Matt, replacing the aspirator is a real PITA! It runs when ever the heater
controls are on. Mine started going bad by an occasional squeal on cold
mornings which dulled to a rattling noise after the car warmed up. Finally it
turned into a full time squeal that was louder than the radio turned up. I
bought the part at SJM for around $50, (you will need to remove the connector
from the old motor, remove the one from the new motor and solder the wires so
the stock harness plug will work. Follow the instructions in the Bentley (not
real clear) and some help from the SJM site, I think the SJM pictures are off
a 5000 and the 200 is different.
The fan sucks air through the small vent on top the dash over a sensor that
controls the climate control interior settings. You can test that air is
moving through the opening by placing a very thin tissue on the vent to see if
it sticks (fan running).
The quick version on replacing is as follows:
Remove instrument cluster, glove box and wood dash trim. Remove right side
dash speaker (I have an Avant).
Remove the hose from the right side dash vent hose, the screw is deep under
the speaker (good to used magnetic screw driver).
There is a metal plate that holds the aspirator, the cruise control brain
box etc, mounted vertically behind the metal recessed area above the glove box
(behind where the wood trim was). You will see the 4 small hex screws in that
recessed opening, remove them to free the plate.
I laid inverted on the passenger seat (if I did it again I would remove the
seat for easier access), push the air hose from the vent out of the way,
blindly remove the connectors to everything on the metal plate, slide the hose (4
of 5 inches long) off the nipple on the aspirator motor that goes to the
sensor/dash vent off.
Remove the plat from behind the dash and the old aspirator motor, do the
plug/solder connection and put everything back together.
If you IC need work, may as well do it at the same time. You do not need to
remove the dash cover.
If you need more explicit directions drop me another E-mail. I think I
Plan on spending the better part of a day on this job.
While I was in there I fixed my AC recirclelation flap and cleaned a thick
layer of crud off the AC condensor (it had a thick mat of crud and leaves on
it), got much better air flow after words.
