The rear window sprayer on my 2 month old ID.4 is not dispensing washer fluid as expected. The front sprayers work and I believe that the front and back share the same washer fluid reservoir. When I push the wiper stalk to clean the back windshield, the rear wiper comes on but there is no washer fluid getting dispensed. Any ideas or suggestions on how to fix this would be appreciated. Thanks.

That worked! I put the car in reverse, and pushed the stalk and the wiper came on AND washer fluid was sprayed out. I then put the car in park and tried again and it worked. I'm not sure why I had to first do this with the car in reverse in order for it to work.....but I'm glad its working now. Thank you!

It's a long way from Tipperary .... and from the "frunk" reservoir to the rear sprayer. There's only one pump for both the windshield and rear glass/backup camera with a valve(s) directing as required (typical most any vehicle setup).
As @Pascal well cites if you haven't used the rear in a long time, or not at all, it takes some time to get the fluid back there (unlike his avatar which is most always operating ;)).
