sound from vents/dash area
 

hi all, (i have a 94 n/a 850 sedan) On the dash vent controls there is an air recirculation on/off switch (which i understand what it does). When the switch is on (closed) no sound, and when the switch is off (open) a rhythmic clicking occurs.:confused: guessing something is broken but not sure where to look to start. I will probably wait until the weather warms up before digging too deep. thanks in advance.

There is a lever on the motor that often breaks.

Go to 5:45 on this video. The part is located behind the glove box.

It could be the shaft the motor operates has broken and you're hearing the motor trying to turn the door to it's proper position but just clicking against the shaft.

Thanks guys, I'll look into that video, judging from the pics is seems the recirculation damper motor is it....so much to do in spring :-)

Let us know what you find and photos are always appreciated ;)
