I purchased a used 1996 38 foot Newell RV and trying to figure out how the AC works. I turned on the generator and the AC worked, but the two back of the air vents had not air coming out and didn't appear to be any air coming out in the bedroom.  I didn't have it plugged in, so the generator is probably all that makes it the AC work.  The engine running makes the front AC work, but I don't think it makes the larger unit work.  Can anyone explain how the AC works with the front, verses the middle and back?

Thanks,
Jerry
