These air pumps have been filling with water for years but the design was only recently changed a couple years back. The check valve is the source of all the problems that require replacement of the A.I.R. Pump and blown fuses. If you do not replace it the pump could fail again as quickly as one day. Parts warranties, unfortunately, do not cover failures caused by other components. GM has a service bulletin (not free recall) about this problem.
