Why won't my wipers park properly - 71 Charger

[71 Bee Man]

G'day guys. Hope someone can offer some advice.

I was reading with interest one of the other threads about the restoration of wiper motors and I found it interesting that they can be put back together in the "park" posdition and that there's a knack to installing them.

Basically......when my wipers operate, they hit the stainless trim at the bottom of the widshield, which - apart from being really annoying - can't be any good for the blades. Then, when I turn them off, they don't park properly but rather sit a couple of inches too high and must be moved down by hand.

What should i do ? Is there any techinical info on the net I should be looking at ? Is this a common problem ? Does anyone know what I'm talking about and how to remedy it ?

And yes.....I did have the wiper motor apart to clean it up, but I thought I put it back together the right way.

2 speeds or 3 speeds ?

if is 2 speeds, just need to replace, fix or reassembly the parking cam stuff what is an external piece. Maybe in fact just oiling will fix. I have found just dissasemble, clean and grease ( light grease ) will fix the stuff.

If is a 3 speeds will need to rebuilt the motor... but you can do it by yourself really, getting the kit. I got this kit ( just $5 ) to get ready everything when I upgrade from 2 to 3 speeds and does come COMPLETE with gears and all:

becarefull, some kits comes just with plate, some others just with gears, or shaft. Maybe need couple of internal parts, but just in case I advice get it complete, like this:


The ebay link I got you is that same stuff. The pic I'm inserting is the ebay auction I won, and in my hands right now. Same PN.

The three speed wipers in my 71 Charger have never parked properly. Five years ago I bought a rebuilt motor from Jules the wiperman at Carlisle and they still don't park.
So Nacho, your telling me that Jules sold me a bad rebuilt?

[Nacho-RT74]

mmmm Who knows Maybe used wrong kit, or placed wrong. Remember 3rd gens parks down the hood but not earliers. They could use the wrong kit ? maybe. Or bad assemblied ?

I'm checking the kit instructions and the plate does have three positions depending of car where will be mounted. Could be that.

Anyway, I'm still not familiarizated with 3 speeds motors. will know when I have one in my hands ( coming soon, already paid ).

Nacho,

what about the wiring on the motor - is it possible to get repro wiring kits ?
I have the correct 71 Wiper Motor, but the wires are cracked and joined by wire joiners....not a good look.

I think they are being reproed now, but just 2 speeds since they are plugged on both ends... 3 speeds are solded on motor.

Anyway you could get a new 2 speeds harness, cut the plugs and sold on 3 speeds motor without problem. Wires are the same colors, just 2 speeds have an extra jumper wire on external ballast resistor that wouln't use on 3 speeds.

Or if you think are able, make by yourself the harnes... is not hard, just get brown, green, red and blue wires, crimp new male terminals ( females too if is 2 speeds ) and sold and that's all. tape and VOILA!!! with 10 bucks will save maybe $60-80 (if that's the price ).

Anyway, whats the exact problem ? wipers just stop where they are when you turn off the switch ?, or do they get on lower area of glass without hide ?

If is the #1... yeah maybe is one of the wires, the one that feeds the motor to spin on oppposite direction and then park when is internally shutted off at certainlly point. This wire has power allways when off.

If is #2... then is some of the mechanical sistem ( internal on 3 speeds, external on 2 speeds )

G'day Nacho,

the problem I have is that when my wipers are on, they continually "wipe" down lower than the stainless steel windshield trim. I'm not sure if they're meant ot do this, but it is very annoying.

The other problem is that when they are turned off they try to park, or "house" themselves, but stop short by about 2 inches.

Peter.

[Nacho-RT74]

then is not an electrical problem is mechanical
When they are on, just be run throught the glass without EVEN TOUCH the trim. Then parking, motor spins on opposite direction, gets to top but about two inches before the regular track they used to and then hide down the hood.

You didn't end to tell me if is 2 or three speeds. If 2 speeds is a piece of cake to fix. maybe won't even need to buy anything, just check, dissasemble, clean, lube and assembly again ( correctly ).

If 3 speeds, will need more job but I don't think hard to do really. I replaced the internal gear and shaft on my 2 speeds once and only need to blow the original rivets and use screws when joining again.

pay attention on links I provided and will be able to do it.

Not sure if you currently have 2-speed or 3-speed wipers.  2-speed wiper motors are sold rebuilt by Napa and others for something like $79.  I don't think it would be worth it to try to rebuild one of these when you can get a "new" one for this little money.  Now if your motor is working OK but just wipes too far and won't park correctly, then that's a different issue.  If your motor is OK, would the wipers be too long for your application?  Are the wiper arms attached to the pivots at the proper position.  Are you sure that the items under the dash have never been messed with.  The wiper motor output shaft has a bellcrank attached to it.  And there is a plastic washer attached to the end of the bellcrank that attaches to the arms under the dash going to the wiper pivots.  Is all that stuff stock?  If not, then some of this could be a problem.  Someone else will have to answer as to parking positions issue on a 2 speed.  I don't know if it's adjustable.  It is on a 3 speed. 

[Nacho-RT74]

3rd gens are completelly dif assembly than earliers. You don't have acces to crank and motor down the dash. And as stated on 2 speeds parking cam is a separated assembly from the motor. Is really attached to the bellcrank.

I bought a remanufactured 2 speed at Advance for around $60 with no exchange. I just had to put that ballast resistor looking terminal strip on it and reuse the rubber grommets to make it an exact swap. They seem to park fine now. But after watching the commercials and seeing the assembly line, it appears they never parked quite right. Even the service manual has the arm positioning a good distance from the trim.

2 speeds parking problems are not related with motors

I had an almost identical problem  The issue was that I had mine 180 out in the linkage.  I turn the bar at the back of the wiper 180 degrees and reinstalled the wiper linkage.  All worked great again.

Note the rectangular section behind the threaded section.  This is what I had the rotate around 180 degrees

G'day again guys,

haven't checked this thread for a while because I've been busy, but in response to everyones question.....my wipers are 3 speed.

Hi Peter,

I Have a 68 Charger with a 3 speed wiper ( I'm not sure if it is the same style as yours?) But I had exactly the same problem with my wipers.

In my case the rivet holding the cam assy to the top plate had worked itself loose and had made the hole it was originally inserted into larger and elongated...This caused the cam to move around where ever it wanted to go inside -  not allowing my wipers to park properly. The rivet is right in the centre of the circular plate partially hidden by the wire in this pic...I ended up putting a screw in where the rivet was to stop the cam gear spinning...
Cheers
Danny

then does look is time to rebuild!!!

is a job you are able to make by yourself with the needed parts. Open it and chek inside. It could be just some loosen or needing grease
