I just got my 2006 4.4i e53 back from dealer for service.

Part of the service, I believe, required the dealer to remove wiper wash repository.

When I tried to wash my front windshield, the rear washer releases fluid and when washing rear, the front releases fluid. So, the dealer reversed a connection. I would like to fix it myself without having to leave vehicle at dealer.

any ideas on how to correct this?
