* Under the hood in the fuse box: This is the most common location. The fuse box is usually located either near the battery or on the passenger side fender well. Check the fuse box diagram (usually on the inside of the lid) for the blower motor relay. It will often be labelled clearly.
* Inside the passenger compartment fuse box: Some Aleros might have it located inside the cabin, often under the dashboard on the driver's or passenger's side. Again, check the fuse box diagram.
* Integrated into the HVAC control module: In some less common cases, the relay might be integrated directly into the climate control module itself, making it impossible to replace individually. This is less likely but possible.
To find it, I strongly recommend:
1. Consult your owner's manual: This is your best resource. It will have a diagram of the fuse box(es) showing the location of the blower motor relay.
2. Check online resources: Search for "2001 Oldsmobile Alero blower motor relay location" on Google Images. Pictures from other Alero owners might show its position. Be aware that different trims might have slight variations.
3. Use a wiring diagram: A wiring diagram for your specific year and model Alero will show you exactly where the relay is and how it's connected. You might find a free diagram online (but be cautious about their accuracy) or buy one from an auto parts store.
Important Note: Before attempting any work, always disconnect the negative terminal of your car battery to prevent electrical shocks. If you're unsure about working with electrical components, take your car to a qualified mechanic.
