- Window Motor Circuit Current Above Threshold
Diagnostic Fault Information
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 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 front window motor.
2. Test for less than 1.0 ohm between the control circuit terminal A and ground.
• 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.
3. Test for less than 1.0 ohm between the control circuit terminal B and ground.
• 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.
4. Connect a test lamp between the control circuit terminal A and the control circuit terminal B.
5. 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 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.
6. If all circuits test normal, test or replace the front window motor.
Component Testing
Window Motor
1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
2. Install a 25 amp 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.
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
* Front Side Door Window Regulator Motor Replacement (Service and Repair)
* Control Module References (Programming and Relearning) For DDM and FPDM replacement, setup and programming.
