Troubleshooting the A/C system fuses

I think my AC doesn't work. Seems to just blow regular air. Hard to tell in the winter. What simple steps can I take in troubleshooting this?
Is this a good way to start? *If I find a problem here, great, but I am not going to be doing any big ticket AC repairs for a winter beater.

I turned on the cold engine, put on the blower, and turned it to the blue snowflake and cold air.
The electric fan did not come on. Engine was on for about 10-15 seconds.
I did hear a slight gurgling near the AC compressor after I shut off the motor. What can I deduce from this??

I read somewhere that fuse #10 in the kickpanel is "not used" in the 1998 manual,
yet people have plugged in a 15A fuse and suddenly their AC started working.
Have you heard this? Any truth to this??

Otherwise, here are the other fuses I think are involved with the AC.
Should I just replace the relays? What's the part number for these?

Engine Bay Fuse Box (PDC)
Radiator Fan Relay
AC Compressor Clutch Relay
Fuse #5 (Radiator Fan relay)
Fuse #9 AC Clutch Relay

Engine Bay Fuse Box (PDC)
