Welcome. Post a few pics of the a/c
bracket areas. You may be missing a
spacer or have mis-matched brackets.

Are all the other belts aligned correctly?

Welcome to the site. You might consider placing a proper ad in the cars for sale section with a good description, location and some pictures.


For the A/C make sure your pulley alignment is correct and the belts are tight.

There are only a few things that will cause the belt to come off, wrong belt, wrong pulley, misalignment or the accessory that your powering is loose, and a loose belt.
