So an update .... checked terminals on the harness ends that plug into the Rcm .They are ok ..latest system check reveals no horn,radio,windows, seats,mirrors ( almost everything in car ) What works is headlights, marker and tail lights ,.When ignition to start all dash icons light up along with spoiler light and beep but no crank then high speed fan.Fob blinks lights but doesn't open doors. This one is a head scratcher.Like everyone else I luv the car but it constantly like to test my patience. As member mentioned I may have to try and work from what I know doesn't work and trace backwards.
