X-2, you can do away with the whole fan assembly, throw it in the trash!
Replace the noisy, does not work that well, fan, with a "fantastic fan" The manual reversible one is under 100 dls. and you will love it! Fits right in the old 14X14 opening, and you already have power right there! Very easy to install! I loved them so much, I put one in my semi, and it was the best 79 dls. I ever spent! Rail!
