windsheild wiper problem
 

I have a 2003 h2 with 87k miles . As I was driving home last nite all of the sudden the wipers just kicked on . Then they stopped then they went on intermitten , and then stoppen then came back on steadily . The only thing I have done was install a sat radio in the truck but the only install was to plug into the cig lighter plug . could the cig plug lighter have short in it ? Has anyone else had this wiper problem . I pulled the fuse for the timed being . Please help me . Thanks .
