[V8] Climate Control revitalization: Thank You

[Campozano, Robert]

To Ed, Tony, and Dave a *BIG* thank you.

I have enough information to do the job.  I will be wrenching tonight so
if everyone can collectively cross their fingers and say a couple Hail
Mary's for me I will let you know how the work comes out...man...I make
it sound like I'm changing the timing belt or something...oh well, maybe
one day I'll be able to do that to.  Thanks again.  This is a truly
great list...Zay

I read thru all the intervening emails and would like to see if I can
clarify things for you, assuming you need that.

The blower that blows air through the dash, etc. vents into the cabin is
under the cowling at the base of the windshield.  I think you've got
that all sorted.

The aspirator is a tiny little thing under the dash that sucks air in
from that little vent in the middle of the dash.  It is not directly
under that vent though and as others said, you can't lubricate the
aspirator by spraying anything in that vent.  The dash top (crash pad or
whatever someone else called it) has to come off, which is not terrible,
but not fun to do either.  

The clunk and squeak from the engine compartment is most likely the a/c
compressor engaging.  Mine does that only when the car has sat for a
while.  

If you have no air blowing through the vents into the car, then you have
an issue with the blower under the cowling cover at the base of the
windshield.  If you have airflow, but it's not cold, you might have an
issue with your a/c compressor or clutch.  The worst that the aspirator
can do is annoy the hell out of you and ultimately not draw air to
sample for the automatic climate control, which I would guess would
cause the CC to think it was way hotter than it is and it would run full
blast all the time.

If you go after the blower, you do all that stuff to gain access to it
and then the hose you need to remove is pretty plainly visible more to
the driver's side of that area.  I've been periodically treating both my
V8 and my '89 200 to a WD40 bath for over 4 years and they still seem to
be pretty happy.  Sometimes I use electrical contact cleaner in addition
to WD40, but they seem to be happiest if WD40 is the last treatment they
receive.  The smell doesn't linger long enough to be an issue.
