I should have replied sooner , I took the whole dash apart , heck It's all solid state , electrical boards , way over my head . there are no ground wires anywhere . What now , it still does it . I just keep driving and it comes back on . then it will go off again . The brake light system is also involved , nothing wrong with the brakes but when I loose speedo the dash brake light warning starts blinking . I unplug the wires at the brake junction block and the light stays off until the speedo stops again . Other than probably a very expensive fix , I'll just keep driving it until I get a response from another driver that knows .
Thanks , Bob
