Wiper Motor Help

[Andrew]

I have a two speed wiper switch that is labelled 30, 31, 31b, 53,, 53a and 53b. The switch checks out on all positions on my meter according to the rules.

• Switch off: 31b connects to ground (via its mounting to the dashboard), 30(+) connects to 53a
• Slow speed position: 31b is open, 30(+) connects to 53
• High speed position: 31b is open, 30(+) connects to 53b

I have a four terminal motor, only 3 terminals are connected and 53 and 53b have been jumpered together.

The wiper motor works but only ever at a single speed, could this explain why?

Could I have a broken speed on the motor or was this a common thing to do? Anyone seen this before? Is slow speed so slow that its been omitted?

   many thanks,

Andrew

which wiper motor is it? you might have a later one that's not meant to work with the dash mounted switch

You may have a 67 single speed.
Are the contact spades all in a row?

Are the contact spades all in a row?

All in a row and there's 4 of them.

That's a single speed 12 volt 1967

Ah, that would explain it.

What does a multi speed one look like?

They have contacts side by side rather than a straight line.

ps I've just put my spare N.O.S one in the for sale section.
