I recently noticed my left turn signal on my 7 pin trailer connector wasn't working. To make a long story short - it was a bad relay buried deep inside the integrated power module (fuse and relay box). Unfortunately, the relay was not accessable from the outside and the whole module had to be replaced - $400 for the module and another $300 for the labor!! Quite a bit of $ to replace one relay!! Anybody else run into this and what is the old module that does everything but the left turn signal on the trailer recepticle worth? Maybe someone out there needs one and doesn't pull anything!
