1984 Camaro Sport Coupe
I have a manual, 4 actually, Clymer's, Chilton's, Haynes and my Big Blue 2 1/2" CHEVROLET "Service" Manual. Unfortunately Big Blue does not cover the wiper motor removal. The Tab says to refer to the "BODY" manual.
Haynes has the best illustrations and directions. I've had a look at the rear wiper link, to motor crank arm. Took a picture of it so I could enlarge the image and give myself a better sense of the attachment points before I begin disassembly.
The crank arm is attached to the, "Double Keyed" (my term, shaft is ground down to a rectangle) shaft, by means of a nut.

Now I get to where my problem is.
The rear wiper link is attached to the crank arm... How? It looks like a press fitting of some sort. I really don't want to break something.
This rear wiper link then attaches to the arm/linkage by means of two small nuts (loosened but not removed) that permit adjustment. The linkage then moves the wiper arm spindle.

Has anyone done this?

 

I seem to recall that the wiper motor has an arm on its shaft with a nut that holds it on.

3 screws hold it to the car.

It's REAL SIMPLE. You'll figure it RIGHT OUT when you look at the parts instead of those inscrutable "diagrams".

 

Well, come the week end, I'll give it a go, CAREFULLY. The shaft nut you speak of is correct, as are the 3 bolts that hold the motor in place. It's that pesky attachment of the motor arm to rear link that has me scratching my head. Once done, I'll come back to this thread and detail what I found. If I figure out how to leave some pics I'll do that too.

 

I don't think you have to disturb that to change out the motor. Might have to adjust it afterwards though.

All it is, is a bar of metal with a hump bent in it, that bolts over a ball stud and can be slid along the piece it's on, to adjust the range of travel. It's all really quite simple. You'll see, might look weird and intimidating on paper, but in real life, it's not much more complicated than a ball of mud.

 

Thanks for the reply. Look forward to getting this done.
Last winter, I very often drove the car in the rain, less the wipers. Sometimes they would just quit, or if I attempted to use the washer, that would make them quit.
Living here in the Great NW, right here on the coast, it rains a-lot. The surf is only a half mile from the house. At night, following a storm, you can easily hear the waves crashing the beach.

Hey !! how do I post pics ? I recently did a timing chain swap in my driveway (no fancy shop here) and took some pics. The job and or the pics may be of interest to someone

 

If that's all that's wrong, you might not need a motor at all...

The whole thing is mounted on 3 rubber bushings that those 3 screws go through, for noise isolation I guess. That means that the motor is insulated from ground, and must be separately grounded somehow. That was done by using a little brass strip across one of the bushings to provide the electrical connection. Problem is, as the rubber gets old and compresses and wears out, there is no longer any pressure holding the frame of the motor against the brass, and the connection ceases to be connected, and the motor stops working. They're REAL BAD about quitting, or starting back up, when you hit a bump.

If this sounds familiar, try running a short piece of wire from one of the screws that holds the motor together (NOT the mounting ones) to one of the ground screws on the firewall nearby, before messing with changing out the motor.
