I have a 2002 Ford Ranger with the 4.0 v6 with automatic transmission. All of a sudden my parking lights were on with the switch being in the off position. For the life of me I can’t figure out what happened. I was driving when I noticed it. I turned the light switch off and on several times but they still stayed on. Once I got home I had to disconnect the battery to shut them off. Anyone have an idea what caused this to happen?

 

Any work done recently? new radio?

 

I put a new radio in but it was at the beginning of the year
