Replace the "Blend Door Actuator Motor". There are three motors under the dash. The one you need to replace is the easiest of the three. It's located on the passenger side lower dash area with three 5.5mm screws and a electrical connector. To test you can actually remove the actuator motor and rotate the blend door by hand to get heat.Now that its turned cold, here is the issue. Drivers vents and center console vent blow cold air, passenger dash vents blow hot air once warmed up. Any suggestions on the fix?????
