I am restoring a 1959 Brookwood. I installed a 1959 Two Speed Wiper Motor with a pump. But when I installed the wiper arms, the wiper must not be in PARK. So the wiper when stopped is point upwards towards 10pm (when standing in front of the car). If I install the wiper arm parallel to the bottom of the windshield and turn on the wiper switch, the arm travels downward towards the cowl and pins itself against the body.

So I know it is not in park. I have followed the directions at the following link https://www.chevytalk.org/fusionbb/showtopic.php?t...

but still cant get the unit to park itself.

I am disconnecting the triple wiring harness that plug into 1, 2, and 3. and then connecting the jumpers as stated in the link. When i jump 1 and 3, the unit just spins and does not stop until I disconnect the jumpers.

Are there different procedures to test with the unit installed in the car? Or any other ideas?

I'm sure someone can verify if this is the cause or not, but if the car originally had a 1-Speed and you are changing to a 2-Speed, there is a difference in the Wiper Transmissions. There are 1-Speed Transmissions and 2-Speed Transmissions.

There is likely a troubleshooting section in the shop manual for wiper issues. For a 59, you should have a 58 shop manual plus 59 supplement plus a 59 assembly manual, if not get them, they are invaluable.
If it’s not the wiper transmissions, you may find your problem in the motor via the shop manual.

I do have both manuals. I have referenced them and used them. But they dont go into any detail if the transmissions are different or not. They do talk about the two motor and how to test them. I am following the directions as stated above and it does seem to park (ie stop in the same spot). But when I connect the transmission arms, it is the definition of insanity... doing the samething over and over expecting a different result.

Does anyone have any experience with changing a single speed to a dual and can verify that the trans is different? Would hate to go chasing that windmill if I dont have to...

The transmissions are very different, and are marked for easy identification/ They will either have a large "1" or "2" cast into the base. Number refers to speeds of motor used.

ok mystery continues. I checked the markings on my car and the wiper transmission have 2R and 2L but the motor that was installed was a single speed. Not sure if the motor was to original or not but given how rusted the screws were, it looked like original as there was a sealer over top of the screws. I am doing a search on ebay and see that a 2 speed cam part that installs on the motor points in the opposite direction vs the single speed. So I am thinking the cam arm is the part I need to solve this puzzle.

I Might be wrong on this but check the cam on top of the motor i have seen a few variations and that might throw them out

Mystery solved. The cam arm that installs on the 2 speed motor was the issue. The single speed arm squared slot that slides onto the motor is angled differently than the 2 speed. The single speed will point to the 10 o'clock position while the 2 speed points to the 2 o'clock position.

I purchased a 2 speed cam arm installed it and all is finally good. Feels like I am the first person to ever encounter this issue. I doubt that I am. But scouring the internet for an answer proved fruitless. I hope this post helps others who may encounter this issue.

So for a two speed set up, is it an entirely different motor or is it the cam arm?

If you have a single speed wiper (much smaller in size) and want to install a 2 speed wiper motor (much larger), then you also need a 2 speed wiper cam arm as well.

While holding the cam arm in your hand with the round pin facing up at 12 oclock and the sloted at 6 oclock, then....

The single speed cam arm slot that bolts onto the motor points to the 10 oclock position. While the 2 speed cam arm points to the 2 oclock position.

You will also need 2 speed wiper transmission arms (they will have a 2R and 2L on them). And of course a speed switch

Not sure I understand your question. How do you know which one you have...

Have what?
Motor?
Switch
Cam Arm
transmission arms?

Picture would simplify this. But I don't have access to upload them. I can email them to you if you send me your contact.

The 2 speed wiper (old pic of my 59) is visibly different, single speed is square from this angle,
Steve Hackel in Chicago area restored this one and recently did my 67 but sounded like he was about done doing them?
