What fuse is temperature gauge on Oldsmobile alero?

The Oldsmobile Alero doesn't have a dedicated fuse specifically for the temperature gauge. The gauge is part of the instrument cluster's electrical system. If your temperature gauge isn't working, the problem is more likely to be within the instrument cluster itself, a faulty temperature sensor, or a problem with the wiring connecting them, rather than a blown fuse.

To troubleshoot:

1. Check the instrument cluster fuses: Look in your owner's manual for the fuse box diagrams. The fuses related to the instrument panel or the entire gauge cluster are the ones you should check first. They are usually labeled as "Instrument Panel" or similar.

2. Check the coolant temperature sensor: This sensor is located in the engine block and sends the temperature reading to the gauge. A faulty sensor will prevent an accurate reading or cause the gauge to malfunction. A mechanic or online resources specific to your Alero's year and engine can help you locate it.

3. Inspect the wiring: Look for any damaged or loose wiring connections related to the instrument cluster or the temperature sensor.

If you've checked these and still have issues, it's likely a problem with the instrument cluster itself or a more complex electrical fault requiring professional diagnosis.
