SOURCE: replacing a serpentine belt
Don't have a chart, video, or diagram available at the moment. Can offer you generic advice.
1.Somewhere in the middle of that serpentine belt, that is wrapped around all those pulleys, is an Idler tensioner Pulley. All this pulley does, is put tension on that serpentine belt. Usually located somewhere in the middle.
The Idler tensioner Pulley will be on a bracket. It will be on the end of the bracket. The bracket usually has a 1/2 inch square hole in it. This is used for a tool, that resembles a 1/2 inch breaker bar.
-> I, use a 1/2 inch breaker bar.
The 1/2 inch breaker bar is inserted into this square hole, and the bracket is pulled to one side.
This pulls the tensioner pulley away from the serpentine belt, allowing the belt to have slack, and then the belt is slipped off of one of those pulleys. Release the pressure slowly, remove the tool. Then the serpentine belt is removed all the way.
(The Idler tensioner pulley bracket, can only be moved in one direction, to take pressure off of the serpentine belt. The direction opposite, of it putting pressure on the serpentine belt.
The spring used to put pressure is Very strong. This is also an area, where you can easily slip, cutting your knuckles, or fingers, or hand, on sharp objects. Use caution, you may want to wear a glove, or gloves!)
Then the new serpentine belt is wound around the pulleys in the correct pattern, the Idler Tensioner Pulley is once again pulled to the side, and the last of the serpentine belt is slid into place. Then you slowly release the tensioner pulley, and it puts pressure on the serpentine belt once more.
Make sure the serpentine belt is in the grooves of the pulleys, and is wound around in the correct pattern.
On the car hood inside, or on the radiator support, or perhaps on the inner fender well, or in the Owners Manual, it should show the correct pattern for installing the serpentine belt.

you need to take glove box out. It's right behind three three 7mm bolts for the plastic piece that holds it in. two 10 mm nuts that hold it to the plastic piece. Should come right out with a little finessed force.

If there is only high speed fan, then replace the resistor assembly in the heater plenum. If there is no fan at all, then check the ground to the blower- the wire fails down in the fender well. Just run a new ground from a convenient spot to the motor's plug harness. Or it could just be a bad blower motor.

If you have the 3.8 ltr you just remove the belt, then the coolant hoses and then the bolts securing the pump to the block. Note: there is one long bolt in the pump that can be removed thru the access hole in the body side rail.
If you have a 4.1 or 4.5 ltr engine, you must first remove the A/C accumulator from its bracket, remove the right cross brace and the accessory drive belt. Remove the water pump pulley to pump bolts and then the pulley and lastly the bolts securing the pump to the block.
