So, like Wes said, did they both fail at the same time or not? It would be the rarest of rare things to happen for both motors to fail at the same time. I would also guess there is a relay that controls the rear windows. I did some digging and I did find easily that there are fuse box and relay box PDF's out there but when I look thru them I see left and right window circuit breakers but I can't find anything, so far, that is specific for rear windows.
We recommend that you put all your rig(s) info in your signature so we all don’t have to guess at year, make, model, engine size, trans, rear axle locker…….etc. While you may have posted pertinent info in your first post, you may forget to do it again and the info is needed by us anyway. Makes it way easier on all members that attempt to help, to have that info right up front. It is also recommended that you take a pic of your RPO codes, on the inside cover of the glove box, and post that image in your signature. All this info will greatly help those that will try to help with a problem.
If there is any other info, like upgrades, mods or recent mechanical/maintenance work done, that would be helpful in any post as well. Too many times a question is asked by the poster and after about 10 responses we find out that the poster has done recent work to attempt to fix the problem or work that was done that SEEMS not related to the problem.
