* Wipers Motor Failure: The most common culprit is a faulty wiper motor itself. It might be seized, burnt out, or have internal electrical problems preventing it from functioning.
* Wipers Linkage Problems: The linkage connecting the motor to the wiper arms can be damaged, broken, or seized. This could be due to age, rust, or wear and tear. A bent arm or a disconnected component will prevent movement.
* Electrical Issues:
* Fuse: A blown fuse in the wiper circuit will prevent power from reaching the motor. Check your fuse box for a blown fuse related to the wipers.
* Wiring: Worn, corroded, or broken wires in the wiper circuit can interrupt power. This often happens near the motor or where the wiring harness is flexed.
* Switch: The wiper switch itself might be malfunctioning. It could be internally broken or have a bad connection.
* Relay: Some wiper systems use a relay to control the motor. A failed relay can also be the cause.
* Park Mechanism: The mechanism that parks the wipers in the up position might be jammed or broken.
* Vacuum System (Less Likely): While less common in later models, some older vehicles *might* use a vacuum system for wipers. A leak in the vacuum line could cause this issue. However, this is unlikely in a '97 Camaro.
Troubleshooting Steps:
1. Check the Fuse: This is the easiest first step. Locate the wiper motor fuse in your fuse box (consult your owner's manual) and check its condition.
2. Listen for Clicking: Turn on the wipers. Do you hear any clicking from the wiper motor area? A clicking sound might indicate a power issue (fuse, relay, switch) but a weak motor.
3. Inspect the Linkage: Visually inspect the wiper linkage for any broken or bent parts. Try manually moving the wiper arms (carefully!) to see if they are free moving or stuck.
4. Check for Power at the Motor: If you have some electrical experience, use a multimeter to check for power at the motor connector. This requires caution and understanding of electrical safety.
5. Test the Wiper Switch: If possible, test the switch by replacing it with a known good one (borrowed or purchased).
If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic. Diagnosing this problem might require specialized tools and experience.
