Causes

Damaged or faulty visor assembly (switch, lamp, motor or position sensor)
Loose, corroded or disconnected connector at the visor
Broken or chafed wiring in harness between visor and overhead module
Blown fuse or poor fuse/relay connection for interior lamps/visors
Water ingress or contamination in headliner area affecting connector/sensor
Faulty body control module / overhead module or software anomaly

Symptoms

Illuminated vanity mirror lamp does not turn on or is intermittent
Visor position detection (if equipped) not working or reporting incorrectly
Visor motorized movement does not operate (if equipped)
Interior warning or message related to visor/trim may appear
Related DTC remains stored and may reappear after clearing

What to check

Read all stored codes and freeze frame data with an OEM-capable scanner; note any related B or U codes
Visually inspect the visor assembly for physical damage, water stains or corrosion
Inspect and reseat the electrical connector at the visor and overhead module
Check related fuses and relays for continuity and proper seating
Perform a wiggle test of the wiring harness while observing connector and system behavior
Check for signs of previous repair or pinched wiring where harness passes under trim

Signal parameters

Supply voltage at visor connector: approx. 11–14 V with ignition/accessory ON (if circuit powered)
Ground continuity to chassis:
Switch continuity: closed/near 0 Ω when engaged, open/infinite when released (where applicable)
Lamp load: expected low-resistance path when lamp is intact (check bulb/LED and wiring)
CAN/LIN network: overhead module should be present on bus and report normally via scan tool (no bus communication faults)

Diagnostic algorithm

Use a dealer-level or capable scan tool to read DTC B108E and any related codes; record freeze frame and clear codes to see if they return.
Visually inspect the visor and surrounding headliner for damage, water ingress, or obvious wiring issues; repair any physical damage found.
With battery/ignition state as required, disconnect the visor connector, inspect terminals for corrosion or bent pins, then reconnect firmly.
Check relevant fuses and relays for continuity; replace any faulty items.
Backprobe the visor connector: verify supply voltage, ground continuity and switch/position sensor signals while operating the visor or opening the vanity mirror.
If wiring appears damaged or intermittent during wiggle testing, trace and repair the harness; repair splices with solder/heat-shrink or OEM-style terminals.
If wiring and connector test good, check for communication with the overhead/body control module via scan tool; review module inputs for the visor circuit.
If module inputs indicate a fault with a good harness and component, consider reflashing module software if an update/TSB exists or replace the overhead/module per OEM diagnostic guidance.
Replace the visor assembly only after confirming the electrical supply, ground and control signals are correct and the component itself fails bench/functional testing.
Clear codes and re-test vehicle operation; verify code does not return under normal use and perform a short road or usage test as required.

Likely causes

Corroded or loose connector at visor (most common)
Failed vanity lamp or switch inside visor
Wiring harness damage where it passes through A-pillar/headliner
Blown or poor fuse/connection supplying visor circuit
Faulty overhead/body control module (least common)

Fault status

⚠️ Status

Visor circuit fault detected — inspect visor assembly, connector and wiring; verify power, ground and control signals. Module communication or component failure possible.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5 - 1.5 hours
