I know I have at least one actuator which has gone bad due to the clicking noise behind dash. I’m just not sure which actuator I need to replace. Is there a trick/tip in diagnosing which actuator has gone bad?

One other note, I think this is causing a parasitic drain on my battery. I have already replaced the relay in the SJB. When I pull fuses, #41 in the battery junction box is the culprit; however that fuse is for the SDARS and APIM.
Do you

Good afternoon,

Try changing modes and temperature. when you do those commands, the actuator should change pitch or stop until the actuator has settled.

the blend door actuator for the right side is right there. I attached the procedure for you to view.

I heard the clicking the most when changing the temperature. I already pulled the glove compartment out, so this shouldn’t be too hard to replace. Just need to get the part! Thank you for your suggestions. I’ll let you know how this progresses. Could a bad actuator cause the parasitic drain?

Blend door actuator. They are the same for both sides.

Any parts store will carry them.

Do you have pictures on how to change the LH side as well? I tested temperature on dual and definitely the right one is making a lot of noise. But, there was another noise higher in the dash on the LH side as well. Might as well change that one at the same time.
