Heater help

Ok so here is my question. My heater only blows air from the center vents and won't switch to any other vents. I was just curious what might cause this. Other than that the heat and ac work fine. Thanks for all your help.

you lost you vacuum supply to your environmental controls. Check for open vac line under the hood, or pull the HVAC panel out of hte dash and check to make sure the vac manifold hasnt popped off the back of it. That happened on my DD once.

There is usually a line that runs into the car around by the master cylinder. I snapped mine the last time I pulled the motor out and my hvac controls wont work because of it.
