- Continue to push the mode cam onto the case and rotate left and/or right until an audible click is heard locking the mode cam in place.
- Rotate the mode cam from stop to stop (1). It should rotate completely without binding. If the mode does not rotate from stop to stop, then remove the mode came and levers and repeat steps 2-6.

NOTE:
Do not use casting marks behind the cam gear levers for aligning the cam levers to the cam gear. Doing so may result in poor HVAC performance and/or damage to the HVAC module.
