Just this morning my central lock isn't responding at all. Neither the switch or my car remote would lock my car. I checked the fuse and see if everything is good, and noticed that it was busted. So I replaced it hoping to cure the problem. But with no lock, it still won't respond

Does anyone encountered this problem? Could it be the vacuum pump went bad?

 

Just an update, my central lock vacuum just died. That's the reason why my locks are no longer working. does anyone know where I can get a cheap one. Thanks.
