My "intensive" washer pump does not work - no power is getting to the pump connector accroding to my multimeter, so the next place to look is the relay (relay #IX, p/n 928 618 113 01), then the switch I guess. Rain-X now makes a bug-removal fluid that I was going to put in the second washer system.

Does anyone have a test procedure for the intensive washer pump relay?

Is there a way to jump the socket to see if the circuit downstream from it is working?

Any help is appreciated! Thanks!

Yes - remove the relay and make up a short wire with a 1/4" male quick disconnect on each end. Connect the 87 & 30 pins on the socket together - (plug in 87 first & remove it last for safety). The pump should run if it does the relay or its inputs are suspect...

Pin T Should be high when the washers are on (BTW intensive only works while the main washer are on... you knew this right?) Pin 15 should go high when the intensive switch is pressed.

Thank you Alan. The amount and depth of the immediately-available technical knowledge on this forum continues to amaze me!

No, I did not know that the intensive washers only work with the wipers on, but I suspected that might be the case and tried them while running the wipers as well (still no power to the pump connector).

When you say "Pin T Should be high when the washers are on" you mean that there should be 12VDC between it and ground, right?

If I'm not getting power to Pin T or Pin 15, I guess I have a problem at the dash switch, in the wiring, or between the wipers and the relay input, right?

Another project for this weekend!

Alan,

This is great - I jumped 87 & 30 and got voltage, but I couldn't figure out what you were talking about with pins 15 and T - there were only three pins on the relay. Hmm...

So as I'm examining the relay, I see the part number, so I decide to check it, and go figure - it's the wrong one!! I glance at the relay chart and notice that it's the p/n for relay XI, not IX. I check the relay in socket XI, and sure enough - it's my intensive washer relay! Is de-switcharoo'd them and my intensive washer pump hits it on the first try. :-)

Incidentally, I did not have the wipers running already when I tried this - when I hit the intensive washer button, the wipers came on automatically for 3-5 strokes.

Thanks so much for your help! I never would have found this without your helpful procedure!

Are you sure you have the right relay? Look at the labels for the relays here is an arrow that point to the relay socket - the relationship is not always a fixed orientation...

Yes, I checked the socket labels closely. I learned that lesson already!

And that's my point - the PO or someone misread the labels and arrows and put them in the wrong sockets.

So what does relay XI interference suppressor do?

Double dog sure. I checked both relays - labels and sockets. Someone messed up, and I fixed it.

So again, do you know what relay XI interference suppressor does?
