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.
Conditions for Setting the DTC
B3205 00
The DDS or PDS detects a short to ground or short to voltage on a window motor control circuit.
B3205 0B
During 5 occurrences of power window motor operation in an ignition cycle, the DDS or PDS has detected excessive current flow on a window motor control circuit.
Action Taken When the DTC Sets
The driver or passenger 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
DTC 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
Igntition ON, observe the operation of the front 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
- Ignition OFF, disconnect the harness connector at the appropriate front window motor.
- Connect a test lamp between the control circuit terminal A and control circuit terminal B.
- Ignition ON, command the window UP and DOWN by using the window switch. The test lamp should illuminate when commanding the UP and DOWN states.
- If all circuits test normal, test or replace the front window motor.
| ⇒ | If the test lamp is always OFF during either of the commands, test either control circuit for a short to ground or an 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. |
Component Testing
- Ignition OFF, disconnect the harness connector at the appropriate window motor.
- Install a 25A fused jumper wire between one of the control terminals and 12V. Momentarily install a jumper wire between the other control terminal and ground. Reverse the jumper wires at least two times, the window motor should perform the UP/DOWN functions.
| ⇒ | If it does not perform as specified, replace the window motor. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
