1. Check the Switch:
* The Obvious: Make absolutely sure the switch is in the "OFF" position. Sometimes, it can seem like it's off, but a slight nudge might be needed.
* Wiggle the Switch: Gently wiggle the stalk of the wiper switch. A loose connection within the switch itself could be causing the problem. If wiggling it makes the wipers act erratically or turn off, you've likely identified the culprit.
2. Fuse Check:
* Locate the Fuse: Consult your owner's manual to find the correct fuse for the windshield wipers. It's usually a relatively high amperage fuse.
* Inspect the Fuse: Carefully remove the fuse and check it for a blown element (a broken wire inside). Replace it with a fuse of the *same amperage*. Do *not* use a higher amperage fuse.
3. Relay Check (More Advanced):
* Locate the Relay: Your owner's manual or a repair manual will indicate the location of the wiper relay. It's usually a small square or rectangular component in a fuse box (under the hood or inside the car).
* Swap the Relay: If you have a spare relay of the same type (check the markings on the relay itself), try swapping it with the wiper relay. If this fixes the problem, the original relay is faulty and needs replacing. If you don't have a spare, you can try finding a similar relay in another part of the fuse box (if it's not critical), but don't swap randomly.
4. Multi-Function Switch (The Stalk):
This is the most likely culprit if the previous steps didn't work. The multi-function switch contains the wiper controls and can become internally shorted or have a worn-out component. This usually requires:
* Replacement: You'll need to purchase a new multi-function switch (also called a wiper stalk or turn signal stalk) from an auto parts store. Installation can range from relatively easy to more involved, depending on your mechanical skills. Consult a repair manual for your specific vehicle model year to get detailed instructions. It will involve removing the steering column shroud and carefully disconnecting the electrical connectors.
5. Wiring Issues (Least Likely, Most Difficult):
This is the least likely cause, but if the above steps fail, a short circuit or damaged wire in the wiring harness could be at fault. This requires tracing the wiring to identify the problem. This is a complex task best left to a qualified mechanic.
Important Considerations:
* Safety: Disconnect the battery's negative terminal before working on the electrical system to prevent accidental shocks or short circuits.
* Repair Manual: A repair manual specific to your 1998 Chevy Malibu is invaluable for detailed instructions and diagrams. These can be found online or at auto parts stores.
* Professional Help: If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic. Continuing to drive with malfunctioning wipers is not advisable, especially in inclement weather.
By systematically following these steps, you should be able to pinpoint the cause of your constantly running wipers and get them fixed. Remember safety first!
