Okay, here's what I found. Finally it replicated the clicks and I used the stethoscope to hunt down the source. I tried the ECM unit and anything thing else in the area, even went under the hood around the firewall. Finally I put the extension on the scope and reached under the dash area all the way to the back of the fuse panel and bingo. I removed the panel cover and the clicking was coming from RELAY 1 whose description in my owners manual shows to the ELECTRONIC FLASH RELAY. I pulled the relay and the clicking stopped. NOW... what does the relay control?... not my flashers because they work with it out. Anyroads, I purchased a new on and installed it and so far no more problem and hopefully the next few days will bear that out... we'll see.
