Thread: Constant clicking noise in cabin.

I continuously hear this constant clicking noise inside my car. Its very faint. If I had to describe it I would Say it sounds like the blend door actuator constantly switching around. It does it with all the air turned off, maybe with it turned on too but it's so quiet with it on you wouldn't be able to hear it? So is this a blower resister thing? The actuator itself? Or maybe a vacuum leak? I should also tell you that all my hvac controls seem to work fine. Thanks for the help.

So if it is the actuator making the noise. Is the actuator broken or could it be other things making it switch back and forth?

In the first yr or so of owning my 97, i had a similar thing. turned out to be my speedometer cable was loose.
