Can anyone tell me how to access the air output ducts, I think probably at the unit where they are attached. That's the most logical place to start. I have about 25 percent air flow on kitchen side of RV and you can feel air coming out around ceiling lights.
If you will turn on both fans when running one compressor at a time it will blow like crazy. Running only one fan while operating one ac unit will give you very poor air circulation.
