bbrendal : you can replace the clutch and field coil on your compressor with out loosing your r-12...if you have the tools and can do it while its on the truck, your field coil may be weak and not holding the clutch like it should....now do you know how old your compressor is, find what a clutch and field coil cost, and see what a new after market rotory compressor cost that fits your brackets , you should be able to replace your compressor for less than $200.00....my new sandon was $125.00....the old A-6 compressor took a lot of h.p to turn it, and the new rotory compressor turn easier...but cool good and you can still use r-12 or 134a.....
