Can you or anyone tell me the approximate locations of these servos? I do know that the legwell servo works ok. Also, when I removed the dash vents, I see the a/c evaporator. There is a metal rod just above it, and this moves left to right just fine. Behind the headunit, near the firwall, there is another servo just works when I hit the leg vents. Where is the 3way valve located in the car?
