First of all, sorry for my english.
I have a problem with my camaro third 87. The wiper and wáter doesn't work properly. I don't know if the problem IS a fuse o what.
Thanks in advance.
I have been reading a many problems with the wiper in ou cars. The most common IS the problem with the ground wire. Could you explain me where put the new wire? I think that one side between the the brackets and the wall but the other side I don't know where to put It. Please could you put a mark on the photo?
You need a ground wire between the body of the motor, which is somewhere behind the big black plastic blob in the pic, and the firewall. The motor itself is round, maybe 60cm diameter, and hangs down below the cast chinesium thing you can see between said blob of plastic and the firewall. There are usually 2 screws, maybe 3, that go all the way through the motor, and clamp it together. Loosen one, put a wire with a fork terminal under it, and the other end of the wire to the screw with a braided ground strap under it.
That may, or may not, make yours work; but it's important to correct the factory's malfunction of the copper clip across one of the rubber bushings holding the chinesium thing to the firewall, which depends on the rubber to maintain contact. Well, GUESS WHAT ... rubber won't do that. Even if the chinesium didn't corrode, as yours obviously has (they all do, it can't be helped), the cold-flow of the rubber makes the whole system fail. The inevitable corrosion just makes it happen faster and more certainly.

Thank you so much. I will try to do It next week. You are the BEST

I have found this image. I think that the best way to put the new wire is using the fork terminal on the Bolt with orange arrow.
Am I right?
Just loosen one of the screws that holds the motor to the casting with the gears in it, and put your ground wire there. The screws are in the end of the motor. It might be easier if you take the whole thing off of the car first. It's held on by those 3 screws holding it to the firewall and one nut holding the wiper transmission arms to the shaft that the large gear turns.
I realize you said the picture you posted in post #5 with the black plastic cover removed isn't yours, but, if you HAVE removed the cover on yours, please know that it needs to be properly indexed upon reassembly, lest you destroy the works under the plastic cover, thereby ruining a pretty much "unobtainium" part. See on this pic where it says "Drive Pin" with some arrows? That is where the metal pin you have marked in your pic by the red arrow needs to go, and not in that small slot that trips up a lot of people when they reassemble it, if they didn't read the "Drive Pin" position indicator with the arrows first.
The Wiper Motor in your first picture looks like it's an 88-92 style motor ?? ( The 84-87, style motor uses a different plug.)
84-7 Wipers do not have a Ground wire to the assembly,... it gets grounded to the body via a ground strap in 1 of the mounting bushings. The 88+ wiper motor has a Ground Wire at the motor.
If you need to ground the motor,... ground it at the body mounting bolt I've circled in GREEN.
Ground here:
*** If you have not removed the wiper motor cover,... DON'T - LEAVE IT ALONE until you learn more !!
Here is the wiring schematic for the 88 Wiper Motor:
DO NOT try to use a mounting screw to ground it. 2 reasons. First, the original ground which used the rubber isolator to hold tension on the ground strap, has already shown you how ineffective that is over the long term: that's why you're having to replace the ground in the first place, so no sense including the same failure in your repair attempt. Second, that's the blob of chinesium that corrodes, and guarantees failure over the long term as well.
Ground it from one of the screws that holds the MOTOR together. NOT the chinesium blob, which can't provide a good connection to a ground wire OR to the motor, and above all, AVOID requiring the rubber to hold tension on the connection.
