Just got caught in major rain, no power after I turned car off

i'm pretty sure like i posted that your wiper motor is what burnt you.

2 recommendations:
1. do the mad electrical bulkhead / drill mod on his website. you can probably get new/used connectors to replace your melted one... someone here might have a source for the connectors
2. rebuilt wiper motors are relatively cheap/ it could just be the connectors to the wiper motor but i'm guessing it's the motor itself has a short inside
