Take the 2-minute tour ×  My 2004 PT Cruiser just flashed the
internal battery light. I was able to drive home, but I noticed
that the LED lights on the clock were flickering. I played with

I don't want to spend the bucks if I can just tighten a
connection somewhere and solve it.  share|improve this question
