I've never had to replace one on a Santa Fe, but the washer nozzle (jet) usually just clips into the scuttle trim (the black plastic part at the bottom of the windscreen). Doing the job by the book, you need to remove the scuttle trim and disconnect the washer hose off the bottom of the nozzle, then press in the clips that secure the nozzle and lift it out of the trim. But to remove the scuttle trim you'll need to remove the windscreen wiper arms (which are often rusted on) and there will be some plastic rivets that will need to be removed too. It's not that big a job....if the wiper arms cooperate.
If it's the same as AUTOSPARK suggests follow his advise.
Best practices for requesting help:
* If you haven't done so fill in your vehicle info and profile page. Shows up to the left
* Be sure you are in the correct forum for your vehicle.
* Do a search for your problem. A lot of stuff has been asked and answered.
* Do not double post for the same problem.
* Give the model year....Engine size...transmission type (auto or standard)
* VIN number can be very helpful.
* Did you buy the vehicle new, if not, how many miles were on it when purchased? How many miles on it now?
* Describe the problem the best you can.
* Tell us what has been tried, if anything.
* If the vehicle has been to a repair facility it would be nice if you can scan or take picture of the bill and attach it to the post.
* If your vehicle is under warranty you should have the dealer check it out. If it's an issue they see many times they will generate a safety recall or do a TSB. This is how they know.
This information can save a lot of time and get you the answers you need much faster.
