2004 E150 work van

dash, high beams, lic plate and back lights blown out. Replaced fuses but they blow out when switch is turned on.Lic plate bulb was fried to socket. Any suggestions?

You are just going to have to track down the short and fix it. Frist check for exposed areas in the wiring that could be damaged. I think most shorts are found near the start and end of the wiring. If there is a harness for a trailer check that first.
