1987 motorhome wimpy dash fan

I have a question concerning a 1987, 345 motor home dash fan. Mine is wheezing and has very little air out put no matter what speed; barely moves a tissue draped over the vents. Does anyone know if the original fans were undersized/underpowered? I bought this motor home last year and am working on fixing it up. Do I have an upgrade challenge here? Any thoughts or help is appreciated! Thanks!

I think you may have some blockage or a bad fan motor or a bad impeller. I recommend taking a deeper look to see if you have any unusual items in your vent system. A few years ago my daughter had a small fire when the fan ignited a mouse nest inside the vents that had fallen into the impeller housing.
