I turned my defrost on for my windows and then turned my A/C on. The air kept blowing through the dashboard instead of the vents.

Welcome to 2CarPros. (and I believe welcome back)

There is an actuator on this vehicle which is operated by engine vacuum. It controls the air flow directions between the defroster and the panel. I am going to provide directions for replacing it, but before you do, make sure the vacuum supply hose is connected, not damaged, and check to see if there is vacuum to it when you change air flow direction.

Let me know if this helps or if you have other questions. Also, please confirm there is vacuum to the line. If there isn't we need to look for a problem further up the system.

I will try that as soon as possible. It is flooding where I live right now. Once that is done I will give it a try.

Hey Joe, apologies for the late reply. Everything is fine now, thank you very much. As far as the car goes, the A/C is working again. For some reason they had to change the vacuum line because something was grinding into the line and put a hole in there. They could have been lying but its working and that was my main concern.

Welcome back:

Glad it's fixed. I had a feeling it was a vacuum issue or the actuator. It was vacuum. Interestingly, a hole is odd, however, dry rot isn't. So, anything could have happened.

Regardless, please feel free to come back any time you have questions. We'll be happy to help.
