Causes
- Physical binding or contamination inside the left rear window switch (stuck contacts or debris)
- Short to ground on the left rear window DOWN circuit
- Short to battery or stuck high on the left rear window UP circuit (seen as conflicting inputs)
- Corroded/damaged connector or wiring harness to the switch or motor
- Faulty left rear window motor or regulator causing abnormal current/feedback
- Water intrusion into the door or switch assembly
Symptoms
- Left rear window will not respond to commands or remains down
- Window moves down continuously or will not move up
- Switch feels stuck, loose, or unresponsive when pressed
- Blown fuse or repeated fuse issues on window circuit (in some cases)
- Other window switches or central controls may be unresponsive if BCM detects fault
What to check
- Visually inspect left rear door switch and bezel for signs of foreign material or water intrusion
- Check door harness and connector at door jamb for chafing, corrosion, or pin damage
- Scan vehicle with a diagnostic tool for B2205 and any related body/communication codes
- Check relevant fuses and relays for the power windows circuit
- Operate the switch while observing connector pins (backprobe) for proper voltage changes
- Listen for motor noise when operating the switch and observe window movement
Signal parameters
- Switch supply voltage (key on): approx. battery voltage ~12–14 V on the common feed
- Switch DOWN output: near 0 V (ground) or battery voltage depending on system — expected to change state when pressed
- Switch UP output: opposite polarity to DOWN on many systems; should switch between battery and ground when operated
- Motor stall current: typically in the range of several amps (2–30 A depending on motor); a sustained high current indicates a mechanical bind or short
- Continuity: low resistance between switch terminals when actuated (near 0–a few ohms for closed contacts)
Diagnostic algorithm
- Read and record fault codes with a compatible scan tool; clear codes and reattempt to replicate.
- Perform a visual inspection of the left rear door switch, switch bezel, and wiring for contamination, water, or visible damage.
- Check fuses and relays for the window circuit; replace if blown and note if reoccurs.
- With the ignition ON, backprobe the switch connector. Operate the switch and verify the DOWN and UP signal voltages change as expected relative to battery and ground.
- If the switch appears to be stuck electrically, disconnect the switch connector. If the fault clears or behavior changes, suspect the switch. If the window still behaves as if DOWN-stuck with the switch disconnected, check wiring to the BCM for a short to ground.
- Inspect the door harness through the door jamb for broken wires — flex the door while monitoring the circuit to replicate any intermittent short.
- If switch signals appear correct, check the motor/regulator: support the window, command operation and check for excessive current with a clamp meter. High stall current suggests mechanical bind or failing motor.
- Remove and bench-test the switch if accessible: measure continuity across contacts while actuating. Clean or replace the switch as necessary.
- Inspect and clean connectors with contact cleaner and apply dielectric grease after repair. Replace damaged wiring or connectors.
- If wiring and switch check good, consult BCM/window module diagnostics — test outputs at module and verify communication; if module output is faulted, consider module repair or replacement per manufacturer procedure.
- After repairs, clear codes, cycle the window several times, and confirm normal operation and that the code does not return.
Likely causes
- Switch contacts welded or seized by dirt/oxide/water
- Pinched/chafed wiring in door harness causing a constant ground on the DOWN feed
- Connector corrosion at the door jamb or switch connector
- Mechanical obstruction in regulator preventing movement and causing erratic signals
- Faulty switch PCB or membrane failure
Fault status
Status
B2205 - Left Rear Window Switch Stuck in Down Position (left rear power window DOWN input detected as stuck)
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
