Excellent advice, Phak1
Lubricating and/or "oiling" does not always solve the problem.
And, often lubricant was was put in the wrong hole/holes.
Taking the vacuum wiper apart and cleaning out dried lubricant does not always solve the problem,
Sometimes seals are bad.
Unfortunately, rebuild kits are not available.
Wiperman sends back to you an almost good-as-new wiper motor.
