White smoke in Cabin

New to the forum -
I have a 2021 Tundra Limited -
Today it is about 75 and fairly low humidity - i had the AC on heading to a lunch meeting - An hour and a half later when i returned to my truck, there was a white "cloud" in my cabin. No smell really - looked like a vapor... When i started the truck a little more came out of the vents - i rolled down the windows to let it all escape - and never did it again on a 5 mile ride back to the office. My AC was recharged yesterday.... and the AC is still blowing very cold. I read another post on a forum that folks were assuiming this was a humidity issue... I dont think so...
Any thoughts or insight?
thx

Could be just residual Freon from the recharge? Also, did your system require the recharge so soon (3-years)?

 

The timing seems too coincidental with your AC just having been recharged.

I wonder if the system has a pressure relief blowoff valve and it released some refrigerant?

Seems awfully soon to need the recharge, has it been leak tested?

 

Ive seen that happen on different vehicles when AC was super cold and level of humidity was right.

I would not be concerned unless it became regular everyday thing.

 

Our 5.7's are pretty dang powerful... If you were on the gas maybe it could've been a vapor cone?

 

Yes - needed a re-charge was low - So has to be a leak somewhere i would assume.
They evac'd the lines and then recharged with freon and It held steady pressure for 30 minutes after they gassed it back up. They placed a dye in the system and told me to bring it back in 2 weeks and they would black-light for a leak. I called today them and taking it in tomorrow for an inspection. They said may be evaporator coil... which is bad news if it is. Looks like it is behind the dash.

 

Probably a leak. Might need a bottle or two.
