Search JagBits or other parts houses. The fitting is easy to find - less than $10. I bought two because it doesnt look like a very durable part...
This is a super easy 15 minute repair.
- Open the bonnet and remove the 3 firewall beauty panels (I found a giant mouse nest under the master cylinder cover so it's good to look in there once in a while)
- On the wiper arm base, pry up the cover with your fingers, unscrew the wiper bolt and remove the wiper
- Unscrew 5 screws on the plastic windshield base cover
- Clip the zip tie holding the washer hose to the bottom of the broken fitting
- Remove the broken fitting with a quarter turn
- Reuse the rubber washer (unless it's perished) and install the new fitting
- Reassemble all and attach the wiper hose to the new fitting
- Voila! Wipey wipey squirt squirt!
