1. Identify the Problem:
* Wipers Not Working at All: This points to a problem with the power source (fuse, switch, motor).
* Wipers Working Intermittently: Could be a faulty wiper motor, worn wiper switch, or a wiring issue.
* Wipers Moving Slowly or Erratically: Likely worn motor brushes or a problem with the motor itself.
* Wipers Sticking or Skipping: This usually indicates worn wiper blades, a dirty windshield, or a problem with the wiper arms/pivots.
2. Troubleshooting Steps:
* Check the Fuse: Locate the fuse box (usually under the dash or in the engine compartment) and check the fuse designated for the wipers. Replace if blown. Consult your owner's manual for the correct fuse rating and location.
* Inspect the Wiper Switch: Try different wiper settings (intermittent, low, high). A malfunctioning switch is a common culprit. Testing the switch requires some electrical knowledge or access to a multimeter.
* Examine the Wiper Motor: This is typically located under the hood, near the base of the windshield. Listen for any unusual noises (grinding, clicking) when you turn the wipers on. A noisy motor is usually a sign it needs replacement or repair (often not practical for DIY).
* Check the Wiper Linkage: Inspect the linkage connecting the motor to the wiper arms for any broken or loose components. This often involves removing the cowl (plastic cover) under the windshield.
* Inspect Wiper Blades and Arms: Replace worn or damaged wiper blades. Check the wiper arms for any stiffness or damage. Clean the windshield thoroughly. If the arms are stiff, try lubricating the pivot points with a silicone-based lubricant (NOT WD-40).
3. Repair or Replacement:
* Wiper Blades: These are the easiest to replace. Just unhook the old blades and snap on the new ones. Get blades that are the correct size for your 1988 Plymouth Reliant.
* Wiper Motor: Replacing the wiper motor requires mechanical skills and access to a replacement motor. This is a more involved repair.
* Wiper Switch: Replacing the wiper switch requires some electrical knowledge and the removal of the steering column cover (often a complex procedure).
* Wiring: If you suspect a wiring problem, you'll need to trace the wiring harness, looking for breaks, corrosion, or loose connections. This can be challenging without a wiring diagram.
4. Tools You Might Need:
* Screwdrivers (Phillips and flathead)
* Pliers
* Fuse puller
* Multimeter (optional, for electrical testing)
* New wiper blades
* Silicone-based lubricant
* Replacement parts (fuse, motor, switch, etc.)
* Owner's manual
Important Considerations:
* Safety First: Always disconnect the battery's negative terminal before working on any electrical components.
* Owner's Manual: Your owner's manual is an invaluable resource. Consult it for specific information on your vehicle's wiper system.
* DIY vs. Professional: If you're not comfortable with electrical or mechanical repairs, it's best to take your car to a qualified mechanic. Repairing the motor or switch can be difficult.
This guide provides a general overview. The exact steps may vary slightly depending on your specific Reliant model. Always refer to your owner's manual for detailed instructions and diagrams. Good luck!
