1. Fuses: Check the fuse box (usually under the hood or inside the car, often near the steering column) for blown fuses related to the power windows. Your owner's manual will show you which fuses control the windows.
2. Window Switch: The problem could be with the master window switch (usually on the driver's side door). Try all the other window switches to see if they work. If only the driver's side windows don't work, it's likely the master switch. These switches are prone to wear and tear.
3. Window Motor: If a specific window doesn't work, the motor itself might be faulty. This requires more investigation; you'll need to access the motor to check it for operation and/or continuity.
4. Window Regulator: The regulator is the mechanical system that moves the window. It can get worn, broken, or jammed, preventing the window from moving, even if the motor works. This usually requires removing the door panel to inspect.
5. Wiring: Damaged, corroded, or disconnected wiring between the switch, motor, and regulator is a common culprit. Inspect the wiring harness for any visible damage, especially at the connection points.
6. Relay: Some Chrysler models use relays for the power windows. A faulty relay can prevent the circuit from working. Finding the correct relay requires consulting your owner's manual.
7. Power Supply: Check the car's battery voltage. A low voltage can affect power-hungry components like the power windows.
Troubleshooting Steps:
1. Start with the simplest: Check the fuses first. It's the easiest and cheapest fix.
2. Isolate the problem: Does it affect all windows, or just one? This helps narrow down the possible causes.
3. Test the switches: Try all the switches to see if the problem is with a specific switch or a more general electrical issue.
4. Visual inspection: Look for any obvious signs of damage to the wiring or components.
5. Consult a wiring diagram: A wiring diagram for your specific LeBaron year and model will be invaluable in tracing the circuits. These are often available online.
If you're not comfortable working on car electrical systems, it's best to take your LeBaron to a qualified mechanic. Incorrectly diagnosing and attempting to repair electrical issues can cause further damage.
