Wiper motor and switch

[nqkjw]

Hey all
Need some help and advice that is probably best from you blokes as the wiper motors and switches in our Aussie Valiants are nothing like the US ones.
Firstly what I know.
I'm pretty sure my 70 challenger (10/69 build)originally had a standard dash.The dash frame and wiring support this assumption.
Someone has fitted a rallye cluster to it.
Now from what I can work out you could get 2speed,3 speed or variable speed wipers.Is this correct?
The wipers in the car aren't working but I tracked the problem to the switch.
When they worked,though,they only had one speed.
The dead switch appears to be a variable speed switch.
I plugged the switch out of a 72 Dart Swinger I have and they worked but still only one speed.
The Dart Swinger switch appears to be a 3 speed.
I then tried a switch from a wrecker 67 Dodge Phoenix (What you'd call a 67 Plymouth Fury)which was a variable switch and it worked but still only single speed.
After that I'm a bit stumped as to what to check next.
Is there any way I can tell if my wiper motor is 2sp,3sp or variable?
Would the wiring in the car be incompatible to the wiper motor fitted?
Do you absolutely need the right switch with the right wiper motor and right wiring?
I'm in the dark.
Any help and advice appreciated.
Below is a pic of the wiper motor if that's of any help.

Hi Ken,

I sounds to me that you have a variable speed wiper switch and it may be broken. Meaning that the resistor coil is open and is why you would only get one speed. If you could confirm the switch part number as being either a 2770380, 2947404, 3488764 or 3488773 would be a big help and we can go from there.

Hey,thanks for the quick reply Slotts
You're lucky I'm still up.
Or I'm lucky.
It's 1.30am over here!!!

The non working variable switch from the challenger is p.n.2770380

Are the wiper motors different or just run at speeds dependant upon the supplied voltage from the switch?

2-speed wiper motors are different than the variable speed/3-speed that you have.

2-speed wiper motors are different than the variable speed/3-speed that you have.

Obviously the 2sp motor looks different if you can tell mine's a 3sp/variable just by looking at my pic?

Your ok with that motor. The variable switch and the three speed switch controlled the same motor. The three speed just had fixed resistance points rather than a sweep across a coil.

I can help you with that switch if you like. If you could send me an email at jsrestorations@rocketmail.com would be good and I can send you some pictures.

Haha...my next question was going to be "where's the best place get one" and then I noticed your sig

Should I email the addy in your sig?
When I try to go to w.jsrestorations.com I get a site called GoDaddy

Hey Slotts,
Haven't heard back from you.
Did you get my email?

Hi Ken,

I did get your email and I replied on the 27th. I just resent the email again.
Let me know if you receive this one.
Thank you for letting me know it didn't get there. Hope it makes it this time.

Yeah mate,I got that one but I've sent one since.
Looks like it was mine that didn't go through!!! LOL
I'll send it again and this time you can let me know if it comes through.
