Lumbar Motors
WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
The lumbar support system consists of two lumbar motors, horizontal and vertical, that operate independently of each other. The horizontal motor moves the lumbar support forward or rearward, and the vertical motor moves the lumbar support up or down. Each motor contains an electronic circuit breaker (PTC), that opens the circuit in the event of a circuit overload and will reset only after the voltage has been removed from the circuit.
