Paul, whoh big fella! lets think about this a sec ok? the control panel is simply a device that allows the oporator to deside the functions. Fan speed, temp adjustment,A/C or heat etc. the compressor is triggered by presure sensing switches in the freon lines. when you turn the control to A/C the power is sent to the freon switch this switch is forwarding the voltage to the A/C clutch on the compressor locking it into place. when the presure in the freon tube reaches its max point allowable the power is broken off at the switch and the clutch stop locking in and allows the air passing thru the core in the front of the radiator to cool the freon down lowering the presure. when it drops below a set presure the power is reconected at the switch and the freon flows again! this is called cycling. the problem here is you need to explain what function is failing in that control panel that you bypass.

Does it is going to easily come from the nicely suited vent ?? The doorways that direct the air pass interior the sprint are powered by skill of engine vacuum, & with the engine became off, there is not any vacuum. The doorways additionally are spring loaded, so they continuously return to an identical place whilst the engine is off. It takes a pair of seconds when you turn the vehicle on for the vacuum to construct sufficient rigidity to re-organize the doorways ... prevalent.
