Under the steering wheel, you need to remove the panel under steering wheel.
I have similar problem with my 1990 318i and found that the aux fan not working (if you connect power directly - it works) because the thermal switch circuitry is faulty. I have then bipassed the thermal siwitches and made it so that the fan should run when ac is on. It worked for some time but then the fan being faulty itself is drawing too much current and blowing the fuse.
how do you remove the fan clutch on a 1992 318i 1.8 liter?

The 1997 Acura Integra fan relay switch is located inside of the fuse box. The fan relay switch will be in the third column, second from the top.

Under the hood in the fuse block you will see a large black block. This is the heater blower fuse.
