2001 LXi chassis A/C

Does the large radiator fan run at full speed when you switch the chassis A/C on? Does the dash A/C fan run when you switch the A/C on? What are you referring to with HP and LP switches?
The fuse list show two fuses located in the lower front dash that are chassis A/C related. They are K39 and SK6.

I did have an issue with my chassis A/C where it just quit working. I finally found a loose butt splice wire connection under the dash. I did not have to remove much of the dash but was able to lay on the floor and stick my head up under the dash and move the wires around behind and near the chassis A/C switch and found the problem. I turned the ignition switch and the A/C switch on as I looked for loose wire connections and when I moved the wires around a certain way the dash A/C fan would come on and helped direct me to the loose connection.
