481set indicates an improper voltage level has been detected, which controls the Cool Fan 2 and Cool Fan 3 Relays.

Check cooling fan maxifuse 15 amp. This fuse supply's B+ voltage too cool fan relay's 2 & 3 control side . The PCM supply's a ground to energize these two relay's , the PCM is not seeing the correct voltage that it should be . The fuse could be the problem , an open circuit , the transistor or driver as GM calls it output driver module . The number 1 relay is working fine , with A/C on # 1 relay is turned on or energized by the PCM for low speed operation .
There is a good video on youtube on how this three relay cooling fan system works an how to trouble shoot .

When i crank my 91 celica gts up the fan cooling the radiator does not come on. what could be the problem and how much would it cost me to get it fixed?


The fans only come on when the engine reaches normal operating temperature, and/or when the air conditioning is turned on. If the fan is not working it could be a fuse, relay, temperature sensor, a bad fan motor or damaged wiring between any of these components. To repair it can cost anything from a few dollars for a fuse or relay, up to over $100 for a new fan motor (depending on brand) plus about an hours labor if you don't plan on installing it yourself.

Does a 95 cutlass supreme have a fuse for the cooling fans or only the relays. I dont see a fuse for the cooling fans. Neither fan is coming on, Ive jumped the fans they both work, Ive changed out 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.
