A/C VENT DOORS

It seems as though the a/c system is working correctly however I suspect that the doors that direct air to the vents are stuck on the heater core side instead of the a/c evap coer side. If this is possible to occur, what must I do to repair it?

Do you
have the same problem?

This one uses a cable for that. The cable may be off or broken.

Wrenchtech, thanks.I really appreciate it. I was just confused as to which one I have because on another forum a tech said it was electronically actuated via a motor. Mine has manual door locks and windows so it makes sence that it also has manual a/c controls.

That car has a problem with a temperature door. You have a problem with mode doors. Different parts.

You don't have a temp door problem. You have a mode door problem. It controls air direction, not temperature.
