Thanks for the guide dude just went out to my 99 3.0 ranger and found a black hose near the white that had broke, put on a new adapter and plugged it back in and it's working again

What was the video about the 4.0 that you referenced in the beginning?

you need the ball thjing to keep pressure when you accelearte,,,,or you will lose the air,,,,

Your video helped me realize that my car electrician is an idiot. My car is a 2008 Daewoo Nubira and the AC redirection button uses vacuum to redirect air. The idiot was checking my AC and tried to change air direction while the car was off, so naturally the air recirculation ↩️ button didn't work along with the redirection dial. He closed the fresh air vent shut permanently using a screw so the air in the cabin always recirculate 🤦‍♂️ Sometimes KZfaq suggestions is a savior. I'll remove this screw tonight. Thanks.

Appreciate it👍

Thanks 🙏

Not a fan of the 3.0!
