The '99 Intrigue has a moldy smell since we've started to use the A/C
more now that it's warmer. I would guess that this is due to bacteria
on the evaporator, or a plugged drain line. How accessable is the
evaporator and/or the drain line? Where are these located?
The drain line is usually a small elbow that protrudes through the
Accessing the evaporator usually requires substantial disassembly
under the dash. Every car is a little different and I don't know
about the Intrigue.
If heard that a solution to this smell is to allow the blower motor to
blow for about 10 minutes after the car (A/C) is shut down. This
dries out the evaporator area and prevents the growth of bacteria and
mold. It is possible that GM can program the car to do this or that a
device can be added on to keep the blower going for a while after

I recall reading a while ago that Ford dealers (iirc) offered a procedure
that would kill the mold on an evaporator without disassembly. Closed the
flaps and flooded the airbox with an anti-fungal solution, then vacuumed it
out. Someone later suggested that shops specializing in automotive A/C had
it available as well.
Don't know anything else about it, like whether it was specific to Ford
designs, but might be worth a call to a dealer.
