Water in Taillight?

Discussion in 'General Chevy & GM Tech Questions' started by backcountry horsewoman, Dec 27, 2010.

  1. 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!!

    On the dodges they are notorious for getting moisture into them, if you can finda way to keep it out let us all know.. Since with GM it is usually a seal, and some WD40 to get the moisture out. in all reality you would be better off drilling a small hole in the tailight housing (somewhere on the bottom not by the exposed part) and let the moisture drain that way. My buddy has the same problem and that is actually the best way we found to keep everything normal.
  3. Weird! I located the fuse controlling tail/dash and tested it with my ohmmeter. Got continuity.

    Now what??

  5. LOL! Roommate is a guy, but clueless about trucks. He got his 1997 Ram about 4 years ago because it "looks cool", and about the only he does regularly to it is take it to the expensive car wash for a good cleaning. Go figure that everything is breaking on it at the worst possible time.

    He's broke and needs help. So I'm helping. :)

    Sounds like its time to take a look at the grounds, and possibly the switch.. that is where i would start since Chrysler was never known for quality products/parts in some models.

    Yes, and the switch shares that fuse at the same time. If you short the circut sometimes the switch itself will fry.
