Symptoms

•Windshield wipers continuously operating
•Wiper control stalk has no effect on wipers
•Possible electrical burning smell
•Wiper motor may be making a constant noise
•Fuse for wipers may be blown

Diagnostic Steps

1
Inspect the wiper control stalk for any visible damage or malfunction.
2
Check the wiper fuse in the fuse box for continuity and replace if blown.
3
Use an OBD-II scanner to check for related error codes that might indicate electrical problems.
4
Test the wiper relay by swapping it with a similar relay from the fuse box.
5
Disconnect the wiper motor connector and check for voltage supply when the wipers are in the 'off' position.
6
Examine the wiring harness for any signs of wear, corrosion, or short circuits.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the wiper fuse using the diagram on the cover.
Pull the fuse out using a fuse puller or needle-nose pliers.
Inspect the fuse for a broken filament; replace it with a new fuse of the same amperage if necessary.

3. Replace Wiper Relay

Identify the wiper relay in the fuse box.
Remove the relay by pulling it straight out.
Insert a new relay of the same type, ensuring it is seated properly.

4. Testing and Replacing Wiper Motor (if necessary)

Reconnect the battery terminal.
Turn on the ignition and test the wipers.
If they still do not turn off, disconnect the wiper motor connector.
Use a multimeter to test for voltage at the connector while the wipers are in the "off" position.
If voltage is present, replace the wiper motor by:
- Removing the wiper arms using a socket set.
- Unscrewing the motor mounting bolts.
- Disconnecting the motor from the wiring harness.
- Installing the new motor by reversing the steps.
