I've tried all I know, which is not a lot, and I can't solve it - please help. When I apply the left turn signal on my "93 Ranger , it works - bulbs flash on dash, front and rear...a little bit slower than the right side operates, blink rate increases with increasing RPM's. When turned off, the dash light stays on, full brightness. The left dash light will flash on/off with the hazards also, but when shut off, left dash light is on again. Please help me hunt this down, I'm really annoyed at old girl right now...thanks.
