I believe I know the three stages of radiator fan speeds -- and noise ['87
AC in my (late) '86]. BUT, yesterday, out in 90� mid-MO heat and idling (AC
on) while my spousal unit got us some Steak & Shake happy hour shakes, the
high(est) came on and, rather than being the roar I am used to, I was
treated to more of a loud howl (back in WV, we might have even called it a
squall) -- no louder than previous, but definitely a different tone; I am
fairly certain I haven't experienced THAT noise before in 10+ years of AC'ed
Vanagons. Any clues? (Searched the archive, but no help with "loud fan" or
"noisy fan".)
