clicking sound coming from dash

[redman]

I have an 06 titan LE, and over the last month or so everytime I start or shut off the truck I get this strange "clicking" sound coming from my dash. Sounds like its either behind the instrument cluster or the stereo not sure. It clicks anywhere from 10 seconds to a full minute or two. Its a very fast clicking and very loud. Sounds too loud to be a relay. Any thoughts as to what it is?

Mine does that. I was told it was the aculator for the ac maybe something like that. lol I'm a determined woman who is learning to repair my Titan since it's breaking me money wise. Lol

Whenever you shut the truck off, the heater/defroster doors reset so as to prevent a vacuum in the truck. When you start it up, they go back to wherever they're supposed to be based on your settings. I would guess this is what you're hearing. My truck does it. So does my other car (a newer Kia). The delay on the Kia is a little longer so you wouldn't notice it unless you sat in the car for a minute or so, whereas with the truck it starts faster.

Same here... no problem.
