'89 SC wiper motor

Any hints or suggestions to changing it?
looks like alot of work.If I go used will
other years interchange?

I would think they are interchangeable.

Well hell.. This is all I could find for you...

It's a diagram for a 1990.

Book Calls for an hour out of warranty, and 0.7 hours For warranty.

I was going to post a diagram of the wiper motor cowl, but they 80K file size limit ain't gonna cut it.

If you want it, PM me and I'll email it to ya.

Should be interchangeable I wouldn't think they would use different ones.
