If the temperature gauge in your 2004 Grand Marquis isn't moving, it could be due to a faulty thermostat, which may be stuck open, preventing the engine from reaching the proper operating temperature. Another possibility is a malfunctioning temperature sensor or gauge itself. Additionally, check for issues like low coolant levels or a blown fuse affecting the gauge. It's best to have a professional diagnose the issue to ensure accurate repairs.
