I recently got a 99 v70 awd. a few days after getting it I noticed that the back light for the gauges was acting up, but it quickly went away and I thought nothing of it. Then last night when I went to take it on a quick errand the problem returned, and it wasn't just the gauge lights that weren't working, none of the head or tail lights would work either. I'm guessing that this was true of the first time, but it was during the day so I didn't notice. This morning I went out to look at it and it was perfectly normal, then this afternoon when I went to take it out, the lights stopped working again, turn signals included. I brought it back and put it in the garage so I could look at it and everything started working again. Any suggestions?
