Question on HVAC ?

1743 Views 7 Replies 7 Participants Last post by  77118
Everytime I start the truck, the HVAC system defaults to recirculate..whether the A/C is on or not......then I have to push the button to turn it back to fresh. It's a PITA. :mad:
Is this normal? And if it there a way to change the default to fresh?

Mine does the same thing too. I noticed that when it is set to the coldest temp it will always default to recirc. If I move the temp up to about 67-68 it will stay on fresh.
This is the worst "feature" on the Sequoia:td:. Everytime I start the truck in warm weather I have to press the recirc to turn it off. Dealer says that it is better that way :eek: I think I will disconect the power supply to the flap that switches to cabin supplied air. Anyone know how to get rid of the auto recirc feature?
Thanks, Mike
It goes on recirculate because it will heat or cool up the air INSIDE the truck faster then it could heat/cool the outside air. This is common on many cars when you have it on high or auto from what I've seen. I don't know of any way to turn it off and really wouldn't be sure why you'd want to.
has never happened to me??? Is mine "broken"?
