fan switches from recirc air to outside air automatically.

I have a 2013 Tacoma dbl cab. When it's cold in the mornings, I turn on the heater and fan and use it on recirc air to keep the heat in the cab. After (exactly!) three minutes, it automatically switches to outside/COLD air. It seems to be set on some sort of timer.
I would love to disable this timer if possible so I can manually switch from outside to inside air.

thanks

 

instructions are in the manual. mine is a 2013 and I deactivated it

 

I had this problem a while ago and i was very confused. It will do that automatically when the outside temp is below 50 if i remember correctly.

To turn it off, hold the recirc button for 3 seconds.

 

Thanks!! I will definitely try that tomorrow morning!!

 

Yeah it does switch to outside air automatically, I can't remember why. You can disable it, but it's only per key cycle IIRC. There's info on it in your owners manual on the specifics though.

 

Thank you so much!!

 

per key cycle?

mine fixed permanently. .

 

Well there's always 20% outside air entering the cab(by law, to introduce oxygen into the cab).

So you put it on recirc. And after 180 seconds, the light on the button goes out?
