From all your comments, it looks like the evaporator drain pipe is the
culprit.
Trouble is I cannot find the darned pipe, for love or money. It does not
even show up on the car manual.
Any clues anyone can share for finding the drain pipe?
Thanks, again

Hearken back to the day when the a/c condensate (water) dripped out
onto the ground,
try to remember where the wet spot wound up when you parked the car.
Above that spot is the place to look.
cheers

You might be better off looking for it in the passenger compartment.
Look for a rubber tube passing from the heater ductwork to the firewall.
It may be obvious or may be hidden behind the ductwork. In my Nissan PU,
it is just to the right of the center hump, and I can remove it from the
inside without going under the hood.

As others have said, step #1 is to find and clear the evaporator drain.
Step #2 is something called "Frigi-fresh" spray... designed to kill the nasties
growing in there,
and it actually works! Google for where to buy it, and follow the directions on
the can for use.

I remember that nasty smell in an old car I had many years ago. The
solution that worked for me was to turn off the A/C, but leave the
blower fan running in vent mode, a couple of minutes before turning off
the car. That seemed to dry out the evaporator enough so the mold
wouldn't grow while the car sat there.
I got in the habit of doing that a couple of blocks away from wherever I
was going.
