I've currently just started to have with problem with my 2.2 1999 Sunfire. The a/c is starting to come out of both the foot vents and the regular dash board vents no matter what I put the control to. Has anyone encountered this problem or know of someone that can help me.

Thank you

 

I had that problem on a different car and all i had to do was pull the controls console out. Then once out i turned everything to make sure it was changing. come to find out it was a tiny spring that popped off.
If thats no it, sometimes the hoses used to rout the ac and heat come loose or get crimped. you should be able to check the lowere lines behind the center console. just pull out the cupholder, (one bolt) then snapes off.
hope this was helpfull
