My vent control on my dash, only works on defrost and floor mode, If i turn it to face vents i get nothing? Nothing on max a/c either.
Not sure why, any ideas?

If i turn it to all windshield vent ( defrost ) it works, and split windshield and floor vent it works,it just does not work on the face vents.

I popped off the dash cover and removed the controller assemble to check the vacuum line leading to the back and there all connected, non looked blocked or cracked, and nothing was kinked either.

Does anyone have a HVAC vacuum line diagram, so I can see what color vac line controls the face vents?

any help would be awesome! Im not looking forward to takint this issue to the dealer, I know they will rip me off for this repair!
thanks.

 

i'm in the same boat, except only vent position that doesn't work is the floor ones.
