The Clutch is stuck which bolts on the end of the wiper motor. This can be replaced seperately
When the park circut fails the wipers will simply stop without parking at all, the clutch reverses the wiper motion and when it is stuck the wipers do park but point up instead of under the hood.
However The wiper motor is a weak link and is likley to fail soon anyways. Rebuilts tend to fail prematurely. Did my old 5.0 stang at least 4 times on my 3rd motor for the 2001.
Junkyards not a bad source for a OEM, but those fail too. So do a BRAND NEW OEM.
My 0.02 when the new part is still a weak link, get a rebuilt with a lifetime warranty, as new OEM parts have NO WARRANTY.
