1992 Peterbilt 379 HVAC system actuators and switches

I got ya. It controls the vent that opsms and closes based on control position. I don't hear any leaking there so hopefully once I replace the tee I'll be working properly. WpuldnWobe surprised if it was bad though because as I work my way down the system it seems like each next part has a leak lol. Thanks guys

 

They're iny first post in this thread. They start with DA, dual actuator is da 10000 and single action is da 10050.

Those are the Pete numbers and you can find them via other sources for less money. The first dual action one I got was faulty and I had to start a warranty claim and am waiting for them to approve my refund.

Also rocketscott gave red dot part numbers for the current part numbers in some components in the system. Very helpful look at his post.
