Door lock problms
What's up guys. About 4 months ago I had the first problem with my power door locks. The right rear stopped working. About 2 months after this the left rear door lock stopped working. Now just yesterday my driver door has stopped. Now I have seen threads about the lock actuators but I think it's kinda funny that 3 would fail within 4 months. This is an 2007. Any other ideas

Here's some information from the 2007 DR FSM:
08 - Electrical/8N - Power Systems/Power Windows/Diagnosis and Testing
DIAGNOSIS AND TESTING - POWER WINDOWS
WIRING VOLTAGE TEST
The following wiring test determines whether or not voltage is continuous through the body harness to the front switch.
Refer to the appropriate wiring information.
1. Remove the window/lock switch.
2. Disconnect wire connector from back of switch.
3. Switch ignition to the ON position.
4. Connect the clip end of a 12 volt test light to Pin 14 of the window switch harness connector. Touch the test light probe to Pin 10.
If the test light illuminates, the wiring circuit between the battery and switch is OK.
If the lamp does not illuminate, first check the fuse in the Totally Integrated Power Module (TIPM). Check the circuit breaker located near the park brake pedal. If fuse and circuit breaker are OK, then check for a broken wire.
POWER WINDOW MOTOR TEST
If the power window motor is receiving proper current and ground and does not operate, proceed with motor test.
1. Remove front door trim panel as necessary to gain access to power window motor wire connector (Refer to 23 - Body/Door - Front/PANEL, Door Trim - Removal) .
2. Disconnect power window motor wire connector from door harness.
3. Using two jumper wires, connect one to a battery (+) source and the other to a good ground (-).
4. Connect the Negative (-) jumper probe to one of the motor connector terminals.
5. Momentarily touch the Positive (+) jumper probe to the other motor connector terminal.
When positive probe is connected the motor should rotate in one direction to either move window up or down. If window is all the way up or down the motor will grunt and the inner door panel will flex when actuated in that one direction.
6. Reverse jumper probes at the motor connector terminals and window should now move in opposite direction. If window does not move or grunt, replace the motor.
If window moved completely up or down, reverse the jumper probes and cycle window to the opposite position to verify full operation.
If motor grunts and does not move, verify that regulator is not binding.
