So my daughters 1999 vw cabrio had the wipers stop working while driving back to school.
So, the car is not here, it's 3 hours away, with an EE student.

She has a meter, not much else.
There is a trusted vw shop up the street if it come to that.

She checked the fuse, it is fine.
I need to get her to test the relay and I have no clue how to do that without it in my hand.

Does anyone know how to test a multi speed wiper relay?

Also, if we can determine with a jumper in place of the relay, if the motor works or if the motor is bad, that would be an even simpler way to test the relay.....by proving the motor works.

I don't think that is the delay wiper repay. The one from my Passat donor car is twice that size.

Might not be the right color codes but here is my relay.
