1. Wipers Not Working at All:
* Check the fuses: Consult your owner's manual to locate the fuse(s) for the wipers. Replace any blown fuses.
* Check the wiper motor: This is usually located under the hood, often near the base of the windshield. You might need to remove some plastic covers to access it. Listen for a clicking sound when you turn the wipers on – a clicking sound might indicate a bad motor. A multimeter can test if the motor is receiving power.
* Check the wiper switch: The switch itself could be faulty. This is a more involved repair, potentially requiring disassembly of the steering column.
* Check the wiring: Inspect the wiring harness leading to the motor for any breaks, corrosion, or loose connections. This often involves tracing the wires from the switch to the motor.
2. Intermittent Wipers Not Working Properly:
* Check the intermittent wiper control: This is often a part of the wiper switch itself. It's a more complex component that's difficult to repair; often, replacement is the solution.
* Check the wiring again: Focus on the wiring related to the intermittent function.
3. Wipers Working but Wiping Poorly (Streaking, Skipping):
* Replace the wiper blades: This is the most common cause of poor wiping. Ensure you get blades of the correct size for your 1990 Dodge Spirit.
* Clean the windshield: Dirt, bugs, and grime can interfere with proper wiping. Use a glass cleaner and a microfiber cloth.
* Check the wiper arms: Make sure the wiper arms are securely attached to the wiper motor. They might be loose or have worn pivot points. Tighten any loose connections. If the arms are bent, they may need replacing.
* Check the wiper linkage: This is the mechanical connection between the motor and the wiper arms. Look for any broken or worn parts. Repair or replacement might be needed.
4. Wipers Stuck:
* Try manually moving the wiper arms: If they're frozen, try carefully freeing them up. Use de-icer if necessary.
* Check for obstructions: Something might be preventing the arms from moving.
Important Notes:
* Safety First: Disconnect the battery's negative terminal before working on any electrical components.
* Owner's Manual: Your owner's manual will provide diagrams and specifications specific to your 1990 Dodge Spirit.
* Repair Manual: A repair manual (Haynes or Chilton) can provide detailed instructions and diagrams for more involved repairs.
* Professional Help: If you are not comfortable working on your car's electrical system or mechanical components, take it to a qualified mechanic. Some repairs, like replacing the wiper motor or switch, can be quite complex.
Remember to always consult your owner's manual for specific information about your vehicle's wiper system. Starting with the simplest solutions (new wiper blades, checking fuses) is always the best approach.
