Does anyone else have this problem. I have a 71 Cutlass (442 clone) and the wipers do not go down all the way. It does not have the concealed wiper motor(round one). It has the square wiper motor. Even so, I do not think the park position on these should be so high. I adjusted the linkage to the max to get them as low as I can. Is there anything I can do to change this. I tried removing the wiper arm, and turning it a little... but these have key ways in them and you cannot change it. I have see wiper arms with splines and those you could turn a bit to adjust.

I believe you'll need to change out the wiper motor. The cam used to park the wipers is different from the hideaway wiper one.

The Fisher Body Manual has a whole chapter on the wipers, and how to adjust them. Google wildaboutcars.com, and look for Olds publications.
BTW, I looked on Wildaboutcars and couldn't find the manual, If you can't find the info, PM me with your email and I'll scan the wiper arm adjustment and email to you.

Yeah, your park position switch is out of sync.

Don't ask me how to fix it, but it's probably possible.

I always just reach under the workbench and grab another wiper motor when something like this happens...

There is only one adjustment on this unit and I have it set to get the blades down as far as possible. Changing the motor will not change anything. There is no park position switch that I can see or accessible. If I manually turn the motor one revolution the blades will not go any lower that shown in the picture. If the arm on the left side was 1/4 " longer, the blades would be down all the way. So mechanically they cannot go any lower. I do not know what gives. Surely they were not designed to stop at that position.

Please post a photo of your wiper motor. It should be a depressed-park motor, but maybe someone found a way to replace it with a non-depressed-park motor.

More likely, you are unaware of how the wiper motor works, as is implied by your comment, "There is no park position switch that I can see or accessible."
You should heed the advice of dc2x4drvr and read the chapter on your wiper motor in the Fisher Body Manual. There is more movement possible in that motor arm than you realize.

=================
actually, that sounds exactly like the behavior of the square wiper motor.
I believe only the round ones turn backwards in order to execute a lower PARK position when de-activated. Please READ the chassis service manual section on the wiper motors. It goes into all such detail.

MDchanic

They don't actually turn backward, but when the park finger settles in its notch and activates the park switch, and the eccentric takes a half a turn, it can look like it (if I recall the function correctly - I have to re-read it every single time I want to understand the darned thing).

Here is picture of wiper motor. I do not have the manual and could not find any info on wiper motor or adjustments for it. MDchanic said there is more movement possible in that motor arm. If there is, I just do not see how.

That's the wrong one.
Let me see if I have one in the
shop and shoot you a pic...

tru-blue 442

This is the one that should be there.
The one you have looks like a 66-67 to me.

The rectangular mother was standard A body cars, round motor was for optional (hidden) wipers..
According to my 1971 fisher Body Service Manual, the "only adjustment of the wiper arms is to remove them, and rotate to the correct position" better take another look at your wiper arms, they're serrated, not keyed..

MDchanic

Yup. As anticipated, you've got the non-depressed-park motor.

You can get a replacement at the junkyard or the local auto parts store.

I am beginning to think you are correct. I do not think this is the right motor. When I bought the car, the wipers were disconnected. I think they just through in any ole wiper so it looked like it was there. I need to find a new one somewhere.

MDchanic

As I said:

Please take a look at my earlier post..the only adjustment to your wipers (with the rectangular motor) is to take the wiper arms off, and position them lower!
Why do you think the motor is the problem?

HLS

I took the wiper arms off and you cannot position them lower. The wiper arms have a key way. They do not have a spine where you can turn it a bit.

I think the adjustment needs to be done on the arm that is on the back of the wiper motor. this arm attaches to the wiper assy. Wiper arms(the ones with wiper blades at the end) is not adjustable. Take a look on the back of the motor.

Post a pic, I've never seen a key way on an Olds wiper arm..

dc2x4drvr

Maybe this will help..

dc2x4drvr

Wiper arm adjustment, sorry for lousy images from my ipad..and it's sideways.

dc2x4drvr

No..the arms are adjustable..

My 72 does not park the right wiper fully down. It gets close. My 67 does not have wipers at the moment, and I'm guessing they will just stop at the bottom position and not park?

HLS

Here is picture of wiper blade shaft and wiper. It has a key way. I also have 2 pics of wiper motor. Top and bottom sides. I see no adjustments anywhere.

MDchanic

To reiterate:

That is a non-depressed-park motor, and you need a depressed-park motor.

Now that you've done the work of removing it, get the right motor and put it in.

I have a used if you want, $35 plus the ride.
It will need another plastic nipple for the hoses.

This thing is driving me crazy. Here is the whole story. When I got this car it did not have concealed wipers and the switch was not right either. When switch was on HI, wipers were off. When switch was on LO, wipers went slow, When switch was off, wipers went fast. Finally figured out that two wires were switched as shown in picture with the 3 connectors shown. I have corrected that and now the switch makes sense. Off is Off, Lo is Lo and Hi is Hi.

I purchased a wiper motor unit with concealed wipers and want to install it. However, it does not have the same type connectors on it. I need to know how to wire it up. See the picture with the old unit. I labeled each wire going to it and what it does. When the ignition is turn on, the yellow wire gets 12v. The washer wire (Blue) is simple, it is grounded when you activate the washer. The wiper runs fast when the Light blue wire is grounded and the Black wire is floating (not grounded). The wiper runs slow when the Light blue and black wires are grounded.

Now look at new unit. What wires should go to terminals A, B and C. I also ordered an electric pump which I believe mounts on top of the cam shown and covers it up. I am not sure what the Yellow and Green wires are really for.

If you have a wiper motor like this, what color wires are on terminals A, B and C. The Yellow and Green should go to pump, but are there any other wires attached to the pump.

Tru-blue 442, your wiper motor looks very much like my new one (I paid 60.00 for it but no washer). Do you know how it was wired. Yours ever has a washer on it. Maybe I should buy yours and return the one I bought. Do you know if it works and does the pump pump.

H, this came from a 71 Cutlass
I parted years ago. It has been
in the shop out of the weather.

I will try to hook it up to my harness
in the 66 and see. Wish me luck, I don't
know if the harnesses are the same.
I would think that the diafram on the pump
is probably dried out though being 42 yrs old.

tru-blue 442

Worked like a champ.
I even heard the pump trying to kick in.

Not sure if these two pics will help or not.
Mine is a 66, but has the same wiper motor.
