Flickering Oil Light
Time for the new puzzler. This one was inspired by a fan who wrote in with a problem in her minivan. And it just sounded like it would make a great puzzler, so here we go.
She wrote to us, years ago, and said this.
"I recently had a problem with my Chevrolet van. Anytime I stopped the van at a stop light if it was warmed up, the oil light would flicker on and off.
So I checked the oil and discovered I had plenty of oil in there. I'm becoming concerned about this happening, that I might have low oil pressure.
Oh, and by the way, I don't know if this has any bearing on the situation, but I have very little heat as well."
Okay to recap, her oil light flickers on when she comes to a traffic light, and she thinks she has low oil pressure. So, why is her oil light coming on, and what does the heat have to do with it?
Good luck.
