I go through the drain tube underneath the truck. I use AC evaporator/coil cleaner. Let it sit 20 minutes then start it up and run the AC on high in recirculate mode. Cabin filter out of course. No musty smell and I live in the humid SE corner of VA.

My '18 rebel, I have NOT done a great job of changing the air filter (I think my current K&N is the 3rd filter the truck has had in the almost 6 years I've had it, coming up on 84k, and the wife hasn't complained about it being musty, other than when the truck has been parked for a bit...

I basically set the AC when I first bought it, and other than adjusting the setpoint a couple degrees, I pretty much have just left it on "AUTO", except when someone riding in the passenger seat complains, or ****** me off by adjusting the AC.

Gotta teach the wife that changing the temp when the AC is trying to beat the heat down does NOT change anything. (IE she'll set it to "LO" when she first gets in, but turns the fan speed down, as she doesn't want it blowing mach jesus air on her. At least this is what she does in her car. I've basically told her not to do that in the ram, but she constantly fiddles with everything. Blower angle, turning the vents on and off, ******** about the fan speed, but she almost never changes the one thing she NEEDS to. The temperature.)

Cracking the windows a little bit with fastest blower speed works very well. Once the "infra red" heat has been removed from the cabin (about 1-2 minutes), then turn the blower down to the next lower speed. The slower the air is passed over the surface of the evaporator core, the more time the temperature can be absorbed from the warm air to the colder surface of the evap.

Funny how the "Auto" setting on my wife's Sorento does this for you.... except rolling the windows up after it gets cooler inside!

What cleaner did you use?

What cleaner did you use?

Frost King foam coil cleaner. About ten dollars for a 19 ounce can on Amazon. I use about 2/3 of the can on the truck and the other 1/3 on one of the kids econoboxes. I’ve also used Lubeguard Kool-it evaporator foam cleaner as it comes with a really long tube that you’ll want to save for future use with other brands. The nozzle tube is about 18 inches long and it really works better than the regular short supply tubes. About the same price but the can is much smaller.

Id run a ozone with the battery hooked up to a trickle. Run it on the recycling cycle for a few hours. That will kill the smell. Trust me if if can kill raw pork that was sitting in a brand new suv for 3-4 days with temps over 100* it will kill it.

I will have to look into that. The only foaming coil cleaners I've seen and used are usually the ones that are very harsh and I really hate to use them because you never really get all the residue out and it just eats the crap out of the fins over time, even if you dilute it down before use
