No start no dash lights

Does it crank or anything ? Or is there no response from anything when key is turned on?

 

Have you checked the obvious things like the battery cables and connections?

 

Check fuse box for blown fuses... if you turned it on and started the truck and was running fine until u turned on the wipers.. It sound like wiper motor shorted out into something and blew power somewhere that took out everything else... what is model and year of truck?

 

Do u have a Volt meter ? Take voltage reading at batteries and at starter.

 

you are going to need to test your voltage to see where your power is going.
