michael and  all'
I have not  been following this thread this time, but it has persisted
so that it feels too familiar. If this has been offered, then realize
that I have not kept up like a good lister should.

 I had the dreaded blinking red light and tried everything (including
the piece of duct tape over the light), to find that the problem was
that I had too much antifreeze in the mixture.  The mix is very percise
and too much or too little will cause the light to flash.

Drive well.
