Re: 97 Sentra wipers won't wipe
They have grooves that are supposed to keep them in there. If not, you can place a little bit of silicone type glue to the grooved shaft. If it has no grooves, the only solution is to replace the motor with a known good one. If the wipers freeze during cold winters, some people don't wait to defrost the windshield, they turn on the wipers as soon as they turn on the car. this will cause damage to the wiper motor and or the wipers.doing this enough times the small grooves on the motor shaft will wear down.

Pull off the wiper arms when the motor has turned off and the wipers at rest. Realign the arms in the position desired and do a test with a mist of water on the glass. The gear alignment is critical to the way the arm rests when in operation and when at rest.
you may have a bad set of splines either on the wiper transmission arm that the wiper arm attaches to or the splines in the wiper arm were it makes contact with the attaching point that you tighten.look closely as if these splines are bad it won`t matter how tight it is it will slip.you may have to get a new wiper arm(or used)or replace the wiper transmission depending what you find.assuming of course you mean the wiper will not move at the speed it should be compared to the other arm
It could be a relatively easy fix or it could take some effort. First, try repositioning the wiper. By flipping up the end cap of the wiper arm and backing off the set screw that holds it on the wiper motor post. Remember, what position it was in by placing a piece of tape on the windshield. Pull the wiper arm off by pulling it off in line ith the angle of the wiper motor post. Take a close look at the splines of both the wiper blade arm and wiper motor. If either is damaged you will have to replace that component. Estimate the amount of adjustment you need and reinstall the wiper blade arm that amount in relationship to the piece of tape. Tighten set screw and try it. If it still does it but less then repeat the process until you get it adjusted correctly. If there was no change thing it could be the wiper motor and that takes some effort to replace.
Ok, from the start. The motor is connected to a bar that runs to the wiper posts. These post are what the arms of the wiper blades are connected to. The arms hold the wiper blades. if you just had new arms and blades, they may not be on the post all the way. If not, and your sure the motor works, then the bar has fallen off at either the motor, or the wiper post. That's all there is to it
you will have to remove the panel under the wiper arms at the bottom of the windshield remove the wiper arms by popping off the little caps at the bottom of the arms where they used to pvvot. remove the nuts that hold on the arms and pull the urms upward then unsrew the panel to get inside to see which part broke off. these wiper trnsmission artms are ussually only available from the dealer.
Most likely you will have to replace the wiper linkage from the center pivot to the left or drivers-side wiper pivot. The plastic piece in the linkage gets brittle over time and breaks down. To save a hassle in the future, replace both linkages. It should be under $20.00 for parts.
