I was in the middle of doing that when I noticed this issue. I now need to know if this is an issue with the wire or if the motor it had when I got it was wrong all along. If this is the problem, I will have a stroke.

Your issue of the wipers trying to start was exactly my problem and I cleaned all connection but the switch cleaning/plug (at the switch) cleaning made it work perfect again.
Including press once to wipe and spray.
Good Luck

My 85 has 3x wires on each connector, there are 3 wires and three connections to the connector that connects to the motor.
I know the 88-96 is a different part to 84-87, if you have 3 wires looks like you will need to replace the wiring harness plug.
The link to a 88-96 wiper motor below it shows 3x terminals.

After looking things over again, I've come to the following conclusions:
1: The cable at the bottom of the motor is normal, apparently. All it handles is the actual motor's rotation, and that has no issue.
2: The issue is definitely related to the connection between the switch and the motor. I'll check the contacts again, but I'm reasonably certain they're fine.
Related to #2, the shaft connected to the bracket that moves the linkage is supposed in a specific manner due to a mechanism on the motor connected to the wiper switch. I'm pretty sure something here is the issue, but I can't determine. The contacts inside the motor are touching the control chip, so that isn't it. Apparently Camaros and Trans Ams from that generation at least use the same motor and general chip setup, so I'm now looking into problems with those cars identical to mine in the hopes I'll find a fix.

Dang. I put in TWO new motors. Each ran, SLOW, and then slower, and pushed the fuse HOT until it BLEW -- 25 AMPS.
Old motor runs FINE, but wont completely turn off.
I am about to send the motor to Chicago Corvette and have them rebuild it. I think the circuit that monitors to motor position and the OFF position is bad.

I hate to beg for help, but I'm at the end of my rope. I recently acquired a 1988 'Vette that had been garaged most of its life. I'm in the process of restoring it, but one issue I absolutely cannot solve are the wipers. The wipers only activate at the top setting on the switch, and then they barely move, raising up about an inch before going back down repeatedly. I replaced the transmission, motor, motor cover/board, and nothing is physically blocking any mechanical components. I have no idea what could be causing this. I don't know for sure if the switch would cause this or not, and I'd like to know for sure before I burn more money on these things.
Has anyone ever experienced this issue before?

I had an intermittent wiper not turning off problem the other day,
the motor has a park switch turned out the contacts were loose.
They push into the two motor male spade terminals, the female spade terminals were quite loose making a bad contact.
Simply crimping the female spade terminal does not work they are fragile and break easily, used a piece of tin to push into there to secure it. Works perfect now and the wipers stop / park every time.
Something to check on your old wiper motor..

iNSIDE THE MOTOR OR MOTOR HOUSING, OR DO YOU REFER TO THE WIRES RUNNING OUTSIDE OF THE MOTOR TO CONNECT TO IT?

when the wiper motor plastic cover is removed, the two contacts can be seen to the right of the large gear.
the two long strips have a contact point that connects to the cover, they are part of the park witch on the motor.
