Hvac codes
I have a 97 c5 with climate control. I cleared this codes on the DIC bo361h, bo363h, bo366h, bo367h, bo446h, and they come right back. When I start the car in cold weather both sides will get hot, if I then cut the car off and start it right back up the left side will blow cold air and the right side will say hot, what do I do next?

B0361 - Left (HVAC) actuator feedback short to ground
B0363 - Left actuator feedback open
B0366 - Right actuator feedback short to ground
B0367 - Right actuator feedback open
B0446 - Right actuator out of range
Sounds like you need new actuators. VERY common problem with these cars if you have dual climate control. Sometimes you can just "reindex" them by pulling up HVAC on the DIC and holding the reset button until you hear the actuators resetting, but if that doesn't work you may need new ones. The driver's side is fairly easy to get to if you are limber, the passenger side is a bit more complicated.
