I have a very annoying dashboard rattle that seems to be comming from the passenger's side heater vent and rattles contantly as long as the car is running or moving. I already tried tightening screws around the glovebox and spraying some WD40 inside of the vent. Although I now have a car that stinks of WD40 everytime i turn on the AC, i still havent gotten rid of the rattle. Does anybody have any solutions to this? I was thinking of taking apart the vent but I dont know how to do it and I'm afraid to break anything. Is there an easy way of eliminating this rattle?
