When i use my windsheid wipers it wont trun off? and how to adjust wiper not set right? thanks

I read the above answer and it feels on target for the realignment although I have never done a vette.

However, if the other question is that they run and won't turn off the most common problem is the "smart stick". That's the multi-function stick on the column that includes the wipers.

Should be available at most parts store reasonably. If you want to take a risk on that you can most likely find a you-tube somewhere describing it.

Good Luck!

Try this steps to adjust your wiper.
1. Place the keys in the ignition, turn the keys to accessory mode (key-on/engine off), and make sure the wiper motor switch is in the off position. Turn the ignition switch to the off position and remove the keys. The wiper arms are now in their parked position, although may not be properly aligned.
2. Access the bottom of the compromised wiper blade arm. You may have to open the hood or remove the wiper arm cowling (refer to the owners manual for the removal of the cowling on your specific vehicle if required).
3. Locate the retaining nut at the bottom of the wiper arm assembly. Some models will have a protective plastic cap covering the nut. Other vehicles may have a hinged cover that is part of the wiper arm itself. Pry the cap off with a straight-edge screwdriver or unsnap the hinged cover by prying it up from the bottom of the wiper arm with the screwdriver to reveal the retaining nut.
4. Hold the wiper arm stable with one hand and remove the nut with the ratchet and a socket with the other.
5. wiggle the wiper arm gently with one hand while gently prying the base of the arm off the splinter wiper arm stud. The stud has a small spline that holds the wiper arm in the correct position unless otherwise compromised. The wiper arm will feel secured to the stud, but the combination of wiggling gently and prying with the screwdriver will work to remove the arm.
6. Place the arm back into the splined wiper arm stud by positioning it in the off position. some vehicles may have a wiper arms stop that the arm rests in the off position. If so, make sure that the wiper arm is resting against the wiper arm stop when replacing it on the stud.
7. Replace the retaining nut and tighten with the ratchet socket. repaet this procedure with the other wiper arm if desired.
8. use 2 sets of pliers to bend the wiper arm back into position if the wiper arm has been bent. Hold the wiper arm with one set of pliers to anchor it and use the other set to bend it so the wiper is perpendicular to the windshield. If the arm is bent too badly,replacing the wiper arm maybe a more viable option.
9. Inspect the wiper blades.check them for tears in the rubber blades, dry cracking or flimsiness.Replace the wiper blades if necessary.
