2002 chevy trailblazer_lt
all of a sudden the signal arrows in my dash for the right started blinking fast, when i went to the rear and checked my tail light signal i noticed that it was blinking but really dim. i opened up the tailight and noticed that there was a clear grease where the signal bulb goes is that supposed to be there? if it is then what could be the problem. the head light signal works just fine.
