Yes, usually in fuse panel under hood on drivers fender side.
Bad transfer case "encoder" motors and needing GM Auto-Trac II "blue" fluid in the transfer case are common AWD Bravada problems.

fuse box is underneath the steering wheel. You must lay on your back so that you can look upward from the floor of the driver's side. There is a wide rectangular covering you must remove to see the fuses.
Raise the vehicle off the ground, wiggle front tires left and right, excessive play tells you tie rods, up and down tells the wheel bearing condition, but have another set of eyes looking on the inside while wiggling tires, too see excessive play. Lower ball joint can be seen during this test. And make sure wheel spins freely, siezed brake calipers can make higher speeds shake too. Lastly look at centre drive shaft condition.

generally studs are press in thru the back of thr rotor. You need to remove the rotor and with a punch and hammer drive the broken piece out. Replacement studs are avaliable at any parts store.
there is a tsb for the telescoping motor and linkeage, also sometimes the ground wire to the horn gets torn from use, since it runs down the steering cloumn, or possibly just a fuse.
Check the Brake light Fuse the key cannot turn if the brakelight fuse is blown because the safety switch is parts of the brake light circuit. also check the brake light switch if the fuse is good and the brake lights do not work.
