AC went out after I replaced my battery.
perhaps you bumped one of the delicate aluminum refrigerant tubes in the process, and let out all the refrigerant....I would go and have the system pressure tested should at least be 12-14 pounds coolant pressure on the expansion side~ there are Epoxy kits to mend the refrigerant line, but they don't last~ ....change out the leaking piece with brand new...your a/c repairman will know what to do~
