dual control heat on passenger side/none on drivers

Help! My heater puts out heat on the passenger side, but blows cold air on the drivers side regardless of what you set the temperature to. Any ideas on what's going on? How can I fix it? How much will it cost at a dealer to have it fixed?

Do you have the manual or digital climate control?

When you adjust temperature (driver or passenger side) the HVAC head unit provides a signal to a temperature control actuator which controls the door to allow heat from the heater/evaporative core area. It is an electrical motor. The driver's side actuator s located under the dash left of the center console. Sometimes when you adjust the temp, you can hear the actuator moving. There will be labor charges involved probably at the dealer's hourly labor rate because diagnostics and troubleshooting will be required.
