Ihave a 2004 dakota 4.7 I was driving and i felt water hit my foot then i heard a buzzing under dash them my blinkers started go crazy so i pulled truck over popped hood and shut truck off and thats it . dead no power head lights work i believe water got into my fuse box and shorted something out i have new battery new starter all fuses r good but 5 fuses dobt have power got a new ignition control swith still nothing?? Im down to fuse box itself
