2001 Peterbilt 379, a lot of the air flow is coming out the defrost. So I guess the control that changes air flow from defrost, vents, feet is shot. I didn't have a lot of time but took panel off in front of passenger seat looking for the correct actuator. I saw the blend and recirculate actuators. Can anyone tell me where the mode actuator is located?

It's on top of the Mode Selector Housing (#8 in this pic). If the actuator is working, pull it off to check out the cam (#7) and manually operate the doors to see if they're stuck or broken.
Lime Hauler Thanks this. -

About center of the dash, it's #2 on this pic. You can usually get to the mode actuator taking loose the center gauge panel and tilting it forward to get in there.
