Chanses are it broke behind the gas tank wear it runs along the frame rail. You don't need a diagram to fix that, just unhook it at both ends and break it off or cut it off buy the tank and take the pieces with you to a auto parts store and they will match it up with new line, just take a tape measure and measure from the rear axel to the front block or perportioning valve, and don't worry about the piece behind the tank, just run the new line alongside the old one behind the tank unless you want to pull the tank out.

remove cover.take off back wheels and calipers (or drums).turn differential to where you see small bolt/pin (5/16) horizontally (same direction as axles)on right side of differential.remove bolt/pin.A large pin (about 5"long 3/4"diameter) should slide out differential with ease ( you may have to tap one side of the large pin).turn differential to completely remove large pin.turn differential so you can see in the view window.push each axles in (they'll go in about 1 1/2"each) You may hear one of the axle C-clips fall.If not use a small telescoping magnet to remove the C-clips from the axles through the differential window.pull each axle out about 10"so they are out of the diff.Now remove the cap bolts(4-5/8"bolts) and remove the caps(mark the caps so they go in excactly the way they came out.be careful the diff might fall out.If not you may have to use a long bar or 2x4 to wedge and pry the differential out. Have a basket/crate w/rags in it to catch the diff.TIP:If you are removing the ring gear from the diff, the bolts are left handed bolts meaning you have to turn them clockwise to loosen and counter clockwise to tighten ; )

Testimonial: "thank you helped ALOT perfect instructions "
Defrost is the default position. Is the control a autyomatic temperture control unit? ( you set the temp and select automatic) if it is the system is completely electronic. You push the buttons and the control still says defrost or can you select something else and the control shows it but it just keeps coming out the defrost? If the control changes and the air comes out the defrost anyway and the cheack engine light isn't on, then the problem can be blown fuses or an air door actoater not working. Does the dash emit a clicking sound? if it does with the covers off the bottom of the dash reach around touching the different pieces till you touch the idem that is clicking. this is an acutor motor, or blend door motor. they have gears in them that wear out and break the motors aren't repairable and you just replace the ofending motor. the door that is moves can be stuck. and may have to be freed up with blaster, WD40, or other rust buster till it moves easy. maybe after getting the door to move smoothly you can get the old motor to move the door wiithout having to install a new one.
