Truck is in the signature

Today I drove a roughly 90 mile road trip and had the outside air flowing through the vents at the head height setting. Then I started going up and down hills and I noticed that the vents randomly changes to off and then it turns itself back on as I go up the hills. Is this the case of wild vents? If so, what's the fix to this situation?

 

Yep, that's wild vents. They actually switch to defrost..... There is a thread in the DIY section on how to deal with it.

 

That doesn't effect the AC, does it? I'm gonna be recharging the AC system soon.

 

Nope. Just where the vents blow air.

 

Ok. And I'm not really finding the DIY Wild Vents thread.

 

Yeah, I can't find it either, and my internet is being painfully slow.... Try this thread.

 

Just search "wild vents".
