no defrost

Heater only blows out of dash vents. Is the switcher vacuum controlled or electronic?

Should be electrically actuated.

All the actuators are electronic. Go under dash drivers side and look under there you will see white arms with a motor
Attached to them. Tune the mode door dial and see of the motor try's to move at all. If so the comp is seeing the command. Most times the actuators go bad and don't move or move very little.
