Audible Clicking - Rear Defrost

[DecOFlaherty]

Today, I started hearing an audible clicking. It sounds a little like a turn single but more like a relay.
It sounds like it's coming from the left side of the instrument cluster, but I can't be sure.

I was trying to figure it out when it was happening and it seems like when you hit the break and when it switches gears, but I can't be certain.

A did a little testing in my driveway and it seems like the rear defrost is turning on and off with each "click" regardless of what I do with the button.

Any ideas? I recently had a switch replaced behind the cluster because the cluster lights and rear lights stopped working.

Thanks.

Ok. I'll reply to my own post.

Some trips it never happens and sometimes it's constant. The rear defrost keeps clicking on and off.

My only course of action is to replace the button (I understand there's a timer behind it) but when I look around, They all I look rectangular and mine is round (2002 V6 4L)
