Circuit/System Description
The driver door module (DDM) and front passenger door module (FPDM) 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 switch is in the ON position. |
Conditions for Setting the DTC
B3205 00
The DDM or FPDM 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 DDM or FPDM has detected excessive current flow on a window motor control circuit.
Action Taken When the DTC Sets
B3205 00
The power window motor operation will not be attempted whenever this condition is present.
B3205 0B
Power window motor operation will be disabled for the current ignition cycle.
Conditions for Clearing the DTC
B3205 00
When the fault is no longer present, the door switch changes the current DTC to a history DTC.
B3205 0B
| • | The DTC will be current for the entire ignition cycle. The DTC will be a history DTC the following ignition cycles until the conditions for setting the DTC have been met. |
| • | The door switch will clear the history DTC after 50 fault-free 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
Ignition ON, observe the operation of the driver and passenger 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.
- Test for less than 1.0 ohm between the control circuit terminal A and ground.
- Test for less than 1.0 ohm between the control circuit terminal B and ground.
- Connect a test lamp between the control circuit terminal A and the 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 window motor.
| ⇒ | If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the door module. |
| ⇒ | If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the door module. |
| ⇒ | If the test lamp is always OFF during either of the commands, test either control circuit for a short to ground. If the circuits test normal, replace the door module. |
Component Testing
Window Motor
- 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.
