B1419 — Passenger Power Window Motor Circuit Open

body electrical

Is it safe to drive?

Short-term driving is OK Usually safe to drive — body codes rarely affect drivability. Exceptions: exterior lighting and wipers in bad weather, and central locking faults that can leave the car unsecured.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm B1419 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many B0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the body electrical system for damage, corrosion, chafing or poor contact.
Subsystem check Do a continuity test end-to-end on the passenger power window motor circuit and wiggle the harness while measuring — intermittent opens show up as fluctuating readings.
Subsystem check Operate the affected function while watching its switch and motor PIDs in live data.
Subsystem check Inspect connectors and wiring at flex points (door jambs, tailgate hinges) — wires break there first.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm B1419 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for B1419 (parts and labor, USD, independent shop rates): Replace the switch or actuator: $120–$450; BCM repair or replacement: $300–$900; Repair wiring or connectors: $80–$250. Overall, fixing B1419 usually costs between $80 and $900. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What does OBD2 code B1419 mean?

Passenger Power Window Motor Circuit Open (B1419): a body electrical fault affecting the body electrical system. The car is usually drivable while you plan the repair. Most often caused by blown fuse or failed relay, faulty switch, motor or actuator of the affected system, corroded or loose connectors.

Is it safe to drive with B1419?

Usually safe to drive — body codes rarely affect drivability. Exceptions: exterior lighting and wipers in bad weather, and central locking faults that can leave the car unsecured.

What is the most common cause of B1419?

The most common causes are: blown fuse or failed relay, faulty switch, motor or actuator of the affected system, corroded or loose connectors.

How much does it cost to fix B1419?

Replace the switch or actuator — $120–$450; BCM repair or replacement — $300–$900; Repair wiring or connectors — $80–$250. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What are the symptoms of B1419?

Drivers most often notice: no impact on engine operation in most cases, the affected function (locks, windows, lighting, wipers) works intermittently or not at all, warning light on the dashboard.

When your vehicle's onboard computer detects that the electrical circuit feeding the passenger side power window motor cannot complete its path, it logs trouble code B1419. This code falls squarely in the body electronics category, meaning it relates to comfort and convenience features rather than engine management or safety systems. The term "circuit open" tells you exactly what went wrong: somewhere along the wire running to or from that motor, the electrical path is interrupted. Current simply cannot flow where the module expects it to.

The control module responsible for window operation constantly watches voltage and resistance readings at key points in the circuit. When those readings stray outside acceptable ranges—typically across multiple ignition cycles—the module flags the condition and sets B1419. Along with the code itself, the computer saves a freeze frame snapshot capturing engine RPM, load, coolant temperature, and vehicle speed the instant the fault occurred. That snapshot proves invaluable during diagnosis, since it shows you exactly what conditions triggered the problem.

Understanding the underlying mechanism matters for another reason: B1419 rarely announces a dead motor right away. An intermittent open—say, a wire that breaks only when you close the door—triggers the same code as a completely severed harness. This distinction shapes how you approach the troubleshooting process, which we'll walk through next.

Common Symptoms

The passenger window fails to respond when you press the switch, or operates sluggishly and stops partway
No other drivetrain functions are affected—acceleration, braking, and steering remain normal
Interior lighting, central locking, or other body electronics may behave erratically if the fault involves shared wiring or the body control module
The check-engine light typically stays off; instead, you may see a dedicated body system warning lamp illuminate
The problem can be intermittent, with the window working after a vehicle restart only to fail again minutes later
In some cases, fuses related to the circuit appear intact but carry no current

Typical Causes

A blown fuse dedicated to the window circuit—the most common and cheapest culprit
Corrosion, moisture intrusion, or debris trapped inside the electrical connector at the passenger door harness
A passenger power window motor that has developed an internal open circuit and no longer functions
Broken or chafed wiring within the door boot, where wires flex every time the door opens and closes
A faulty window switch on the passenger door panel or master switch assembly
Body control module software glitches or hardware failure affecting multiple body functions
Loose ground connections associated with the door harness

How to Diagnose

Plug in a quality OBD2 scanner, retrieve code B1419, and record the freeze frame data before clearing anything. This frame tells you engine conditions when the fault appeared.
Check for any accompanying trouble codes in the B0xxx family. Codes appearing alongside B1419 often point to the real root cause—a shared power supply problem, for instance.
Visually trace the passenger window circuit from the switch to the motor. Look for damaged insulation, melted wire, green corrosion crust, or pins that have backed out of their housings.
Perform a continuity test on each wire segment, paying special attention to flex points near door hinges. Gently wiggle the harness during testing to expose intermittent opens.
Test the window switch for proper resistance values when actuated, then verify that the motor receives battery voltage when the switch is engaged.
If no wiring faults surface, swap the passenger window motor with a known-good unit as a final verification step before condemning the body control module.

Repair Options with Costs

Switch or actuator replacement typically runs $120–$450, depending on whether you need only the passenger switch or the entire motor assembly.

Wiring or connector repair generally costs $80–$250. Most of this work involves splicing a short section of harness, cleaning corrosion from connector pins, or applying dielectric grease to prevent future moisture intrusion.

BCM diagnosis and repair or replacement sits at the higher end: $300–$900. Shops usually attempt software updates and relay replacement before recommending a full BCM swap, since the module often controls dozens of functions.

Total repair costs for B1419 range from as little as $80 for a simple fuse or connector cleanup to $900 for full body control module replacement. The most expensive fix is rarely the starting point—always confirm the exact failure point before spending big money.

Can You Drive with B1419?

B1419 presents minimal risk to safe vehicle operation. Engine performance, braking, and steering remain completely unaffected. The main concerns are convenience-related: you lose passenger window operation, and if the fault stems from shared BCM circuitry, you might also experience intermittent lighting, wiper, or lock behavior. Address exterior lighting and wiper issues promptly if they appear, since visibility and security matter regardless of drivability classification.

Severity: Short — safe to drive, but address the underlying issue before it leaves you stranded or compromises security.
