Outside weather temperature gauge malfunctions in your 2000 Cadillac DTS?

If the outside temperature gauge in your 2000 Cadillac DTS is malfunctioning, it could be due to a faulty sensor, a wiring issue, or a problem with the gauge itself. Start by checking the sensor located near the front of the vehicle for any damage or disconnection. If the sensor appears intact, inspect the wiring for any signs of wear or corrosion. If these components are fine, the issue may lie within the vehicle’s instrument cluster, and a professional diagnosis may be necessary.
