Stinky HVAC (fix)

[CarGuy]

I have yet to try this, but is interesting. After it's working for a few hours, you can always remote start the vehicle for 15 minutes and have the HVAC run it through the system.

That's the same chemical as the one I recommended. Just a different brand. It should work great. Sunlight will break down chlorine dioxide.

In the past I just tossed an ozone generator in the vehicle for a bit. Kills all smells....and insects

As OP stated, that’s how he did it and appears to work. However, most of these have instructions to drill hole in box between fan and evaporator, turn AC on Max and insert tube with provided tip and empty contents into plenum. Then plug hole with provided plug. Here in Arizona I do it to all my vehicles about 2x a year. Here’s a picture of my chosen location on Bronco with plug. There are many different brands with different instructions and parts, so not all the same. The one Ive been using for a few years now has tube, tips that fit into drilled hole and the plugs to seal it up when done. As was mentioned here in this thread, the filter does get a musty smell as well so not a bad idea to replace it also. On a side note, OEM filter I’ve found to be best, some of the other cabin filters claim to filter more microscopic elements but have found that air flow gets really constricted with those so I’ve gone back to OEM.

Not sure what I'm looking at here? Is this behind the glove box?

Under glove box passenger floor area next to Transmission hump. HVAC air channel between fan and evap.

Not sure if engine type matters (mine is 2.7), but it’s right above the exhaust pipe coming off the engine, where the evap coil itself is located. Mine does the “sizzler” after a long drive when hot and drips rights onto the pipe. I saw it recently when doing the oil change, it’s a decent side drip tube. I would think unless if you got mud in it, it would’ve be clogged up so quickly, but could be wrong (and not sure where you live).

Don’t forget the cabin filter too on the passenger side. Mine was far dirtier than I was expecting when I I changed it for the first time a few months ago. Very easy to do.

As a side note to the mods we all do - “drift” on Amazon in teak oil scent, are awesome in these cars!

Can you possibly give a zoomed out and zoomed in photo of where exactly you see the drain? I have been looking with a light both under the car and in the engine bay against the firewall and surely I’m staring right at it…

I too have been scouring the 'net, looking for the drain outlet location.
