When i turn the 'fan' on to the first level, i hear an annoying noise like they forgot to lube the fan or something. with the radio on, you can barely hear it, but it annoys the shiit out of me, i want to rip my dash apart and fix it. This same noise started on my ex-****'s 93 Cougar and got worse to the point of total annoyance. I dont want that to happen. Anyone know WTF this is? or how do fix it?
