Can't find AC switch

[PDXcamper13]

We recently bought a 1999 Thor Pinnacle 3050 in excellent condition, but we are having trouble with one issue. It has 2 air conditioners (on the roof), one in the front room & one in the bedroom in the rear of the RV. They can run on either shore power or with our generator. The user manual says that the switches to control this are in the bedroom closet on the back wall on the drivers side, but there are no switches there I found 1 switch on the left hand side of the night stand/closet to the right of the bed on the drivers side, but it is only 1 switch. The manual says the upper switch controls whether you are using shore power or the generator (you switch it up or down to select) and the lower switch beneath that controls which AC you are powering on. It says that you can only run 1 AC when using shore power, but if you turn on the generator you can run both AC's. We have only been able to get 1 (the one in the front room) to come on and run by using the thermostat setting. We can not find the switch that controls how to turn on the rear AC. We have looked & looked for it. Does anyone have this same model? Do you have any ideas about how this works or where to find the switch? Thanks.
