Could be the switch, I had an issue like that with a switch

besides not filling the bladders my passenger seat pump was doing something similar, started out strong but would slow way down as it ran, not stopping completely though.

Anyway, when I took it apart I found that the rubber torn in several places and it was winding up around the motor shaft(?), where the screw holds the rubber to the drive. It's like a crank type of set up and one of the fragments was winding around the drive & stopping the motor.

The rubber dish washing trick over at the Reg site did the trick!

Or got to a Local bicycle shop and get an old inner tube, that is what I used

As stated already could be the membrane jamming up things or it also could be a bad electric pump motor...after running a bit 'bearings' start to lock up or armature overheats.

In my case it was the membrane bunging things up (Membrane detached from Plunger) >>>

All the pieces from the membrane>>

Once you get apart here are your basic components>>>>

If it is a membrane issue then you can repair>>

If it is the motor unit... well then you will be getting a replacement pump which runs about $150 new (the OEM manufacturer no longer makes the lumbar pumps)

Thanks,
I got my project for this weekend.
