Go to the dealer Or MAybe Look Under the Hood For Diagram it will be ther

Sounds like the tensioner isn't working. It's easily replaced, but you need a special tool to re install the belt once you have changed tha part

I'm not sure if this is it or not

It is your AC clutch assembly or AC compressor.

turn the engine off and the serpentine belt will stall

remove the old belt. install teh new on in the reverse of how the original was removed.

There should be a belt tensioner.

The air conditioner runs in the winter time when you use the defrost function. This is to dry out the air so that you dont get foggy windows. Dont bypass it.

The diagram is usually on the bottom side of the hood or in fron of the radiator. look at all of the stickers under there.

You should be able to replace the belt and be running again. If you ran the engine for a long time or high RPM without the belt, you may have overheated it and caused additional problems - but you'd probably gotten a high temperature warning light if that were the case. The serpentine belt provides a way to transfer mechanical energy from the engine to the alternator, power steering pump, A/C condenser, smog pump, water pump, etc. Once that belt breaks - all of these devices cease to function (even though the engine is still running) and will cause the engine to stop eventually. If you broke a timing belt - that would be a different story - if the engine is an "interference" or a "zero tolerance" type. The valves inside the engine would be crushed by the pistons immediately - rendering the engine in need of some very expensive repairs or complete replacement. Timing belts generally need to be replaced every 50,000 - 60,000 miles (or 5 years - whichever happens first or as outlined in your owner's manual). Engines with timing chains do not require replacement as a regular maintenance item.Good luck!

have you tried replacing the belt?

Only at the dealer or auto shop that payes for the software program.Call the dealer and ask to talk to a tech i work at a ford dealer or i would look it up

usually it is on the chasis close to the battery.

It will depend on what engine

Very simply, there should be a spring-loaded "idler pulley" that keep tension in the belt, locate that and figure out how to release tension, they are all slightly different. Important!!- Make sure you make a diagram of how the belt is on there, so the new one can be threaded properly.
The idler puller usually is one that is just there, not driving an AC pump or alternator, power steering pump, etc. Look for a square hole in the idler pulley itself or it's bracket that a socket wrench driver can fit into. Then slightly put pressure on the socket wrench handle and the pulley should move without too much effort.

you can also use a 3/8" breaker bar on the belt tensioner.
make a sketch on how the belt is routed before you remove.

"HOW TO":
Standard Rules to Removal the Serpentine Belt with an Automatic Tensioner:
1. Find the Tensioner(s). (See Diagrams on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

Standard Rules for Installing the Serpentine Belt with an Automatic Tensioner:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them
