03 Trailblazer vent Actuator runs continuosly
I have an 03 trailblazer and have a vent actuator located above the blower assembly on the passenger side. I did not notice a airflow issue but a constant sound above the glove department. Dropped the glove box down and I can visually see the actuator moving the damper. Tried doing the system reset by pulling fuse 36. I can hear the other actuators going through the routine. This actuator never stops. I believe this is the fresh air actuator. Does not look like a fun one to replace if that is the problem??
