    We purchased a 2015 Tacoma, I replaced the filter in the cab/ air vent, and I’m still getting a slight musty smell when the heater is on. I don’t notice it with the a/c. Any ideas?

    I’m still on my November pair, could that be the issue?

    I have since found several cleaning kits after the link sent by Clearwater Bill, any recommendations as to the best?

    Turn it on full blast and spray Lysol in the return

    (You can’t cover up mold, you gotta kill it)

    Most cleaners seem to recommend a disinfectant after the flush. BG seems to have a one they would probably do the trick. I want to get it throughout the entire system, and be done with the moldy smell

    I believe the Lysol as mentioned would be considered a disinfectant. Blower on high and recirc on.

    I’m also guessing you have a condensate drain plugged up somewhere, hence the moisture/fungus/stank retention...

    I was wondering the same thing. Will check the drain as soon as it get back around freezing After viewing so many Youtube videos, I wonder how clean the evaporator/ heater core by spraying Lysol into the system. It would probably be disinfected, barring the wife’s smell test

    Happens a lot if the truck has been sitting. Two cars I bought had that smell. Both cases resolved themself. Try running full heat with windows open. Then Lysol, ozium has also worked well. I also have found in my case that summer is the culprit, and I try to run the a/c off for a few minutes before arriving at destination cleans out excess moisture.

    When you look in this thread and see how part of it is made, apply your disinfectant via the cowl intake with the cabin filter removed.

    Also you can attach a shop vac to the AC drain which will clear that if the tube is clogged.

    Using the thread above, you'll likely find lots of things to clean. And be able to prevent rodent intrusion (via the cowl) as well.

    Since it's new to you truck I would check the air intake and blower for any critter nesting. I found some dead baby mice in my blower one time.

    I’ve noticed this with my 12 and my brothers 13. Neither gets driven a lot, especially mine in the winter. Where is the ac drain? I’d like to check this first. I had a clogged vent drain on a 93 wrangler that caused water leaking problems for years before I stumbled across the clogged drain hose.

    I’ve always tried to turn off the ac before turning the truck off in the fall, assuming that has something to do with it but no luck yet.
