Tips for a great answer:
If the test lamp is always ON, test for a short to voltage on either control circuit. If the circuits test normal, replace the DDS.

Passenger Door Switch (PDS)
Body Control Module (BCM)
Rear door power window switches
Power window motors in each of the doors
PWR WDO Circuit Breaker
Power Window System Controls
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The driver master control switches are integrated into the DDS. When a power window switch is activated in the up or down positions the DDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the DDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist and during window motor operation the DDS continues to monitor the motor current to verify proper window motor operation.
The DDS controls the passenger window by a serial message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation.

Check this circuit breaker
RETAINED ACCSRY PRW BRKR 30 amp. located in the left instrument panel fuse box . if the breaker is good check power B+ at the drivers door switch . connector 1 terminal b yellow wire . Sometimes the wires inside the rubber boot coming from body to door break .

The passenger door switch (PDS)
The body control module (BCM)
The driver information center (DIC)
The rear door lock/unlock relay (LBEC)
The door lock actuators in each of the doors The rear passenger doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. The energized the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.
Do you know what the BCM is , body control module ! If you do not know about this stuff I strongly suggest you to it to a ASE certified repair facility ! Save yourself some money an aggravation !

The door control module actually consists of the door's Electronic Control Unit (ECU) and the switches or buttons integrated into one assembly. There are two of them: the driver door module or DDM (as seen on the sample diagram below) and the passenger door module or PDM, which is on the right front door. These modules are programmable.
They are also called driver door switch (DDS) and passenger door switch (PDS), so perhaps you can rephrase your search.
