97 crown vic/grand marquis heat and A/C question

Don't know for sure if it has one or not (Wix doesn't list one), but there a number of good products at the auto stores and dealerships that will take care of the odor. I haven't used this one

but my neighbor did and swears by it. I used one from AutoZone that was a little cheaper, but only lasted about a year.Be sure her drain isn't plugged. My mother's Honda did that, and the smell was horrendous. After clearing the drain, it took 3 treatments with the AutoZone stuff to get rid of it all. SC Tom
