Fuses - No Fuse. I THINK it is powered by the Body Control Module and you can't remove that or disconnect power..

Either in the trunk on the drivers side behind the carpet. Or under the dash in front on the console. I work on to many different makes to remember.

rear compartment under carpet

There is a power box located in the trunk for onstar. Other than possible bad wiring, I'd check the box and all connections to it.

The first thing i would do is to unplug the fan and see it it is coroaded or not. Then i would run the car and wait untill it warmed up and put a light tester on the hot wire to the fan and the other end to a ground. If the light comes on the the problem is with your fan motor and not the relay. The relay is locaded in the fuse pannel under the hood. When you open it , it will tell you which one it is.

OnStar fuse is on the inside cabin fuse box, 10amo fuse. Fuse box is usually located on drivers side, near your left knee.

The Vehicle interface unit VIU and the Vehicle control unit VCU and the receiver is located behind the glove box in the passenger footwell. the onstar button is located int he overhead console. the modules are vin specific so they cant be swapped out without GM. you can remove them I have a 02 and since its no longer supported by onstar i yanked out the VIU and VCU and the cell phone receiver. then took the GPS transponder off the front driver side of the windshield and the rear attenna off the back glass and got an overhead console minus onstar and put it up. They unplug and cause no problems The fuse is fuse 32. The actual guts of the Onstar system is in the frontmost overhead compartment that is between the driver and passenger seats. However, if the option wasn't purchased you'll just have an extra slot for sunglasses.
