Windshield motor has 3 wires, can I use a 2 wire universal pump for a replacement? how to hook it up?

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.

My database only shows one wiper motor. Did you check voltage and ground, anywhere? Check the wiper fuse for voltage, hot all the time, use test light. At the wiper motor, dark green wire is voltage for lo speed. The purple wire is voltage for hi speed, Turn on key, turn on wiper switch, probe those two wires for voltage, use a test light. That bottom black wire off wiper motor, in diagram, is ground, check that also. If good voltage and ground with no wiper action, I suspect the wiper motor. There are codes for wiper, manufacturer codes, check for codes. good luck

Just replacing parts isn't the way to fix this problem , viewing wiring diagrams too see what all is involved in making the wipers work is . Then using a digital volt ohmmeter to test electrical circuits . Also looking at factory service info. to see how it's suppose to work.

Under system click on body & accessories , then under subsystem click on wiper/washer . Click the search button ,then click the blue link. Looking at the wiring diagram i see two fuse's an two relays that are controlled by the BCM - body control module . Also hooking up a scan tool that can read BCM DTC'S - diagnostic trouble codes could be helpful . The wiper switch is a input to the BCM - the BCM will energize the relays to turn on the wipers.

Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper 1 relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIPER/SW 10A fuse
• WIPER 25A fuse

Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper 1 relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay contacts to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.

It should be a short circuit or a bad relay. Good luck.

Switch is bad.

A 3 phase motor replaced by a single phase motor has to be connected to phase one and neutral. You're going to use more power that way. How long does it run before shutting off? Is the new pump getting hot? Have an electrician determine which wires are the phase hot and neutral. Hooking up 2 phases without a neutral will trip the thermal overload in the motor.

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.

If you are just talking about the windshield washer pump/motor that squirts water on the front windshield, there is no separate fuse for that pump. If you are talking about the front windshield wipers themselves then the fuse for that (including the washer pump) is located is the fuse panel inside the vehicle down below and to the left of the steering wheel. Below is a diagram of the fuse layout (first picture) and I marked the 10 amp fuse for the system. As I said if you are talking about the pump/squirter motor there is no separate fuse. Inside the wiper motor itself (located basically on the firewall on the drivers side) is an internal microprocessor as well as an internal relay for that pump. If the processor or the relay is bad, both are internal and the whole wiper motor assy. has to be replaced. It's one complete unit. There is a chance that the pump motor itself could be bad. In the second picture is a breakdown of the washer fluid reservoir. In order to get access at it which is where the washer pump motors are located the right front wheel and splash guard have to be removed. I have marked the 2 washer pump motors which are mounted on the reservoir. I cannot tell you which motor is which but the one for the front has 2 wires at the connector (a black & white wire and a black wire) The rear pump motor has a violet & light green wire and a black wire at its connector. That's how you can tell which one is which. You can test the motor by either pulling it out and applying direct power and ground to it to see if it engauges or while someone is engauging the washer inside the vehicle while you are down there, see if you are geting power at the black and white wire. Check that wire while it is disconnected and using a good separate ground. If you are getting power make sure the black wire is geting a good ground. If all is good (ground & power) than more than likely the pump motor is bad. If you have a power supply problem at the black & white wire than you are looking at most likely a bad wiper motor assy but check for an open power wire from the wiper motor to the pump motor. It's not quite as simple as it used to be. The wiper motor on your vehicle has like a mini computer in it. I'm gonna say the washer pump motor is bad which is the most common. Hope I was able to help and that I didn't get too technical on you but things are not like the old days with separate motors (wiper and washer).

The hatchback Accent has two windshield wipers--one on the front and one on the hatchback so the pump can run to pump fluid to them each separately. You need a specific pump for that. I've written up a step-by-step tutorial on how to replace the pump and have a link for the correct part at my website: Replace Windshield Washer Pump on 1999 2005 Hyundai Accent Share Your...

#1.. replace horn
#2.. check power & ground to W.W. pump.. if present.. replace pump.. If not, repair wiring.
#3.. replace door lock/unlock actuator.
