Hi, I know this most likely isn't a new problem but, for me it is. I just got all the rest of my wiring in order from the previous hack job, and when I checked my turn signals, they all worked except when I turned on the left turn signal, both front lights flashed dimly and while all the rest flashed brightly when they were supposed to. SOOOOO this is isolated to the front turn signals, both flashing dimly when I set the signal to flash for a left turn. It's a 66 C20. Thanks, Josh
