You have reason, the pump is down the rear seat and it is the only device that supply vacuum to the doors. My pump is burned, and the mini compresor is stucked or blocked.
The Blacksmith didn't know how to oparate the vacuum system lock and did'nt take care about leaks and the continue time operating the pump.
At least he fixed the mechanical part of the lock, and now we can lock the doors only with the key without vaccum.
I have ordered the vacuum pump.
