We have the OEM DVD player in the headrests and now the driver side screen turns itself on and glitches. We can't turn it off by holding the power button. The only thing that turns it off is turning the car completely off and starting the car again. It might work or it might not, it is a sporadic issue. I am hesitate to take it to any Chevrolet dealer around me because when I do with other problems it takes them 3 days to even look at it then another week or so to "get a part" and another couple day to repair. I don't have time to leave my car there for 1.5 to 2 weeks. When I ask for a loaner they act as if I am asking for their right arm and leg. I have been to 4 dealers around my area and still haven't found one that is competent. Anyway any ideas to why the screen is acting this way? An electric short?
