I am looking for a contact for this vacuum pump, this pump is located
on the right fender well and supplies vac for the heat/ac. Another
question on this pump is does anybody know if it has the same vacuum
as the one located on the other wheel well for the cruise, are the
parts from the vac pumps interchangeable? The pumps are different #s
but when I have them apart, they are diff in
1 the cover on the heat one has some sort of switch mounted on the
cover, the cruise has a coil mounted in the other half.
2 the vac end is smaller than the cruise.

There used to be a 5ktd in a wrecking yard near me, I'll go and check to see
if the car's still there the next time I'm by there to see if it still had
the vac pump.
To answer your question, provided that the pumps are both vacuum pumps,
there probably is a way to retrofit one to take the place of the other - the
"coil" - or vacuum solenoid - in the cruise bleeds down the vacuum to
decelerate or releases it to shut the cruise off. From the sound of it, the
"switch" on the heater pump sounds like it is similar to the central locking
pumps, where the pump will supply either vacuum or pressure depending on the
state of the locks (ie - vac to lock, pressure to unlock). Is the central
locking pump in the 5ktd still beside the battery under the back seat, or is
this the cl pump?

Sorry it took awhile to get back but checking other things out also on
the car (found a broken hose and a disconnected one) This pump is for
the heating system only as far as I know, as the locks still work you
can hear the pump run ( I think that motor is under the pass seat). I
took the old pump apart and am sure I can retrofit a cruise one if I
can find one around here.
FYI The battery is located in the engine dept on the right front
corner(behind headlights and top is about even with bottom of lights)
Would appreciate if you checked for the other vac.
Now trying to get the low speed fan to work.
