I had the same problem with my coupe, one hose had fallen of the connector of the pump.

The passengerdoor and trunk would not close or open. Also the pump will go on for a few more seconds and then shuts off and make a strange sound.
I probably loosend the hose when i was trying to get a bit more length on the cdplayer wire.
My fix was just reconnecting to hose with the pump.

Good luck with the fix, hope its as easy as mine was.
