All of the things that you have problems with are functions of the Body Control Module. Check those fuses.

Chevrolet Suburban (GMT900; 2007-2014) fuses and relays

Fuse box location. It is located on the side of the instrument panel, on the driver's side, behind the cover.

If those fuses are good, then you need an auto electrician armed with a professional grade scan tool computer. A bi-directional scan tool can check which part of the BCM is faulty.

Instrument panel fuse block .
Fuse Block - I/P
In the driver side of the I/P, in the door opening

u got 3 places it could b under dash on the sides of dash or under the hood next to battery

That info is on the owners manual, if you don't have the manual you can download one for free at the GM owners site by clicking HERE

Owners manual should lead to proper fuse,if not look inside fuse cover.

Find your fuse box, there is a fuse for the transfer case. Look in your owners manual for location of the fuse box and the fuse box diagram.

Please rate my help, thanks

Check owners manual. Check under hood fuse panel. Likely a blank spot where needs to be added.
