Thank you for your response. It is definitely coming from inside. I partially removed the interior trim and the noise appears to be coming from some kind of "electrical box" about 6" x 6", but there is a metal frame that I could not unbolt without taking the "whole car" apart (at least to a layman like me the rear fold down seat look like it may have to be removed to gain complete access). Update, the ticking sound still starts at ignition but now continues for only a few minutes and stops, until the next time I start up the vehicle.
One problem I can foresee is that again to layman it appears to will require much labor time just to remove the trim, metal frame, seat(?), Etc. At $XX per hour.
