Hey everybody, this is a great website. I was hoping you could help me with a problem I am having. I have a 91 police interceptor that all of a sudden lost its floor and defroster settings. I figured that it was just the little vacuum thing under the dash but when I crawled underneath the dash and watched it work, I realized that couldn't be it. I disconnected the arm from the motor and swung it manually but I still didn't get air out of the floor or defrost. It doesn't feel broken. Any suggestions, also what do I do next?
