Need to check the blower motor resistor and the blower motor itself. They should be located under the passenger side dash.

Not sure if you need to replace the entire lens assembly or just a hid bulb. The Assembly is easy to remove with only 3 10mm bolts. The bulbs are all accessible from the back but the drivers side is a bit snug if you have larger hands. Most guys pull the assembly to give easy access to everything. Any of this is definitely a DIY that should take under 20 minutes both sides. If you need to replace bulbs buy a pair and replace both sides not just one. When you update this with what needs to be done then we can get your proper instructions

it could be the transfer case motor. sometimes they can be resyncronized by switching in and out of the low range 5x. If you don't hear the motor switching then most likely the motor is bad

it is on the right side of the engine. It is hidden under the engine ecover and cold air ducting on that side. To get it off is two bolts and one connector. You will need to take the serpintine belt off as well. I don't have a image for that right now but either find one thata shows where the belt goes or make a drawings before you take it off. That way replacing the alternator is not a headache and should take less than an hour.
