2005 2500HD air conditioner speed

When I set my air conditioner speed selection switch to 5 the HVAC system shuts off. It works fine at all setteings heat/AC on settings 1-4.

sounds like a "short" or the unit (AC) is not getting the signal. I haven't heard of this before, normally you lose the lower speeds first.

Might need a new switch you can get them and easily replace them

On GM's, the most common cause of a lost HVAC fan speed is the blower motor resistor.  Replace that, and it should work fine.  If it goes bad again, the blower motor is pulling too many amps, and that would need to be replaced as well.
