Causes

  • Open or shorted seat heating element (right front)
  • Damaged or corroded connector or wiring harness to the seat heater
  • Faulty seat heater control module or seat control unit
  • Blown fuse or faulty relay in the seat heating supply circuit
  • Intermittent connector contact due to movement or broken wires in the seat loom
  • High resistance due to partial break or damaged heating element mat

Symptoms

  • Right-front seat heater does not heat or heats intermittently
  • Seat heater indicator light may not illuminate or flashes
  • Uneven heating across the seat cushion or backrest
  • DTC B1036 stored in vehicle diagnostic memory
  • Possible reduced functionality on seat heating control (no change in heat levels)

What to check

  • Retrieve freeze-frame data and confirm B1036 is stored and current/past
  • Check for other related DTCs (seat modules, body control module)
  • Visually inspect right front seat base for damaged wiring, connector corrosion, or pin damage
  • Check relevant fuses and relays in the interior fuse/relay panel
  • Operate seat heater while monitoring connector and wiring for intermittent faults (careful with moving parts)
  • Perform a resistance (ohms) check across the heating element terminals with seat disconnected from vehicle power

Signal parameters

  • Nominal supply voltage to seat heater: approx. 11–14 V with ignition/seat heater ON
  • Heating element resistance (typical range): ~0.5–10 Ω depending on pad design — consult vehicle spec
  • Current draw when full heat: up to ~5–15 A (varies by model and pad)
  • Control signal may be PWM from seat module: 0–100% duty cycle
  • Expected continuity: present (low ohms); open circuit indicates broken element

Diagnostic algorithm

  1. Connect a diagnostic scanner and read/record B1036 and any related codes; note freeze-frame and status (current/historic).
  2. Visually inspect the right front seat: connectors at seat base, wiring along seat rails, and heating element harness for damage, chafe, or corrosion.
  3. Verify fuses and relays for seat heating circuit; replace if blown and retest. If fuse blows immediately, suspect short in harness or element.
  4. With ignition off, disconnect the seat module connector and measure resistance across the heating element terminals (refer to vehicle-specific resistance spec). An open circuit (infinite ohms) indicates the heater mat is broken; very high resistance indicates partial break.
  5. With ignition on and heater control activated, backprobe the power feed to the seat heater and confirm battery voltage present when heater is commanded on. Also backprobe module output for expected PWM signal if applicable.
  6. Wiggle-test wiring and connectors while observing resistance/voltage or scanner live data to identify intermittent faults caused by seat movement.
  7. If wiring and power are good but element resistance is out of spec, replace the right front seat heating element/pad or complete seat cushion assembly per manufacturer instructions.
  8. If element and wiring are good but no control signal, test/replace the seat control module or body control module outputs after confirming driver inputs and communications.
  9. Clear codes and perform functional verification: confirm heater operation across settings and re-scan for recurrence of B1036.

Likely causes

  • Broken heater element trace in the right front seat pad
  • Corroded or loose multi-pin connector at seat base
  • High-resistance splice or chafe in harness caused by seat movement
  • Faulty passenger seat control module or body control module output transistor
  • Blown or undersized fuse for the seat heater circuit

Fault status

⚠️ Status
Stored fault: B1036 — Right front seat heating element/circuit fault detected. Possible open, short, high resistance or control circuit failure; check element, wiring, connectors, fuses, and seat control module.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.0-2.5 hours
