When the heated seat control switch is pressed with the ignition switch in RUN or START, a ground signal is sent to the heated seat module on circuit 1255 (WH/RD) to command the system ON or OFF in LOW heat mode.
Possible Causes
A driver heated seat that does not operate in LOW can be caused by:
- faulty wiring, terminals or connectors.
- a faulty heated seat switch.
- a faulty heated seat module.
