upnorth15, the wire removal that was suggested won't impact the fan starting up with the AC switched to on or at least it shouldn't.... the system should work normally.... in "actual normal wiring", typically only 4 wires are used and fan control is NOT wired. Those wires are used only for "direct" control of the fan. If you disconnect them at the thermostat as suggested, then the switches for fan control (specifically) will do nothing. If the fan still operates as in your problem, then the issue is likely somewhere else... as suggested by hornnumb2, in the control box area maybe.
