While the A/C is on, The Jeep randomly blows HOT air from the floor vents for 3-5 mins then stops

I would buy a Tazer for my stock Rubi if this was an option to disable it.
I'll email Zautomotive and ask him if it's something he can do.

Experiencing the same thing right now...if this is a “feature” of the system I can do without it. Smells musty and it’s warm humid air. Mostly from passenger side. Will most dealers know this fix?

There is no fix other than unplugging the damper door motor.

Or pressing the recirc button twice as soon as you feel the hot air.

This is what I did and it’s pretty simple, literally only takes a few minutes to do

My 2020 jl also blows hot air into passenger side floor with ac set to max cold. It does it every so often. I do not have auto ac. Only has 300 miles on it.

This is by FCA design ....it’s supposed to bring fresh air into the cabin area which is insane, the Jeep is not an air tight space capsule, here is south Texas it’s not needed so I pulled the plug.

I have tried unplugging the vent, but that just puts it into half open mode, never getting as cold as it could be. I've tried every way possible, even having the dealer install
"The Fix" for it. Nothing has worked, so, I just deal with it, for now. I wil try hitting the recirculation button twice, next time it happens.

Before you unplug the vent, push the start button and the vent will move. Push the recirc button and change the position of the vent to your preferred position then unplug it

This is what worked for me, I started the Jeep then set a/c to cool and pressed the recir button and the vent closed off I then just unplugged it

I reached out to Joe at Zautomotive (Tazer) to see if this is something he could write some software for the Tazer to handle this. Will let you know what he says.

Seems like a huge liability. Owners will disable this “safety feature” causing fatal crashes due to CO2 poisoning! :CWL:

Glad i found this thread - my JL loves to blow hot humid NC air into the passenger floor cabin on road trips. Is the behavior expected even when recirc isn't on? Because with recirc off our JL will do this every 15-30 minutes...
