What Safety Precautions Should Be Taken When Servicing the Seat Heater Switch on Mercury Mariner?

Wear safety glasses when servicing the heated seat switch to avoid being hurt by airbag deployment. Always never probe airbag connectors. Start with power off on SRS. Make sure that the SRS is fully functioning and then give the vehicle back. Disassemble the needed parts to reach the switch that opens the heated seat and repeats the process with installing and reenergizing the SRS.
