Hi all, for the past couple days there's been smoke coming from the drivers side vents in the dash, I tried tearing the dash up and the fuse box but I haven't found a single issue. This is worrying me. Things you should know: AC and Heat are off, they work perfectly, it's white cloudy smoke, no smell, the smoke only comes out of the left most vents on the drivers side. I uploaded two images of the two drivers side vents it's coming through

Well the vents are fed by tubes so probably not wiring/electrical smoke, it couldn't get into the tubes.

And how long does the vapor come out of the vents, and how long does the truck have to sit before vapor comes back?

You are in Calif. and the sun does heat up the dash even on cooler days.

I would check that the evaporator tray drain hose is open, not clogged up, it comes out under the passenger floor pan near the center hump, push a wire up thru it, it is just a rubber hose open at the top.
It is just water in the evaporator tray so it wouldn't have a smell, like coolant would(leaking heater core).

After truck sits a bit, do not start it or even put the keys in it, but blow thru the center or passenger side vent and see if the vapor comes out drivers side.
If it does then for sure not an electrical issue.

 

The issue was a burning headlight switch..... So I hanged out all the fuses and got a new switch

 

Good work

Thanks for the update

Usually hot wiring has a distinctive smell
