knocking under the dash with vent air changes
I have a vent valve knocking for a minute when possibly trying to reach its new destination when switching vent air from floor to dash to front (like the motor is not strong enough to move it so it keeps trying to reach the position required). The knocking occurs as well after the vehicle is totally off. I'm scared to take apart my dash, as it looks complicated to see what the issue is. Knocking can last for 1 min to 2 min before it stops. Any changes to the venting which provides air to the front,,,,starts it again.
I've looked underneath the driver side dash and move some cowling out of the way, but no joy in finding the item in question making the noise. Has anyone taken apart the front dash area (radio and storage)?
