I have a slight issue with my above 500 POP. (2008) When the DRL's are on the drivers side bulb does not work. This is confirmed with a warning signal on the instrument panel. However, if I put main beam switch on then both left and right DLR bulbs ignite. I have had the car for 12 months and still learning. I should be very grateful to receive any help or quidance on the issue. Many thanks.
