I have been helping clueless roommate with his troubled dodge ram 2500's cooling system lately. But, before I can even fix that problem (am doing a radiator R/I when part arrives), he came home last night upset with a new problem. When he got off work and started truck, he had no working tail/dash lights. He said he saw water in his taillight which caused his rear light and his dash lights to go out (am thinking it blew the fuse, as I had a similar tail/dash lights issue when my running lights wiring was grounding out on my horse trailer). I am assuming it does not matter that it is a dodge vs. chevy, as it could apply to either type of truck. I am hoping this is a common and simple problem, and that the fix is as easy as replacing a gasket or using a type of glue to seal the taillight so no more water can fry out the fuse?? Any tips? Thanks!!
