hey i have a 87 n/a and every once and a while my idiot cluster lights up when i start it (the clustor of lights in the middle of the dash seatbelt, parks brake all those ones) but for the most part it doesnt ligth up im thinkin its just full of dust and crap in there cause i kinda tried cleaning out my heater vents with some compressed air (didnt do much lol) but the idiot cluster seemed to work for a little bit after .... maybe just coincidence but just looking for some help and if anyone else has had the same problem
