Beemon Posted June 21, 2015 Share Posted June 21, 2015 I'm trying to solve the reason why I lose 8 inches of vacuum after I've hooked up the new vacuum lines. Disconnecting the lines at the first T and hooking up a vacuum gauge I get a solid 18 inches at idle. I pulled the wiper motor and it had crusted overt so I cleaned it up with brake cleaner, made new gaskets, added new grease, reassembled and hooked it back up and am still having vacuum problems. The motor turns when not seated at 12-15 inches of vacuum. The only other thing I can think of is that either the fluid pump itself has a leak, or I wired the motor power line to the switch power line. Could either of these cause this big of an issue? I think I've ruled out the motor because I sealed the gaskets pretty well. Link to comment Share on other sites More sharing options...
