Hi everyone!

Heres my first question:
My 02 Grand Marquis LSE (170K miles) has starting making a clicking noise from under the left side of the dash. It sounds just like the turn signal clicking. It is not a steady noise nor is it repetitive. It almost sounds like a pattern of different numbers: 3 clicks, 9 clicks, 1, 3, 8....completely random as far as I can tell.
I've had the battery and alt checked, twice. All ok.

Couple odd things:
1) it comes and goes. May drive 2-3 days and not hear anything. Next time it is click click click
2) Touch the brake pedal or use turn signals it quits until which ever is turned off.

Help please!

Thanks
Bryant
