Thanks for your response, Ian.
I wonder whether -- as one other feeble, last-ditch, lazy man's attempt --
one of those commercially available chemical cleaners might do any good? Or
are they only intended to reduce odor?
I'm not sure what you are referring to. There are
deodorizers available, but of course that won't help
a plugged evap core. As far as a chemical....it's hard
to see how one would apply it. "If" the evap core is
actually plugged, it usually takes something fairly strong
like engine shampoo to clean it up. Plus, it helps to
be able to actually direct some water at the fins.
I doubt that just running some chemical in thru the
air intake would do anything.
Unfortunately, the design of the W-bodies makes
it almost impossible to access the evap core fins
from the engine compartment. Too bad, really....as
this is a simple job on many other car lines.
Have you checked your owners manual to see
if you may have a cabin air filter in that year?
I can't remember off the top of my head when
they started putting those in the vehicles, but
if you had one, I've seen them get quite plugged
Well, I suppose that you "might" be able to see the evap core from that
filter housing....or possibly you could get creative and snake a hose down
in there and see if you could wash the core off sight unseen.
Sorry we can't be more helpful.
Actually, I was only kidding, but thanks -- that's good to know.
That tells me that it may be next to impossible to snake any kind of vacuum
hose down in there and past the blower in the hopes of sucking debris off
the evap core.
On that same 99 Intrigue, I just noticed a curved, sliding door that can
pull forward to cover the fan. It rests just below the cabin air filter,
and it has an indentation as though intended as a finger-hold. It seems not
to actuate with the system set on Recirc.
Anyone know what it is for?
