* Incorrect Fuse Replacement: You might have installed the wrong amperage fuse. This is a common mistake and can blow the new fuse immediately or damage other components. Double-check the fuse rating in your owner's manual or a reliable online source for your specific LeBaron model.
* Fuse Box Issues: The fuse box itself might be faulty. A corroded connection, loose wire, or a damaged socket could be interrupting the circuit even with a good fuse. Inspect the fuse box carefully for any signs of corrosion, burnt contacts, or loose wires.
* Underlying Electrical Problem: The fuse is a protective device. If a fuse keeps blowing, it means there's a short circuit or a significant problem in the wiring or a component in the wiper or turn signal system. This could be a shorted wire, a faulty wiper motor, a bad turn signal switch, or a problem with the flasher relay.
* Damaged Wiring: While changing fuses, you might have accidentally damaged a wire or connector in the fuse box area. Carefully inspect all wiring near the fuse box.
* Relay Failure: The turn signals and wipers likely rely on relays. A bad relay can cause these systems to fail despite good fuses.
Troubleshooting Steps:
1. Verify Fuse Ratings: Absolutely confirm you have the correct amperage fuses installed. If you've already checked, do it again!
2. Inspect the Fuse Box: Thoroughly examine the fuse box for corrosion, burnt contacts, or loose wires. Pay close attention to the connections for the wipers and turn signals.
3. Test the Fuses (Again): Use a multimeter to test the fuses, even if they look good visually. A blown fuse might not always be obvious.
4. Check the Wiring: Trace the wiring from the fuse box to the wiper motor and turn signal switch. Look for any breaks, chafing, or corrosion.
5. Test the Wiper Motor and Turn Signal Switch: If possible, test these components with a multimeter to see if they're receiving power and functioning correctly. This often requires more advanced electrical knowledge or a professional.
6. Check the Flasher Relay: Locate the flasher relay (it's usually a small square component) and replace it as a test.
Important Note: Working on car electrical systems can be dangerous. If you're not comfortable performing these checks, take your LeBaron to a qualified mechanic. Attempting repairs without proper knowledge could lead to further damage or injury.
