'96 ZJ - Wipers Stop Almost half way up.

OK, I know this has been posted a few times, but the info I've seen says it's probably the relay. I have verified that the problem is NOT the relay.

Delay seems to work although it only pauses for a second or less.

Should I replace the motor and go from there?

That is for earlier model ZJs. I believe the wipers on this model are controlled by the Body Control Module. I already opened that up and it looks fine.

I noticed in the wiring diagrams that there is a circuit for "Wiper Park Switch Sense" from the Body Control Module. Anyone have any idea how I could easily test this circuit? Is it just contact closure or does the BCM send +12V or something out for this? I'm wondering if this is supposed to tell the motor to pull the wiper back down to "Park", but the circuit isn't working.

Or does this function just go bad in the motor?

I guess I can replace the motor anyway and go from there.

Hi all,

Just replaced the motor today and everything seems fine!

Does anyone know where to get just the bracket that attached to the post on the motor? That bracket is a tiny bit worn due to a loose retaining nut. I don't want to have to replace the whole assembly, unless I can get that cheap.
