Re: driver side windshield wiper doesn't work
Only proper fix is to replace. might could put some epoxy in the wiper arm(very small amount) and reinstall let it set up without using for a while. remember if you do this it will never come off again!!!

Remove the wiper arm by taking the nut off the end of the post coming through the base of the wiper. turn on the wipers and if the little post is turning back and forth with the other wiper, then you need a new wiper arm. the little serrations on the inside of the arm's base get stripped, usually from turning the wipers on when they are stuck to the windshield by ice. if the little post is not turning then you need a new wiper transmission. you will need a repair manual for that.
Unless there's something wrong with the linkages; which I can't imagine...
It almost has to be the nut is loose on the passenger side.
Make sure the wipers are off and the igition is off.
According to what you say, the driver's wiper is in the correct "parked" position.
On the passenger side wiper arm, pop off the plastic cover at the pivot point of the arm.
Underneath, there is a nut. Loosen the nut a little. Wiggle the arm while pushing the arm down. Hold arm in place and tighten the nut. Replace cover.
If that doesn't take care of it, you may have to remove the arm completely and check the tapered spline underneath. Either the arm or the post spline may be stripped. Maybe try a new arm, as the post will be more difficult to replace.
if the passanger wiper stopped working AND the drivers side is still working...one of two problems. the easiest is to pop off the black cap at the base of the wiper arm, under it you will find a nut. check to see the nut is tight. turn the wipers on and observe the post that the nut is on, if it is turning, then the nut needs to be tightened or the spline on the post or wiper arm is stripped. If the post is not turning, then most likely an arm on your wiper assembly has come off, remove the wiper arms remove the black plastic cowl and you will find the wiper arm assembly.
good luck. HTH
the wiper arm could need to be replaced
being loose could have have worn the hole in the wiper arm
or the splines on the wiper transmission maybe damaged
i would try a new wiper arm first
use BLUE LOCTITE on the threads and TORQUE the nut to (22 lb ft)
hope this helps
I recently had the same problem of the drivers side wiper not working. My boyfriend (a mechanic) took the windshield cowl off and looked to see what was going on. He originally thought that maybe something had slipped off. I'm going to describe what he found in layman's terms. When you take off the wiper blade arms from the wiper transmission assembly unit there are these silver colored nubs with grooves on them (one for each wiper). What he found was that on mine the grooves were stripped so that the wiper on the drivers side wouldn't catch and go across the windshield while the other wiper worked fine. What we think that happened is that I left the wipers on when I shut off the car and since we had a huge snowstorm the wiper transmission bound up and stripped the nubs when I turned on the vehicle the next day and let it warm up. I had tried for the past week to find a used replacement wiper transmissions assembly but was not successful. I just ordered the part from my local Hyundai dealer at a cost of $180. I will at least save on the labor, as my boyfriend can handle that part. If you try to get the part used, be careful. There was a product change mid-year. Prior to June 2004 (If I remember correctly) is one part number and Santa Fe's manufactured after that date is a different part. I needed the earlier Santa Fe part. You can look at the body panel between the front and back doors on the driver's side for the production date of your vehicle there is a metal decal with the vin, your color codes, and other information.
