1. Check the Fuses:
* Location: Consult your owner's manual for the location of the fuse box (usually under the hood or dashboard). Find the fuse(s) related to the wipers (often labeled "WIPERS" or with a wiper symbol).
* Testing: Visually inspect the fuse for a blown element (a broken wire inside). If blown, replace it with a fuse of the same amperage rating. Don't use a higher amperage fuse, as this could damage the electrical system.
2. Inspect the Wiper Motor:
* Location: The wiper motor is typically located under the hood, usually near the base of the windshield. You might need to remove some plastic covers to access it.
* Testing: Listen for any unusual sounds (grinding, humming, clicking) when you turn the wipers on. A completely silent motor likely indicates a problem. You can try tapping the motor gently (with the ignition OFF) to see if it frees up – this is a very crude test and shouldn't be done forcefully. A failing motor usually requires replacement.
3. Examine the Wiper Switch:
* Location: This is inside the car, usually on the steering column.
* Testing: Make sure the switch operates smoothly. Try all the wiper settings (intermittent, low, high). A faulty switch needs replacement.
4. Check the Wiper Linkage:
* Location: This is the mechanical system connecting the motor to the wiper arms.
* Testing: Visually inspect the linkage for any broken or loose parts, bent arms, or anything obstructing movement. Lubricate any moving parts with a silicone-based lubricant (WD-40 is NOT recommended for long-term lubrication). Tighten any loose fasteners. If parts are broken, they need replacement.
5. Inspect the Wiper Blades:
* Location: These are the rubber pieces at the end of the wiper arms.
* Testing: Check for wear and tear. Cracked, worn, or stiff blades will not wipe effectively. Replace worn blades. This is often the simplest and cheapest fix.
6. Examine the Wiper Arm Connections:
* Location: The wiper arms attach to the wiper transmission.
* Testing: Ensure the arms are securely attached. Sometimes they can loosen and slip, causing poor wiping. Tighten if necessary.
7. Consider the Park Position:
* Sometimes the wipers may not park correctly, making it hard to start the next cycle. This typically requires adjustment or lubrication of the wiper linkage.
Troubleshooting Tips:
* Start simple: Begin with the easiest checks (fuses and wiper blades) before moving to more complex repairs (motor replacement).
* Owner's Manual: Consult your 1993 Plymouth Acclaim's owner's manual for diagrams and specific instructions.
* Professional Help: If you are uncomfortable working on your car's electrical system or mechanical components, take it to a qualified mechanic.
Replacing parts might require some mechanical aptitude. You'll likely need basic tools like screwdrivers and possibly pliers. Remember to disconnect the battery's negative terminal before working on any electrical components to avoid short circuits.
