Hi

Occasionally my rear wiper seizes I don't use it often and the car is parked in open - on a Sei sporting SPI.
On the second occurrence I detected there is an O ring seal on the wiper shaft that had worn into a D ring and was allowing water to leak into shaft and corrode it.
If you remove the wiper arm and the wiper motor assembly from door and remove the four bolts from the plastic cover to the motor gear box you then can tap out the wiper arm shaft carefully) and replace the O ring, it is a standard metric ring. There should be a location clip on the shaft, you need to push off with pliers first, it can disappear into far distance, a rag covering it helps.

It would be easy to burn out the motor, or parking switches tracks.
