* Turn Signal Flasher Module: This is the most likely candidate for what you're looking for. It's a small electronic module, often integrated into the fuse box itself and not a separate replaceable relay in the traditional sense. It controls the flashing rate. You'll need to consult your owner's manual or a wiring diagram to identify it within the fuse box.
* Other Relays: Other relays *might* be involved in the power supply to the turn signals but rarely fail independently of the flasher module.
To find it:
1. Consult your owner's manual: This is the best place to start. It should have a diagram of the fuse box showing the location of the flasher module or any relevant relays.
2. Check online resources: Search for a "2002 Chevy Malibu fuse box diagram" online. Many websites and forums have these diagrams. Look for a component labeled "turn signal flasher," "flasher module," or a similar designation.
3. Visual inspection: With the fuse box cover removed, carefully examine the components. The flasher module will be a small, rectangular component, possibly with some markings. Be careful not to touch any electrical components while the car's battery is connected.
4. If you're unsure, take it to a mechanic: This is the safest option if you're not comfortable working on your car's electrical system.
Keep in mind that a malfunctioning turn signal system can be caused by many things, not just a bad flasher module. Bulbs, wiring, and the turn signal switch itself are also potential culprits.
