AC is only coming out of the defrost vents. Doesn't want to switch to center AC vents. Maybe vent door motor??? Where is it located?

 

Hi Jim,
You will probably need to remove the glove box to see the duct work and controls,
If you watch carefully, you should see the different doors operate when different selections are tried. Look for one that doesn't respond at any selection and that should help to locate the malfunctioning door control.
