I have a 2000 Saturn SL1 standard. It’s been great with very little need for repairs beyond routine maintenance. In the last two weeks it has started an odd squealing that I can’t pin point.
While driving along all of a sudden a squealing sound will emanate from what seems like the driver’s side firewall area. Acceleration or breaking does not seem to change it, nor does adjusting the speed of the hot air blower up or down.
It doesn’t sound like a wheel scraping or anything like that. The best way I can describe it is it sounds like what happens if a speed-o-meter cable needs lubricated (but of course there is none of this vehicle).
