Causes

Blown fuse or faulty relay for seat heating circuit
Open or shorted wiring between seat heater element and control module
Faulty left front seat heater element (broken/shorted heating wire)
Defective seat heater switch or control unit
Poor connector contact, corrosion or water ingress in the seat or harness
Control module internal fault or software error

Symptoms

Left front seat heater does not warm or warms intermittently
Seat heater indicator lamp off or flashing when selected
Heater stuck on or uncontrollable heat level (rare)
Diagnostic warning or stored fault message related to seat heating
Possible mild burning or electrical smell (if short or overheating)

What to check

Scan vehicle and confirm B1032 and any related codes; note freeze-frame/live data
Inspect seat heater fuse(s) and related relays; verify fuse continuity
Visually inspect seat connector(s) and wiring harness for damage, corrosion or water
Operate seat heater controls and observe indicator lamps and scan-tool live data
Measure voltage at the seat heater connector with heater ON and OFF
Measure resistance of the heater element (seat disconnected) and compare to expected range

Signal parameters

Supply voltage to seat heater: ~12 V when heater is switched ON
Heater element resistance: typically low single-digit ohms (varies by design; expected to be low, not infinite)
Control signal: on/off or PWM from seat control module (scan tool may show commanded state)
Connector pin continuity to control module: near zero ohms (short length) or consistent with wiring length

Diagnostic algorithm

Connect an appropriate diagnostic scan tool; read and record B1032 and any other stored codes and live data.
Confirm operation of the seat heater via controls and observe scan-tool outputs for the left front seat circuit (command/state).
Inspect fuses/relays for the seat heater circuits; replace any blown fuses and re-test.
Visually inspect connectors at the seat, under-dash harness, and B-pillar routing for damage, corrosion, or water ingress; repair as necessary.
With seat disconnected from module, measure resistance of the left front heater element (cushion and/or backrest). An open (infinite) reading indicates a broken element; a very low or near-zero may indicate a short.
With connector connected, measure voltage at the seat heater supply pin with heater commanded ON. No supply → supply/wiring/fuse/relay issue. Constant supply when OFF → control module/relay stuck.
Check continuity between the seat heater connector and the control module connector to identify open or high-resistance wiring.
If wiring and connectors check OK but element fails or shows abnormal resistance, replace the faulty heater mat/seat cushion module.
If heater element and wiring are good, test/replace the seat heater switch or seat control module per manufacturer procedures.
After repairs, clear codes and perform a full functional test; road/test or cycle functions to ensure code does not return.

Likely causes

Open or damaged heater element in the seat cushion/backrest
Faulty wiring or connector to the left front seat (chafed harness, disconnected plug)
Failed seat heater switch or seat control module
Blown fuse or intermittent supply/ground

Fault status

⚠️ Status

Left front seat heater circuit fault detected (B1032). Possible open/short, failed heater element, faulty switch or module, or wiring/connectivity issue.
