I had recently bought an 01 exp sport and realizied my left rear turn signal and brake light does not work. The weird thing is my running/dim lights all work. Ive checked the bulb and the bulb connector, everything seemd to be fine. . this is definatley not safe b/c on the road i cant let other drivers know when im turning or merging. I just dropped my truck off at the repair shop which cost me $160 for an electric diagnostic, just to find out whats goin on with it ..Such a headache !!
