Another C5 AC issue
Guys had the normal 98 C5 with hot one side cold next side all codes came back to drivers actuator. Ac was checked and full prev owner gave me an extra controller also so it was an ongoing issue. Load story short pulled the top dash and replaced both actuators cleared codes and did the fuse thing. Both actuators self test fine. Can start the car and get ice cold ac from both sides. Now dash top still out. I can turn temp up from 60 to 70 anything. And doors part close. When I go back to set back to 60 they both stay in the same position part open and I get all my codes back. Can’t be sure either controller is good to be honest. I feel if I had an actuator or door issue it would code on self test. Any thoughts or suggestions welcome.

Both controllers ended up being good only one was dimming I corrected that. I had to re index both actuators as I had read everywhere and everything started working fine. Oh except at that point my blower quit working.
