Wheel bearing can be a big job without the correct tools. Better to pay a good mechanic.
Assuming your Burb is a 4X4, My first suggestion is get ALL of your wheels and tyres checked. Make sure they are inflated to the correct pressure, the tyres aren't damaged or badly worn and they are all balanced.
Next, jack up the car and REST IT ON AXLE STANDS. Your going to be shaking the car around!
DON'T JUST USE A JACK!!! It will fall off!
Once the wheels are off the ground, Spin the wheel by hand with a bit of force and listen to the wheel. A bad bearing will produce a 'gritty' sound. A brake disc noise will have more of a 'ring' to it.
Grab the wheel top and bottom, and push and pull in a rocking action. Do the same at the left and right positions. If you feel movement or here a 'clonk' noise get the whole suspension checked by a good mechanic. The above test shows if there's any play in the ball joints as well.
I would also suggest you get the drive shaft CV joints checked. Worn ones make noise when cornering.

Is the check engine light on? Are there any codes?

Check the grounding wires behind the front left tire. GM put the wiring directly behind the tire and there is a grounding bolt in the body. This usually gets corroded and nothing in the 4x4 system will work. Clean this up and apply some RTV Gasket sealer to help weather - proof it.

Automatic climate control or manual ? blower motor control processor , probably . or the blower motor , or the HVAC control module etc.... All these are just guesses , without testing the electrical circuits . Did you check the BLOWER fuse 40amp located in the under hood fuse / relay box And the HVAC /ECAS fuse 10amp in the under hood fuse box ? Plus HVAC I fuse 10amp located in the I/P fuse box .

These problems are usually caused by a faulty blend door actuator which controls the position of the air mixing door, and in vehicles with more than one air zone (passenger/driver, front/rear, etc.) there will be a door/actuator for each. These electric blend door actuators are self-calibrating - there is a feedback circuit (wiper type potentiometer) that tells your HVAC control the position of the door. It is not unusual for this potentiometer to wear causing loss of signal at various positions, which then will cause erratic movements of the door (if the circuit fails to open circuit or shorting, the door will default to fully open or closed - i.e. hot or cold air only).
