I hope somebody can help me figure out how to wire a 2002 to 2006 Acura rear wiper motor so it will operate my front wipers. I have a 1949 Willys Street Rod with vacuum wipers. I have worked out the mechanics of adapting the electric motor to replace the vacuum motor.
I am not very good with the electrical part of the transition. I can get the electric motor to run but I can not figure out how to wire it so the park feature works when you cut the switch off. I am using a simple on/off switch. I have attached a wiring diagram for the 2002-06 Acura RSX Wiper Motor.
Please see attached file. You can also email me at: [email protected].
Thanks
Bill Butler

It looks like from that diagram there is a park circuit that you need to keep the power on until it parks. if you look at teh off position on teh switch it is supplying power to a different wire

Bill, It looks like you're gonna need a single pole double throw switch to operate it. (SPDT)

Wire #1 to the ignition switch with a 10 amp fuse inline.
Wire #2 to chassis ground.
Wire #3 to the common terminal on the SPDT switch.(center terminal)
Wire #4 to one side of the SPDT switch that you wish to use as the OFF position.
Run a wire from the other side of the switch to chassis ground(ON position).

Thanks for the quick reply. I am not good at DC electrical stuff. I am including a drawing and asking you to finish placing the wires where they need to go. I hope you can help with this.
Thanks

Here is a modified sketch showing basically what OLNOLAN suggested. With the ignition on, there is power to the wiper motor, but no ground connection. The switch regulates the ground connection, not the power. Flip the toggle switch up, and a ground connection is completed and the wiper motor comes on. Flip the toggle switch down, and the wiper parks. Once parked, move the toggle switch to the middle or OFF position.

wipers

Sorry guys, I'm usually online in the mornings. I'm an old timer and if you wait on me to do a drawing with a computer program. ................................... Hoptup32 did a damn fine job on the drawing, but the center off isn't necessary. When you switch it to the off position, then the limit switch in the wiper motor breaks the circuit, until you start it over again by switching it back on.

Oh, I forgot to add that the limit switch appears to be optical, requiring power to operate, thats what that extra hot lead is for that you see going into the limit switch.

Thanks Hoptup32 & OLNOLAN
I will try what you sent me and also what OLNOLAN sent. Maybe between the 2 of you guys, I will get it to work. I will let you guys know tomorrow after I hook it up.

Hello Hoptup32 & OLNOLAN,
Well I tried the wiring as indicated on your drawing and the motor runs fine but it will not go back to the park position when I shut it off or toggle it in the opposite direction. By the way, both of you gave great directions and the drawing was really easy to understand. Could there be something wrong with the park feature on this motor?
Do you have any other ideas or is there anybody else out there that can help.
Thanks

I can see as OLNOLAN indicated, the toggle switch in the park position with the yellow wire isn't necessary. Just turning the wipers off will switch the ground control over to the limit switch.

Assuming that the limit switch is fine and it is receiving power from the green wire, I would suspect that there is an issue with it seeing a ground connection. After you switch the normal wiper operation to OFF, the motor will continue to operate by seeing a ground connection thru the limit switch, until such time as the limit switch is triggered to disconnect the ground connection.

The ground connection labeled #2 is for the limit switch, do you have that connected separately to a good ground source? The Acura wiring diagram shows a second ground connected to #2, I'm not sure what that is about?

If its not the ground source to the limit switch, then the only other possibility is the limit switch is bad. However, I wouldn't think that they would have a high failure rate.

If memory serves me right the center post on the switch is stationary while the wiper in the switch moves between the top and bottom post dependent on the position of the toggle arm, therefore in my opinion the ground wire should be on the center post.

Thanks OLNOLAN
Yes, I checked that out. Thanks for the reply. All of you guys suggestions are really helpful. I will let all of you know if I get it to work.

Thanks Hoptup32,
I will double check the ground situation out. That extra ground you mention that is shown in the Manufactures diagram, is showing that I need to ground the wiper motor also. I am grounding the motor and the switch and ground wire number 2. So everything is grounded well. I am thinking that the switch in the drawing, you sent, should actually have the ground wire in the center. I will try this next. Really appreciate all the help I am getting on this.

Hello T-Bucket23,
Yep, I did do that and thanks for the reply. Maybe all of us working together will get this solved.

Been busy with work, got a few minutes to try and figure this out. 1)When you switch to the park position, where does the wiper stop?
2)Does it stop in the same place every time?
3)DON'T use a SPDT switch with a center off position. Use a ON-ON, not a ON-OFF-ON.
4)Disregard my initial thoughts of the park switch being optical. Its just a cam operated switch, the extra positive wire on the switch shorts(discharges) the windings when it reaches the park position to make the motor stop faster(not coast to a stop).
5)I'm 99% sure the wiring will work the way I recommended, unless I'm missing something in that 1%. LOL I've been known to miss something.
6)As mentioned, make sure the wiper motor is well grounded.
7)I'm thinking that the motor is not "clocked" in the correct position to make the wiper park where you want it to.
8)Is the wiper arm shaft splined, whereas you could move the arm to the position you want it to park at? If so, take the arm off, then turn the wiper switch on and then back to the off(park)position and let the motor park itself. Then install the wiper arm in the position you want for park.

Let us know what you have in regard to the questions. I'm like you, between the bunch of us we can figure this out. If I had the car in front of me it would be easier, long distance no touch troubleshooting is tough.

OLNOLAN,
(1) When I cut the switch off it stops in any position. Never in the same spot it starts in unless I keep flipping the switch until I get it back to the park position.
(2) Did you mean a ON-OFF switch? If not, where would I get an ON-ON type?
(3) Motor is grounded directly to the Battery and I am running the Hot directly from the Battery positive.
(4) It does not have splines on the shaft so I can place the wiper arm in any position.
(5) Could you do a pencil drawing of how you think it should be wired, then send it by email to: [email protected]? I will send you a drawing that has the components and all you have to do is pencil in the wire routes.
