Re: A/C Cab Question
In your pic that shows the leaking area, I would pull away the cab insulation for a closer look. I think you will find the leak is where two panels meet, I have two cabs that have the same leak. This seam was spot welded at the factory as the cab was built, the they smeared a bunch of seam sealer on it waterproof the seam. On my affected cab, it appears that area held water over the years and eventually rusted through. The worst one I have (basically junk due to this and other areas of rust) has about a 2" x 1/2" hole rusted along this seam. Sorry if this is the case, because it will be a huge PITA to repair.
