engine knocking noise
Hi, I have this knocking noise coming from my passenger side of the car, wondering if anyone has this problem with their car? it's a 2008 g37 coupe, I know that some one in here post about the similar problem from the driver side, but mine is coming from the passenger side.

shouldve kept the camera focused at one spot instead of bouncing around. but anyways it sounds like the stepper motor/actuator trying to find default or set position. the stepper motor/actuators are part of the hvac sys. 1 of 3 things may be happening.
1. bad stepper motor/actuator.
2. lever for stepper motor may be broken as the stepper motor/actuator is trying to find its default or set position
3. one of the hvac doors or pivots is broken or stuck (least likely problem but can happen)
if you had a scan tool that can access the hvac sys of the vehicle the stepper motor may have stored a fault code and that would make it easier for u to find the one thats making the noise.
good luck
