Because there are many entertainment system options for this vehicle, your only option will be to get the wiring diagrams from a service manual or a site such as Alldatadiy.com and look up your particular system option.

The Trainer 24 Power Window Troubleshooting Test the electrical circuit ! Could be the window regulator ! Or check the wiring inside the rubber boot that comes from the body to the door . Over time these wire can break .

There are a few things that would cause this problem.
The first and most common would be the switch itself is bad. the next would be a bad 4wheel drive encoder motor, this is the motor on the transfer case that is used to operate the 4wheel drive. The last would be the 4 wheel drive module.
You will need to do some testing, if the four wheel drive is working and goes in and out of 4 wheel drive then i would say it the switch. if it does not work correctly it may still be the switch or one of the components i listed above.I have enclosed a wiring diagram, you will need to do some testing to check system, first make sure all fuses are good. the fuses that operate the 4wd are listed on diagram, it will also tell you the location of each part. you will need to test front axle actuator and selector motor and switch, you will need a test light and a meter. hope this is helpful, good day.

You should be able to find this in the Haynes manual for your model. Many car parts stores carry these books.

The first troubleshooting steps you can do without a diagram. Inspect the fan wiring to make sure it isn't damaged. In particular, check the connectors for corrosion. Also (with the battery disconnected or the engine cold), check the fans to make sure you don't have a pair with bad bearings. They should spin easily with no slop or wobble in the bearings (worn bearings can bind up).

The hard shell is glued on and is not removal, sorry have been asked this question a few times, the glass shop heats the adhesive and rolls the edge of the fabric out of the way to replace glass, that to requires special tools and sealers, this is not a do at home job.

The Auto Parts stores here carry Chilton's or Haynes repair manuals that usually have wiring diagrams in the back.

crank sensor is bad

I assume all lamps are tested to be ok.
1) Check fuse A11 in trunk (10A) is ok,
2) Check turn flash enable relay 'F' in trunk is operated when vehicle Ign on,
3) Check +12V is present on Lt Blu wire on turn flasher module (LHS steering column) when Ign on,
4) if no fault found during above checks, operation of the turn switch should be checked
