I'm having a problem with my wipers on my '69 Camaro. When I first turn them on, they drop down aprox. 2 inches before starting back up. I took off the cowl, removed the arm from the housing and made certain that I have aligned the housing marks with the shaft marks and that doesn't seem to help. They don't go down first now, but when I turn them off, they don't go completely to the bottom. They stop exactly where I turn them off. I've done a search and can't seem to find any answers. Please help. Thanks! Bill

Have you had them apart or changed the motor?

Could be the motor is worn out? Or if you have them apart or changd motors, you may have the arms our of phase with the motor.

If that doesn't work, how about just removing the wiper arms, then turning on the switch and back off. Put the wiper arms back on where they should be when in the parked position, and try it again. Maybe this will set a good starting point.

I took off the wiper arms and made certain that the housing marks aligned with the shaft marks. I turned the wipers on and then back off again. I then Put the arms back on and they still went down 2 inches first before starting upward. I then took the shaft off and turned it 180 degrees. Now the the arms don't go down first, but they'll stop wherever I turn off the switch. They're not returning to neutral (or down) position. Any other suggestions. It's driving me nuts!!

Sounds like motor problems. It sounds like your wipers act the same way as if you turned off the key. They stay where they last were. Wiper motors park themselves if you turn off the switch no matter where they were.
I haven't been insde many of them but there may be a cam and a switch inside that controls the park/off function.

There's one more thing to check before you go replacing the motor or linkages. It's been brought up a couple times in the forums before.

You said you just put the motor back on. One of the attachment points is also a GROUND for the motor to the firewall. Or there's a raised bump very near one of the mounting points that makes contact with the firewall. Both have to be free of paint at the point of contact. If not, all kinds of wacky schtuff will happen.


Take a look.

Very good point HSJ. A wiper motor operates by switching ground to it through the switch. When you turn off the switch it needs a ground to complete its last cycle and park. It gets that through the frame. Otherwise it stops right where it was. It may go down before up when you turn it on again because it has't completed its last cycle.
Last thought I have before picking on the motor again is: You do have a small ground strap from battery (-) to the right inside fender? This is the body ground that the motor needs.

I just removed the wiper motor and there is no contact point where the motor contacts the firewall. There are 3 rubber grommets where the motor bolts on and an oval rubber seal where the motor goes through the firewall. The metal on the motor does not and cannot touch the metal on the firewall with this setup. I ran a ground wire from the motor to a ground on the body and it didn't help anyway. I thought maybe the yellow wire was supposed to go on the bottom of the front terminal, so I changed it with no success. Any other suggestions? Here's a picture of my wiring setup on the motor. I highlighted the colors on the wires in this picture. There is yellow, light blue, dark blue and black. Does mine seem to be wired correctly? Thanks! Bill
P.S. I do have a small ground strap from battery (+) Not (-) to the right inside fender?

Are you sure you have the correct motor? While many will look alike, they have differences.

If you got one from another Camaro, only 68 and 69 and 70-78 non-concealed wipers will work. But many other years and models will interchange but they can't be the concealed wiper type. The list is long or I would type it here but some cars up to 1980 will fit. The fact that they were dropping down 2 inches make me think you have a wiper motor for concealed wipers and you don't have these.

The grounding on the wiper is from a grounding tab that contacts one of the three bolts that connect through the grommets. If your tab is missing, that could be the source. However, elcamino's comments sound reasonable. Even if you did not replace the wiper motor, maybe someone else did.

It is possible that this is the wrong motor.
This may sound like a dumb question but why would a concealed wiper motor go down 2 inches when I initially turn on the wipers before starting the upward swing? I thought a concealed motor would drop the 2 extra inches at the end of the cycle to conceal the wipers. I don't see any grounding tab. I'll take the motor back off and check again. I may just order a new motor and see if that helps. I just wanted to check all other options before spending the money on a new motor. Thanks! Bill

I just looked at my 69 and the yellow and blue wires are opposite of what your photo shows. Now I have not had my car together for 20 years but the photos i have taken are opposite of yours. The motors might be different. Mine is marked
5045572
Type E Delco Products
12 V Rochester N. Y.

Also the metal strap that others are referring to is located at the upper right hand mounting hole looking at the motor from the front of the car. The metal strap appears to an integral part of the grommet.
Yours might be there but painted over.

I can email you a photo of my motor if you want.

Hope this helps

My wiring matches just as the pic above shows and the wipers work properly... I don't have functioning washers yet though. Bill please double check that ground strap you spoke of;

<BLOCKQUOTE>quote:</font><HR>P.S. I do have a small ground strap from battery (+) Not (-) to the right inside fender? <HR></BLOCKQUOTE>

Our cars are negative ground and connecting the positive terminal to the fender isn't advised. The positive should go to a junction block mounted on the core support I believe. Maybe it's on your fender...

I just pulled my motor back off and there is positively no metal strap or anything protruding at any of the 3 mounting holes. With the rubber grommets in place here is no way for my motor to contact the firewall at all (metal to metal). Here's the info from my motor assembly:
5045441
Type E
12V
Delco Products
Rochester N.Y. USA
Is this the correct wiper motor?


P.S. I do have a red wire from the positive battery terminal to the fender right above the battery. It does look like some sort of junction (small plastic block with a bolt stud). The red wire goes to that junction
and hooks up to that single terminal. There is also another red wire running from that terminal to a wiring harness across the radiator core support over to the voltage regulator and horn relay. I can't actually see where it hooks up. There is a pigtail hooked on the negative terminal that hooks to nothing. What's that for?

Redline that NEGATIVE little wire that is hanging needs to be bolted to the edge of your fender as mentioned in other posts. That ground the battery to your whole body insuring ground for elec. equipment like your wipers. There should be a small sheetmetal screw within reach of that wire, make sure the end is clean and that the screw is not rusted. Screw that wire on the fender and try the wipers again. If it still doesnt work right, then tie a ground wire to your wiper motor and the firewall so the ground is complete and try again. I think the ground is your problem. Let us know.

I just hooked up the negative wire to the body and it didn't change anything. I also ran a jumper wire from the wiper motor housing to a ground and it didn't make any difference either. Still have the same problem. When I align the marks on the wiper arm with the marks on the housing, the arms drop down 2 inches on the initial startup. If I change it around 180 degrees, the wipers still stop wherever they are when I turn off the switch. Also when the wipers are on the off position, I can grab a wiper blade and move it manually. Is this common?
I think I'll try another motor. Thanks! Bill

My yellow and blue wires are also opposite the photo on the first page. I have both fully functional wipers and washer pump. The rear connector has the yellow and blk w/yellow tracer wire on the top terminal, the light blue one is on the bottom, and there is a separate black wire on the lower rear terminal, just like in the picture.
