DTC Descriptors
DTC B3205 00
- Window Inactive Over Current Fault
DTC B3205 0B
- Window Motor Fast Over Current Fault
Diagnostic Fault Information
Circuit/System Description
The driver door switch (DDS) and passenger door switch (PDS) control the power window functions through the power window motor up and down control circuits. The door switches monitor the control circuits for fault conditions when up or down operation is requested prior to activating the function and during operation.
Conditions for Running the DTC
* Battery voltage must be between 9-16 volts.
* The ignition is ON.
Conditions for Setting the DTC
B3205 00
The DDS or PDS detects a short to ground or short to voltage on their respective window motor control circuit.
B3205 0B
The DDS or PDS has detected excessive current flow on their respective window motor control circuit.
Action Taken When the DTC Sets
The affected power window will be inoperative.
Conditions for Clearing the DTC
* The DTC will be current for as long as the fault is present.
* When the fault is no longer present, the DTC will be a history DTC.
* A history DTC will clear after 50 ignition cycles.
Diagnostic Aids
B3205 0B can be set due to excessive physical resistance in the window regulator assembly. Ensure proper mechanical operation of the regulator assembly prior to replacing electrical components.

Circuit/System Verification
Observe the operation of the power windows while commanding each window UP and DOWN by using their respective window switches, each window should perform the UP and DOWN function.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
2. Connect a test lamp between control circuit terminal A and control circuit terminal B.
3. Ignition ON, command the window UP and DOWN by using the door switch. The test lamp should turn ON when commanding the UP and DOWN states.
• If the test lamp is always OFF during either of the commands, test either control circuit for a short to ground or open/high resistance. If the circuits test normal, replace the door switch.
• If the test lamp is always ON, test either control circuit for a short to voltage. If the circuits test normal, replace the door switch
4. If all circuits test normal, test or replace the window motor.
Component Testing
Important: When performing the following tests, make sure that the window motor is not all ready in the position the test is attempting to produce.
1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
2. Install a 25A fused jumper wire between the control terminal A and 12 volts. Momentarily install a jumper wire between the control terminal B and ground. The window motor should perform the UP or DOWN function.
• If the function does not perform as specified, replace the window motor.
3. Reverse the jumper wires; the window motor should perform the DOWN or UP function.
• If the function does not perform as specified, replace the window motor
