Honda CR-V 2007 120000 km
I disconnect the negative cable on the battery because it can drain overnight. When I screw it back on, everything seems fine. Few minutes of driving later, the dashboard turns off. The speedo and tachometer gets stuck in place. The LED display turns off. Car still runs fine. Windows still roll down, turn signals work, radio fine. This wouldn't be a problem but the A/C doesnt blow cold air. Fans still work but just nothing cold. Few more minutes of driving again and the dash comes back to life again. Is this a grounding issue? How do i fix this
