Headlight washer problem

[Traurig, Scott R]

	Thanks for the reply, Huw. If you read my post carefully, you will
see that I actually don't have the manual yet, just have it on order, but
thanks for complimenting me on my "manualess" diagnostic skills and efforts.
I probably wouldn't need to ask for help at all, but without the manual I
find it tough to diagnose things. I guess I'm a "read the
manual/instructions" type of guy.

	Anyway, I hope you are right about the headlight sprayers only
running for 1 second. I don't have any friends with Audi's and am located
more than an hour away from the nearest Audi dealer, so I can't just go look
at another working one. Can someone else confirm this? If so, then I can
re-concentrate my efforts on the motor and any possible obstructions, but I
don't hear the motor run. I can probably pull the hose off the motor and
squirt some compressed air through it to check squirter operation and for
obstructions.

	Anyone ever change a squirter motor on an A4 (or can look in the
manual for me)? It appears that it just pulls straight out of the washer
reservoir. If I'm fast enough will I need to drain the reservoir first? :-)

	Best regards,

	Scott

	Admittedly my experience is with systems of a decade prior to your
car,
	but often there is a lot of continuity to how Audi does things.

	pump motor resistance sounds right.  did you try hooking it up the
other
	way (12/gnd switch?)  Anyway, assuming for the moment that it is
dead
	since it sounds like it (and why??)... check inside it for
obstructions
	maybe?

	on my 90Q, the headlight washers *do not* appear to stay on as long
as I
	hold the stalk.  They turn off pretty quickly - I think - and one
second
	might be about right.

	if you had access to a known working pump it would be interesting to
see
	what happened.

	I *think* the pop up sprayers are pressure driven, maybe someone who
	*knows* can verify?
