Hard to say unless it does it alot or stays bad. Bad ground or connection jump to mind first.
Hmm if it's a bad ground that would suck; I just replaced the battery 3 weeks ago and the starter 2 weeks ago.
There are more than 1 ground. The dash wiring harness soemtimes has its own ground, let alone if a connector in the dash is loose somewhere.
If it does not happen again then don;t worry. If it does see what harness and ground both the radio and wiper controls go through.
Dumb question: If the two go through the same ground, how would I find that ground and re-ground it?
What kind of car is this?

That is where you need to begin.Did you loosen a ground around the battery when you replaced it?etc.Hmm if it's a bad ground that would suck; I just replaced the battery 3 weeks ago and the starter 2 weeks ago.
