2003 Dodge Caravan AC shot. Use shorter belt to elimate?

Yes, just take a piece of spring and wrap it around the a/c compressor and measure. Subtract that measurement from the belts current length and tell the local auto part store you need a belt that is shorter by (however many inches?) With the same amount of ribs as current belt. Trick is to get shorter belt to get tight enough, depends on how the belt is routed wether this will work or not also.
