Where is the rear wiper relay located? If I turn the delayed function on I can hear a clicking that sounds like it's coming from under the dash and also back at the wiper motor but I don't see a relay. Manual is no help and I have found the Chilton's sucks period.<p>Also, brake fluid is disappearing but the only spot I can see a potential leak is at some sort of sensor that comes out of the bottom of the booster right near the abs module. What is that module?

Re: rear wiper relay location/ disappearing brake fluid (tailgunn)

# 204, upper right in the panel above your left foot.<br>I'm 99.9% sure that this is the rear intermittent wiper relay.<br>The regular and intermittent modes feed the motor from the <br>same contact points in the relay. So, a few more details, please.<p>Does the <I>regular</I> wiper mode work?<br>Does the washer button ( at the end of the stalk ) work?<br>The washer button should squirt as long as you hold it,<br>then wipe for a few seconds after you let go.

I guess I have to pull a panel to see that relay? Wiper does not work at all but the washer squirts. Is there a relay at the motor as well. Thanks!

Re: (tailgunn)

Nope, no relay in the back. (But if you hear something, it might be the motor. More later...)<br>The pump motor is out front at the washer fluid tank and is pretty much independent<br>from the intermittent wiper relay. It has power from fuse 33 whenever the key is on.<br>Fuse 33 also provides power to the relay, so if the pump works, it should have voltage.<br>When you push the button, you ground the other side of the motor and it pumps. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> <br>( It also triggers the relay for a timed wipe cycle )<p>The relay MAY be bad. That fits. If it only kinda works, has crappy contacts or something, <br>the motor might be getting low voltage and make a little noise, but not move. <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> <p>The other thing that fits is bad wire at the hinge. Or a bad motor altogether. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0"> <p>SO...I'd start by testing the two wires that feed power to the motor.<br>One goes hot when you turn the wiper on (Wiper Hot)<br>and the other is power to park the wiper (Wiper Park).<br>The parking voltage should be there whenever the key is on.<p>Choose any easy place to check voltage as close to the motor as possible.<p>The connector that you want ( and involves the easiest reach ) is in the LH D pillar.<br>Pop the tweeter out and look for a 2 row, 14 pin connector.<p>Wiper hot = Green/Orange = pin 8<br>Wiper park = Yellow/Violet = pin 9<p>See whatcha get...That should get you started! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <p><br>

Ugh.. I hate electrical trouble shooting; mechanical I can handle, but I bought this car to haul my race bike and instead the darn thing is cutting into my racing budget so I better get at it... I already have the hatch panel off for the rattle kit and I have switched motors already. The first motor never did anything; the second motor moved about an inch the first time I tried it and never moved again. I'll start with the connector at the hatch panel. So, I need to set my voltmeter to 20, hit the hot wire and a ground wire and it should show some voltage?<br>Thanks for the help.

Re: (tailgunn)

You got it. Just pick up a chassis ground and get to checkin'. <br>With the just key on, you should see voltage on Wiper park.<br>With the key and the wiper switch on, you should see power on Wiper Hot.<br> Glad to help! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Ok, I tried this- it should be around 12 volts right? On delay mode I get about .84 from one wire, don't recall which and I get none from any other wires. I'm just using the motor lever arm for a ground since it's bare. I did test my tester against a courtesy light just to make sure I had the right settings and I got a reading of around 12 so I know I have the tester right.<br>Is there a way to bench test the relay?

Re: (Chilled Man)

I think Chilled has the right idea here. Fresh Relay.<br>Plug in a known good one and see if that does it. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

I'll check tonight to see if I can find anything for sure that says which relay it is otherwise I'll just have to go from BEJ's guess that it's 204.

I confirmed with dealer that it's 204 but I wonder if I can switch in the front wiper relay to see if it works with that? That would tell me if relay is bad.

Re: (tailgunn)

Different relay and different pinouts...<br>I'd stick with a known good sub for the back wiper.
