Vehicle: '07 Saturn Vue, V6 3.0 l engine, automatic, 60k miles. Problem: Several weeks (onset of colder weather for So. Cal) ago, my daughter noticed a clicking sound coming from the top of the dash when she turned the knob to the defrost setting or changed the panel/floor vent settings. There also was a similar sound when the temp selection knob was turned. I verified the sound, it sounded like something trying to engage. gears/slot?.I think it must be an electric motor driven system vs. a vacuum system, because the engine was not on when I did the experimenting. It's not the moving a lever type that controls cables that move the directional blend doors. Questions: 1. Am I right that it is a small motor driven system that works some kind of gear lever system? 2. How easy is it to get to it? It seems the click sound is right under the center of the dash, right above the control panel and radio. There appears to be a separate piece apart from the rest of the dash. I'm afraid to start prying without knowing where to pry and ending up breaking some plastic part Anybody knows or has heard about problems in this area for the Saturn Vue's?
