The windshield wipers just stopped returning to their original position. Now they stop where ever you stop them. Is this the motor?

 

There is a park switch inside the wiper motor. You'll have to replace the motor.

 

Hm, not exactly what I wanted to hear. Are they expensive? Difficult to replace?

Thanks for the information!

 

I don't know, I've never replaced my Camry's. Expensive is relative term. You could try local junk yard. I don't know if you could access the park switch and repair it, but I doubt you could find just the switch - worth a try though.

Probably not. It's accessable from under the hood.
