My 1983 300D's famously beloved automatic climate control system fan develops a high pitched squeal after use for 20 or so minutes, squeal is constant, low volume, climate control system works well otherwise. Is this a symptom of fan brushed or bearings? If bearings, can the fan be lubricated as opposed to replaced, and if so, where are the lubrication locations? Thanks.
