Had the car in shop for bumper repair and they let the battery died. Replaced the battery and the outside marker lights and dash keep blinking. It looks like the power to the whole car is getting cut off and on constantly (almost like a relay is getting closed and opened every second). Fuses under passenger footwell are good. And I'm able to lock and unlock the car when the power is on for the few seconds. Need some ideas on what to check next.
