The Problem has been found by my Lexus service dept.
It turned out the the Mark Levinson Amplifier was the problem and the tick was actually coming from the left front speaker.
Fuse has been pulled to stop current draw and give me some time to decide what to do as the cost of a new amp is $1070.00.
I was able to find new ones for $652.00 but still way too much money, I'm looking for a used one.
If anyone has one or a lead on one please post.
Thanks
