E72C

What the Code Means

E72C falls under the electrical category and carries moderate severity. The code is similar to E72B — it also points to a window fault, but it may refer to a different window regulator or to the same problem logged a second time.

The FRM (footwell module) controls the window regulators and sets the fault when their operation deviates from expected. Typical reasons FRM flags a fault: a seized window motor, overcurrent in the circuit, or a faulty window position sensor.

Symptoms

• The window doesn't work (won't go down or up);
• intermittent window regulator operation — the function comes and goes;
• the anti-trap warning triggers with no real obstruction.

Diagnosis and Repair

1. Inspect the window mechanism — check glass travel and the regulator for binding that can stall the motor and cause overcurrent.
2. Check the wiring harness for damage — chafed or broken wires in the door boot cause intermittent operation.
3. Run a window initialization — afterward the module relearns the end positions and the anti-trap function.
4. Replace the FRM if several windows fail at once — that points to the module itself, not a single circuit.

Secondary Problems

• The window can fail completely, which will require replacing the window regulator. Don't put off the repair: running with a faulty mechanism speeds up its final failure.
