When I turn on the left turning signal the rear blinks very slowly, and the front won't light up at all. The indicators inside just stay lit. The right blinkers work perfectly, and when I use the Hazard lights, the rear lights flash, but the bulb at the front-left won't light up. I tried removing the bulb and every time I remove or replace the bulb, it works fine until I turn off the car, then it won't light up again. I also believe I stripped the screw to hold on the plastic light cover at the front from unscrewing it far to many times...
