just today when i turned on my a/c it wasnt coming thru my vents but through the bottom. my legs were nice and cool but i was sweating like a pig and had to open the window, it wasnt just the a/c, i had the air venting on the upper vents and it still came out the bottom. When i got in the car a bit later the air started to come out up top again. Whats wrong w/ my car??

any help? it keeps going from the bottom to top vents just kinda randomly. I need my A/C in consistently high 90s low 100 degree heat

Did anyone figure this out?
I'm having the same problem, and I'm thinking vacuum leak, but I don't know where to start looking.

In my car it is vacuum controlled. I just had to replace a hose because there was a vacuum leak on my car. Hope this helps.

After some research (search button), I was able to fix the problem.
For the folks like me who are looking for pictures on this, forget about it.
The only way you will see where the hose is disconnected is if the intake manifold is out of the way. I found it by using "The Force". Okay, in reality I just stuck my hand under the cowl and behind the intake manifold. In my case I found the fitting first, then the hose. After some hand contortions, I was able to get them together.
In short, you won't see it, you just have to feel for it.

(Note: After fixing this vacuum leak, my fuel trims were way off, so I simply reset them and all is well.)
