Dealer is quoting possibly 3gs

I turn the selector to either 4 auto, 4 hi, or 4 lo. The indicator light will continually flash and I hear a click like the transfer case is shifting but will not actually engage. I have tried in park, in neutral, slowly rolling and even at moderate speed (30mph).

It only lights up for a short time if you tap on the dash board.Do you know which fuse to change or is it a short?

When I purchased my 2007 GMC Yukon the passenger power seat would adjust back and forth; however, it would not adjust up and down. Thank you.

I replaced the starter already. It's not the battery or alternates. It's not turning over.

My harness passenger side underneath the battery area, shorted out, caused a fire, by igniting the plastic wheel well. The slow burning fire lasted an hour before someone noticed and called the fire department, who extinguished the fire. Several wiring harnesses in that area, wheel well and break-line destroyed. Lucky I didn't lose the whole vehicle. Maybe there are reports about fires in the engine compartment like mine also, is there?
I'd like to have some info as I soon will need to contact insurance company and dealership to get this fixed. Thanks

We need to know if there is a recall with this and how do we fix it

I does it every time I open the drivers door, I am not using the keypad to open the rear hatch. It just does it on its own. Please help!
