Musty Smell

New member with an odd question. Have owned a '99 Wrangler for two years - and noticed right away a slight musty/mildew odor when the a/c or heat was on. This odor is getting stronger! I have searched some threads and haven't come across this issue. Is it possible there is water in the ducting and there is mold growing? Just wondering if anyone has heard of this. Thanks - and love reading the forum! Rich

I had that happen in my ZJ. I would spray a light bleach / water mixture in the a/c intake.

Mold or mildew has undoubtedly moved into your HVAC air ducts. Turn the vent on and the fan on high, then spray the air intake with a large amount of Lysol (from an aerosol can) and then immediately shut the fan and vent off so the Lysol can stay inside and work to kill off the mold or mildew. The fan will suck the Lysol into the interior of the HVAC ducting. The air intake is underneath the cowling just in front of the windshield. Don't turn the vent and fan on for a few days. Then I would do it again after 3-4 days and perhaps one more time 3-4 days later. It takes some doing to kill all that off so one application is seldom enough to actually kill what is producing the odor.

P.S. Don't bother trying an odor masking/neutralizing product like Febreeze. You have to use something like Lysol that will actually kill the bug that is causing the odor. Bleach would work too but I hate the thought of spraying bleach anywhere.

thanks for the lysol suggestion. Regarding the air intake, is it adjacent to the front window defrost discharge?

That Lysol trick works great in any vehicle. Smells a little 'sanitary' for a few days, but it's better than that AC funk that gets in there.

Not stock.

You can add one if you want to do some fab work. But with top/doors off, is there really a point?
