I assume that the rest of the wiper actions are normal and your only concern is they park themselves with a "THUNK!!!
. My 89 Le Sabre did this and my '91 Royale does it too so I think
what your describing is normal. The blades are hitting the runbber stops at the base of the windsheild. BTW, the former engineers at Oldsmobile designed in a bolt at the base of the metal plate below the windsheild that was in the direct path of my left wiper when it parked. Needless to say it cut the middle of the rubber blade so I had an arc on the windsheild that would never get wiped. Suffice to say I removed that bolt before I replaced that blade.
