Electronic feedback?

I'm getting feedback from the electronics in my truck. Like the power inverter and sometimes the windshield washer fluid pump. Never had this problem before but never had a truck where my cb was mounted in this location. I don't know if its the wires being to close to the coax or bad coax or what. My first thought was a ground issue in the antenna or coax. Any ideas where to start? I already know I need new coax and antenna just not sure if I need to change the coax routing to avoid this or if its something else. I don't want to redo the coax in the same position if thats the cause of the problem.
