Gauge Always Indicates Cold (Van)
- Disconnect temperature sending unit connector. Turn ignition on. Connect fused jumper wire between engine coolant temperature sensor connector terminal "A" (Dark Green wire) and ground. If gauge remains at cold, go to next step. If gauge moves toward hot, replace sending unit.
- Remove jumper wire. Connect self-powered test light between instrument cluster connector terminal B9 (Dark Green wire) and sending unit terminal "A" (Dark Green wire). If test light comes on, replace instrument cluster. If test light does not come on, repair open circuit in Dark Green wire.
