1st Window is easy you've got that solved
2nd the Resistor only controlls fan speed, if it's bad the blower will only work on certain speeds, no speeds, but always work on 5 as the blower bypasses the resistor all together
3rd im not too familiar with, although unless your having issues with your guage cluster or something of the sort not lighting up at night, try scanning it again and getting the full detailed description
4th I would say this one can be a few different things, check your brakes first, if they are good, then its a possibility it's your hub bearings being worn as they will create the same symptom they are easy enough to swap out.
