It will work, just not as desired. When activated it seems to get stuck and struggle to complete its swipe.

Pretty common. It starts and stutters right? I did a write up on how to fix this on AW. You need to remove the motor and fix a couple of contacts internally.

By the way is your avant melange?

Melange, is that a color? If so, it is a '99 and tirerack lists the color as bamboo. I'll check the tech files on AW. Thanks

there is a ball check valve that goes bad. this causes the stuttering and skipping. mine had a nice breakbeat thing going.

i replaced the entire motor assembly for about $140 bucks. it was a piece of cake. believe it or not, this piece was actually less expensive than on the outback. that one was 10 bucks more. i did them both in under an hour.

remove the rear wiper arm from outside the vehicle.
open the hatch and carefully pull the inner hatch cover off.
unhook the wiring and replace the assembly.
the rest is the reverse of disassembly.

The rumor is that it's a ball check valve. Rather than spend $140 I decided to investigate. As far as I know a ball check valve is used in fluid and this is an electric motor. The issue turns out to be a pair of electrical connections that let the motor know where it is in it's rotation. The springs get weak and the contact just needs to be bent out. About 45 min. later I saved $140.

is your write up "Fixing Slow Wipers" by Tom Kliem?

My rear wiper started up at 53,000. Gotta love Audi's electrical components.

thanks for the link, printed it off. 53K miles isn't much, makes me wonder how long mine has been doing it for. Had 70K when I got it and was doing it then.

I used to get that stutter and shake as well. Hadn't changed the rear blade in a few years cause I don't use it much. Finally replaced the rubber blade and the metal piece that holds the blade - works perfectly now... not a skip to date.

Mine's great some days but on occasion will be flaky. I just deal with it :)

Cool another melange avant. I thought I was the only one.

I agree. Not only is it awesome to see so many other avant owners, but also a couple other melange ones.

I have a replacement blade, which I was waiting to install after the fix. Instead, I'll replace first to see if it fixes the problem.

And as of last week ... here is another Avant owner (and loving it)!
Get the details on my arrival here:

But back on topic, I have been seeing a similar problem. Only my arm actuates fine, the sprayer isn't getting anything. I am praying for a disconnection in the line, somewhere. I did find a leak on the chasis underside, just below the B-pillar. If not, I'll use the info in this thread.

Right on! Let us know when it is posted. My under carriage check yielded no leaks, nor were there any near the tank. So any more info at this point would be terrific!
