Troubleshooting the Audiovox SCO1 Single Seat Warmer

Troubleshooting the Audiovox SCO1 Single Seat Warmer

If system does not heat up or no indication of power:

• Check fuse in seat heater harness and vehicle.
• Temperature of seat may be above the preset thermostat temperature and will not allow it to come on. (ie: sun shining on seat)
• If the light on the heated seat switch does not come on, it could be that the switch bulb is burnt out (replace switch) or that there is no power to the switch.
• Ensure all connectors are properly connected and the ground wire is properly grounded. Refer to Figure 9 for wiring diagram.
• Using an ohm meter, test only the heating elements (switch not included) from the under seat wire connector. If no resistance is found, then an open condition exists.
• Check internal wire connectors for an open circuit. If a heating element has an open, install a new heating element.
• If the heating elements and seat harness tests OK, then a power supply problem exists.
• Using a digital volt meter, start at the source and trace back through all the connectors and switch to determine where the power loss is occurring. Repair as necessary.
• If the seat heater fuse continues to blow, then a short or bad ground condition exists in the power circuit.
• If the vehicle fuse, which has the heated seat T-tap connected to it, continues to blow then the tap will need to be moved to another vehicle circuit.
