No, that's OK, you go ahead and enjoy it all to yourself... BTDT, and as grumpy as you still are they must have bounced your nuts off the table a couple times and squeezed 'em in a vise while they were at it...

Andre,
Test the "I" pin connection to the relay - probe into the Central Electric panel with the relay out. When in intermittennet mode with the ignition on - you should see 12v on this pin - if not this is your problem... This pin tells the relay to go into intermittent mode.

This pin is driven from the wiper switch via a diasy chain on one side of the interval pot. I'd pull the interval pot and make sure you have it connected and that one side has 2 connections - this is the switch driven side - test it there too. The other side connects to directly only to terminal R on the relay.

It could be a switch issue... next step is to directly test the switch output.

BTW buy the VW digital relay instead and get rid of the silly pot - a worthless piece of crap even when its working (don't ask me how I really feel about it...)

Hi Alan,

Do you have a VW part number of an OB

SharkSkin

Andre, more info on the VW relay here. It works the same on any shark. I didn't mention it, because I figured you had already spent more for the Porsche relay than the VW unit cost.

Alan,

We are now at the switch :-(

I has zero voltage and the pot is connected correctly.
The single wire from the pot goes to R correctly.

Class is still in teach

Andre, did you check the peas... uh.. pins on the CE panel that I mentioned?

Andre Hedrick

My stupid has returned, so where is the CE panel ?
I thought that was where the relays live.

Bump for a response Alan and SharkSkin

CE is Central Electric. See post #2 on the thread. If you're unsure of the nomenclature, I'll give you an example: C6 on the CE panel is the third connector from the left(A-B-C), pin 6. Pins are arranged as follows:

4 8
3 7
2 6
1 5

In the pic below, I am pushing terminal J2 out through the back of the panel.

I dont know if you were looking but up under the bottom of the dash is a speed wheel for the wiper delay make sure this has 2 wires going to it and also see if reversing them will make the wipers operate correctly, sometimes the winding on this potentiometer breaks then its time for a new one Ohm it out

Some sprinkles today, and my intermittent wiper mode was AOL.

Searched and found the VW relay mode.

I'll check what Mrmerlin said and if it's not that...

I think I'll give it a try.
