If the windshield wipers on your 2002 Corvette won't shut off, it could indicate a problem with the wiper control switch or a malfunction in the wiper motor circuit. Here are some troubleshooting steps you can try:
Check the wiper control switch: Ensure that the wiper control switch is in the "Off" position. Sometimes, the switch can get stuck or malfunction, causing the wipers to stay on. Try moving the switch back and forth a few times to see if that resolves the issue.
Inspect the wiper motor relay: The wiper motor relay controls the power supply to the wiper motor. If the relay gets stuck or fails, it can cause the wipers to stay on. Locate the wiper motor relay in the fuse box or relay panel and try replacing it with a known working relay of the same type to see if that resolves the issue.
Check the wiper motor circuit: The wiper motor circuit may have a short or an electrical problem that is keeping the wipers engaged. Inspect the wiring harness connected to the wiper motor for any signs of damage or loose connections. Use a multimeter to check for continuity and proper voltage in the circuit. If you are not familiar with automotive electrical systems, it is advisable to consult a professional technician or a qualified electrician.
Disconnect the battery: As a temporary solution, you can disconnect the negative terminal of the car battery to stop the wipers from running. This will disable other electrical components as well, so it's recommended as a temporary measure until the issue can be properly diagnosed and repaired.
Did the wipers stop in the up position? If so it may be a blown fuse or a defective wiper motor. Have you looked at the fuse-box? Did you mean that the wipers swipe the windshield correctly and then when the wipers shut off they stop in the wrong position. If this applies then inspect the wiper transmission. There could be worn/loose linkage between the wiper motor and the wiper arms. Also if the wiper motor was just installed. The clock position may be wrong. Please let me know if this information helps. If not please write back, leave more details, and I'll do my best, good luck.
Your windshield wipers come on because of the position that the wiper control is set. Wipers will come on intermittently if you set it for light rain or snow or it can be set to come on immediately and fast for hard rain or snow. Please make your windshield wiper adjustments by turning the control knob or lever to the desired position.

Windshield Wiper System
The windshield wiper system consists of :
Windshield wiper motor (17508) (F-type).
Washer system.
Windshield wiper control module.
Turn signal and windshield wiper switch (13K359).
The windshield wiper control module is:
Located at the instrument panel fuse panel.
The windshield wiper motor is:
Attached to the cowl top extension (021A36) .
Connected to windshield wiper mounting arm and pivot shaft (17566) .
The turn signal and windshield wiper switch features a:
Rotary wiper switch.
Push type washer actuator.
OFF/Low/High Speed
Has a two-speed, permanent magnet, three brush electric windshield wiper motor .
The windshield wiper motor has a brush rigging that permits selection of low or high speed.
When the turn signal and windshield wiper switch is in the LO position, the common brush and the blue/orange wire brush are used, and the windshield wiper motor operates at low speed.
When the turn signal and windshield wiper switch is in the HI position, the common brush and the white wire brush are used.
In HI position, electric current will bypass a portion of the armature winding causing the windshield wiper motor to operate faster.
When the turn signal and windshield wiper switch is moved to the OFF position, the windshield wiper motor will continue at low speed until the park switch outer contacts open.
When the park switch contacts open, the windshield wiper motor stops in the park position.
Interval
When the turn signal and windshield wiper switch is in the interval position:
The wipers make single wipes separated by pauses.
The rotary switch is on the end of turn signal and windshield wiper switch .
The length of the pause can be set from approximately 1 to 17 seconds.
Length of pause decreases as the rotary switch is rotated away from off.
Length of pause increases as the rotary switch is rotated toward off.
While in the interval wiper mode:
It is normal to hear a slight click at the beginning of each on/pause cycle.
NOTE: When using interval wipers, the first wipe may not occur until after a pause of up to 17 seconds.
This is a commoon problem with what is called the "Park pawl stop". The tab is most likely bent and needs to be re-aligned, then the wipers need to be re-timed. This re-timing can be a little difficult, although the re-aligning of the tab is failry simple.
