Driver seat not working 2008 HD 2500
 

Hi I just bought truck, 2008 silvarado 2500 HD, Seems as if the driver seat has NO adjustment, The fuse n left side / fuse box, was fine the center circuit breaker (25) DEEP fuse/circuit was a little flaky, so ordered a new one. In mean time I thought I could switch the "25" fuse from the "power rear window" (which I do not have)slot, up one to the "driver seat circuit" spot. When this was done, there was still NO POWER, on any of the driver seat functions of seat. I am really lost on what I can do next??? I can't seem to find any wiring schematics on this truck to find out what wires are what, especially in the harnesses that are under seat. Any suggestions would be appreciated! Thank you
