short story; mines works again... i took out that duplexer, wire brushed the crust off, tooth brushed the holes with nail polish remover, clean it some more, covered the contacts with dielectric grease then reinstalled. worked like a charm... now the whole story; i've had scattered rain storms this whole month when the "sos tele aid" popped up... i waited 2 weeks to see if it would go away but didn't... i noticed the truck was damp and taking in water.. water was pooling in the spare tire well, not a lot but enough.. i took out everything damp, tire cover, tire, carpet trim... i even saw a little mold.... *i was able to remove the side panel by itself*...wiped everything down and blow dried some areas... then left the trunk open to fully dry out(2 days in the cold garage) before i touched the duplexer.... anywho,, good luck!
