leak to rear air cond. how to repair.,shop said dont know where leak is. on 2001 Chevrolet Express 1500
I don't recommend trying this one yourself. Dual AC systems can be a nightmare to service, even in a shop. If you don't know exactly where the leak is, and you don't have any leak detection equipment, you're just asking for trouble.
