Well, it's flashing now and I don't know why.

Changed bulbs, unplugged and plugged the connectors, cleaned every connection I could get to and worked the lever up and down a lot of times. Nothing helped. I gave up, got in it to move out of the way until I had a chance to review what you all had to say and the darned thing started flashing.

I guess I am happy, but I sure would like to know what the issue was.

Thanks for the help guys. If it quits again, I'll be back.
