I have 1979 450 slc. Servo unit was replaced 2 weeks ago, so finally I got ac now. Heating works fine too. Now, the problem that I have is my climate control keeps shuting off and on every minute. I can hear clicking somewhere from glove box, and than climate control either shut off or turn on. Usually it hapens when I am braking or if I accelerate. But a lot of times it hapens when I am just driving. Do you guys have any idea what this could be. Because of clicking noise I know its one of the switches. Any Idea???
Thanks a lot
