Another blower issue..

[Zcubed]

so are you saying with the vents in the forward position only
that they don't blow air out at you at all even on full  

remove the glove box and you will see the motor and arms on the Hvac to the right hind side
operate the controls on the blower and see what arms and cogs moves and what does not move

Hi,
No it's more complicated than that. Each time you press one (or more) of the manual air direction buttons, you can hear something moving (presumably the air direction motor?) and when it stops the blower blows air out of the vents but not necessarily the one(s) you've selected. For example, you select feet only, but the blower blows air out of say middle and feet. You then select screen but now it blows out of the middle and screen. It never seems to be what you have asked for and is not always the same!
Hope that makes some sense!
Thanks for your help
