Default Clicking noise in dash?!?!

Lately I have had a clicking noise in my dash with the car running or when they key is just in the on position. When i turn the car completely off no more clicking.. Anyone know what this could be?

Could be some of the little motors that move the blend door and mode doors in the HVAC system.

Suggest you use an automotive stethoscope and try to pinpoint the location. Sounds can be very hard to locate with our normal hearing. Make sure you open up the passenger side area where the fuse box is to fully expose it. Could be a relay or breaker in there cycling. If the sound goes up when you do that you can "feel" everything in there to see if that is the cause. Something similar happened with a friend and it was a relay we found that way.

Sounds like an AC blend, temp, or mode actuator. Check for codes.

Yup, sounds like the blend/temp doors. Sometimes this is normal for system checks.
