Yet Another AC Problem
I have a 98 C5 w/87,000 miles. When I replaced the battery recently, the AC started blowing hot air on passenger side. The air also blows mainly out of the defroster vent but keeps changing vents. It will blow cold out of the drivers vents briefly and then back to defrost over and over. I'm getting a BO446 code. I've read the threads on re-indexing the actuator gears but that refers to different codes. I cleared the code and tried disconnecting the battery to reset the actuator with no luck. Is this a vacuum problem? An actuator problem? Or both?

The code is an actuator code though and this is a common issue. I'd fix the code first cause obviously the actuator has problems and it controls where the air goes
