I have a weird problem that's driving me nuts. The dr. turn signal "drl" doesn't come on like it should. Also the left turn signal doesn't work. The flashers & right turn signal/drl work fine. I put in a new bulb and that didn't make any difference. What else is there?

 

Bueller? Anybody? Bueller?

 

Might want to check the socket, possible bad ground in socket. Also check to make sure all the rear lights are working properly with parking lights on and also when the brake is applied, since the rear and front work together for turn signals. Just some suggestions.
