Problem with Central Vac Hoses
QUESTION: OK i dont know if anyone here can help me about vacuum hoses, but im looking for
some ideas on my 95 Golf the air pump for my central vac locking has died once again (this
is already my second one)
now that I know there might be a problem somewhere else other than the pump
itself I need to track this problem down.
when the weather gets better and I have the time I will follow the wire
leads to see if there is a problem,
I also will look and see how the key activates the pump if the problem is at
the doors.
oh ya... each pump seems to have a 3-4 month life, so something seems to
be burning up the motor in them (and no the pump does not stay on all the
time)
Anyone have any ideas of were to look?
ANSWER: Check the system voltage ie: Battery voltage with car running
if greater than ~14 Volts your regulator could be shot.
In the driver's door below the latch mechanism there is a
rubber access plug. Pull the plug and expose the switch activation
assembly. If the switch is bad it could go resistive
and be sending current to the vacuum motor, low enough that
the motor won't run but high enough to ruin the motor windings.
