    Check the 40 amp fusible link in underhood fuse box. You probably need to replace it. This master fuse controls those various functions. You may also have one in the cabin fuse box so check that as well. Good luck!

    I have exactly the same problem on my 03 Tahoe. I checked all the fuses and swapped breakers and they are all OK. Others have suggested a reprogramming of the Body Control Module or the Door Control Module. Maybe it is a software glitch as it seems a lot of people experiencing the same problem on one isde or the other.
