Here's why:
* Model and Engine variations: BMW models often have different component placements, even within the same year and series. The engine code (e.g., M42, M44) is essential for pinpointing the location.
* Relay Placement: The auxiliary fan relay can be located in different places, such as the engine compartment fuse box, the passenger compartment fuse box, or a separate relay box.
To find the auxiliary fan relay, follow these steps:
1. Identify your engine code: This is usually found on a plate near the engine, or on the vehicle's registration papers.
2. Consult your vehicle's repair manual: The manual will have a diagram showing the locations of all relays and fuses.
3. Look for the relay diagram: Some relays might be labeled, while others may require you to test them with a multimeter to identify them.
Alternative methods:
* Use a BMW service manual: A service manual specific to your model and year will have detailed information on component locations.
* Consult an online forum: Forums dedicated to BMWs often have threads discussing relay locations.
Remember:
* Working on electrical components can be dangerous. Always disconnect the battery before working on any electrical systems.
* If you are unsure about the procedure, consult a qualified mechanic.
By following these steps, you can find the auxiliary fan relay on your 1996 BMW 318i convertible.
