Why is the engine cooling fan on your 04 buick not working?

The engine cooling fan on your 2004 Buick may not be working due to a few common issues, such as a blown fuse, a faulty relay, or a malfunctioning temperature sensor that fails to signal the fan to engage. Additionally, the fan motor itself could be defective or there may be wiring issues preventing proper electrical flow. It's advisable to check these components to diagnose and resolve the problem effectively.
