I have a kenword touch screen radio in my 2002 Civic. Everynow and then, when I activate my left turn signal, the touch screen will begin to flash (not really flash, just brightness changes) , the turn signal will stop working, and the flashing of the radio stops. For about 30 minutes, that turn signal indicator will not work (the actual light still works, just not the dashboard indicator). After awhile, the radio will do the weird flashing thing again, and then the signal will work again! Whats up?
