Can you tell me which actuator it was and how you replaced it? My front air only blows cold.
It is call an air mix door actuator. Depending on which climate control you have the actuator is different. Mine has the automatic(the one with the 2 knobs and display) and there is the manual(has the 2 sliders).
The actuator is under the hvac cover on passenger side, almost behind the console if yours has one. Has two 5.5mm bolts holding it in. Just unplug the actuator, pull the bolts out and pull it straight down. The service manual (alldata) says to pull the console. It can be done without though. The system will require calibration with either a scan tool or you can calibrate it by leaving the battery disconnected until you have it back together. Start car and turn on the climate control, DO NOT touch any controls except for turning on the unit. It will cycle through all the settings and relearn the door positions. After about 30-45 seconds it should be learned and ready to go.
