How do you replace the windshield wiper motor?

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:

1. 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.
2. 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.
3. 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.
4. 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.

The is the symptom of a defective wiper switch.

Depending on what your trying to do with wipers, I'd want to see voltage on the gray and or purple wire. See the black wire at the bottom that is ground, a good ground is a must. Hey Jeff, I'm not trying to bug you. If I spend time trying to look up info, I'm going to post it. I don't care if the question has already been answered. Have a good day.

When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

Windshield wiper motors are generally easy to replace. You need to remove the windshield wipers and take off the small grill panel above the hood and under the windshield. You should see the motor in there. It simply unbolts and unplug the electrical connector and replace it with a new one.

The windshield wiper motor is a smart wiper motor with an integrated electronics module. The internal components of the motor are the high/low relay, washer pump relay, and the run/park relay and associated electronics.
The windshield wiper motor receives its inputs from the windshield wiper/washer switch. These signals are ground reference signals. When the switch is placed in different positions, various input signals are selected and sent through circuits to the motor. The windshield wiper motor module identifies these selected input signals and activates the motor to the selected function.!
Your probably going to need a new wiper motor ! ! ! But you should always test before replacing parts !

WINDSHIELD WIPERS

It can be faulty wiper motor or blown wiper control fuse.

Do you hear any kind of noise when you starter the wiper function. If yes then fuse is ok, but issue is wiper motor.

If no movement at all and no noise then its blown fuse or shorted/loose wiper control wiring: -----

Thanks.

why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.


don't have 1983 info, but here is 1994:

Section 01-16A: Wiper and Washer System, Ranger/Explorer 1994 Ranger and Explorer Vehicles Workshop Manual
DESCRIPTION AND OPERATION Windshield Wiper System, Ranger/Explorer The windshield wipers are actuated by a permanent magnet, rotary-type electric windshield wiper motor (17504) . The two windshield wiper pivot arms (17526) and windshield wiper blades (17528) are mounted on a pivot shaft, one at each side of the windshield. The windshield wiper mounting arm and pivot shaft (17566) are connected to the motor by windshield wiper adapter and connecting arm clip (17531) . Ranger and Explorer vehicles are equipped with an interval wiper and washer (IWW) system featuring a lever-type turn signal and windshield wiper switch (13K359) mounted on the steering column. The IWW windshield wiper governor (17C476) uses a relay contact to control current to the windshield wiper motor . The governor electronic circuitry controls the contact to supply current to windshield wiper motor . A rear wiper/washer system is available on Explorer vehicles. The rear window wiper system consists of a windshield wiper motor mounted inside the liftgate (40010) , an articulating windshield wiper pivot arm and windshield wiper blade , a windshield wiper/washer switch (17A553) and an inline circuit breaker. The front electric windshield washer system consists of a control switch, integral with the turn signal, a windshield washer reservoir (17618) and windshield wiper motor and the necessary windshield washer hoses (17A605) , windshield washer nozzle jet and brackets (17603) and attaching parts.
