You will most likely find your electric vacuum pump has either a blown fuse or is itself inoperable. They do fail. They are usually mounted outside in the front cavity area and typically feed a small round vacuum reservoir. Good Luck...

Welcome to the board Jerry. Find the vacuum reservoir Butch is talking about and see if you have vacuum to it. You will probably find that the vacuum hose to or from it has got a leak. Good luck
