Today I got off from work and hopped in my truck. I started it up and headed down the road. I then realized that I didn't hear my radio so I turned it up and up until it was Macedonia out and I still heard nothing. I then rolled my window down and it started playing. I then turned on my wipers and it stopped playing again. So I rolled the window all the way up then back down and the radio started to work once again. Does anyone know what might cause this to happen? I have power Windows and the radio comes on only when I roll down the passenger window.

 

Don't use your windows or wipers.
