This morning I decided to try something in my 2012 for cellphone mounting.

It was very quiet outside and as I climbed in I noticed a tick tick tick sound coming from the right hand side of the dash. I think its behind the glove box. Wondering if it has something to do with battery issue.

Haven't noticed it before.

Anyone else got one?

Theres a number of relays on that side. They power anything from the brights to the horn. Im not sure why it would click repeatedly though.

A blend door actuator.

It almost sounds like u have a floating ground somewhere. Don't see how a relay could do that though.

It could be a blend door actuator. My old truck had and still has that problem.
