UGH!! Yeah, that's what I feared. I did find the original water leak in the improperly installed gasket under the spoiler panel and corrected it and NEVER saw a drop of water again... BUT. I'll have to pull that side apart again and go look. I didn't replace the brain (though I do have a complete 2nd unit just in case), but only a multi pin connector that corroded off the brain. Cleaned all terminals and rewired with solder and shrink tubing... BUT... Sigh... back into the trunk I go! Thanks for your answer as it "confirmed" what I suspected. The alarm issue is weird though.
