You probably have a front drive splined disconnect assembly that has gone bad. This assembly engages the front differential when 4WD is selected. Below is a figure of the item, it is on the passenger side of the differential area.

If you have the two ends of the wires then they will have the same colors and you will have to put them back together. add new piece of wire if needed and make sure that they are secure. you can use plastic insulated connectors or solder them back together and use shrink tube to weather proof, soldering is the best way for a good connection to any wiring job.

many seem to be able to clean that sensor
in case you mess it up , there are plenty of good cheap sensors at the wreckers/junk yards
you were never told a fault code so go some where else and have the fault codes read as it may not have even been that sensor at fault

this is a small leak in the evaporative emission control system.Most common cause is a loose or faulty gas cap but not always, Sometimes the check valve in the gas cap doesn't seat properly allowing the gas tank pressure to bleed down. The EVAP system needs to see a positive pressure in the tank.

Not legally. If you do it illegally, you'll get a check engine light on full time.

This sounds like the A/C switch got really hot at one point and melted the coating off some wires close to it and they've fused together. You'll have to pull the A/C switch to find out, there's no being able to see under the dash without pulling a lot of stuff out to get to it.

If you have replaced the blower motor and the blower resistor, you must have a failed blower switch. Also look for indications of overheated connectors/terminals. Blower motors draw high amperage when operation on high speed, many times melting the plastic connectors housing the spade terminals carrying the heavy current load.

Remove the thick plastic panel. If I recall, there is 1 torx screw (I could be wrong), but rest are clips, just pops off.
