Check the bulbs first, smart man!

I had a park/ turn signal problem this week with my 1994. When I turned on the park lights the left turn indicator on my dash lit up. On the flip side, the turn signal would just light up and not blink. I always read too far into things, as I am a commercial refrigeration tech. I traced wires, grounds, checked flashers, and so on. The Slingblade asked me the simplest question and I tried the simpler check, I traded bulbs and the problem went to the other side. The bulb itself was bleeding through!

sometimes the answer to a problem is so easy, no one ever thinks of it. i usually try the easiest things first but most of the problems i have had were not easy fixes.
