The right door lock,power window and speaker stoped working

In the fuse panel on the inside check the larger fuse marked 'POWER' it supplies voltage to the windows, sunroof and also the power door locks.

Have you removed the drivers side door panel and checked the wiring harness to see if it is loose or if there is any wires shorting out? If the locks works from the passenger side but not the drivers side you can rule out any fuses or relays. The lock is apparently not getting voltage from the drivers side wiring harness, and in all likelihood you have a loose connector at the controls inside the door panel. Check that first and see if that doesn't solve your problem.

The thing to do first is have the vehicle hooked up to a professional grade scan tool an have it checked for DTC'S in the driver door module , an to see if the scan tool will talk with the module !
Then if no codes are present check for battery power an good grounds at the module ! You have to take the door panel off the door to get at the module . I have one of these modules out in my tool box , I got it at the auto salvage yard . $10.00
In order to control window operations, as well as other door functions, door modules must be powered up. Battery voltage is supplied by the rear fuse block, through separate circuits, to each door module. Each door module is separately grounded through a ground stake. Additionally, the door modules use these power and ground supplies to provide voltage and ground to their associated window switch, and to provide voltage and ground for door lock operations. The front door modules also use these power and ground supplies to power the window express up sensors, and for outside rearview mirror operation .

How to test computer controlled door locks

You need to see a wiring diagram to see how the ignition switch allows or sends power to that 30 amp fuse. The switch may turn on a relay (maybe the ignition relay) that sends power to the fuse panel. Or the run wire out of the switch may itself turn power on at the fuses. You may have a loose connection behind the fuse panel.
Get a test light, pull the fuse, and check for power at the fuse terminals, with key on. One terminal for the fuse should have power. If not, power is lost between the ignition switch and that fuse. If it does have power, and windows still don't work, check the wire from fuse panel to the master switch-loose or poor connections, maybe a partially broken wire. If it looks good, check the ground wire for the windows. The ground wire originates at the master switch and will go back into the cabin to a nearby ground, possibly behind the left kick panel. If still no help, someone may need a volt- ohmmeter to start checking continuity of wires, voltage drops, etc.

Had the same issue, both doors controls stopped working at the same time making the power windows, power mirrors, and power door locks all stop working. However, when the engine was off the door lock would work. It could be many things, but the fact that they all quit working at the same time suggested it wasn't an individual motor. I pulled the door main control panel and with a wiring diagram checked the continuity of each switch through the electrical plug out back. You can get the diagram off kiatechinfo.com

The main door control turned out to be good (expensive part). It wasn't getting power to the control, which meant it was either a broken power wire or a bad ground interrupting the circuit. The easiest to test was the ground. I ran a small wire from the negative battery and put it in the main ground wire on the back of "main door control panel". Worked perfectly on both doors. Apparently the ground for the door accessories are somewhere on the floor board, they corroded from a leaking sunroof. Never could find the bad ground so i just ran a new ground wire to it from the engine (drill a screw into body and attach wire)

Look for broken wires leading into the driver's door. Have you already checked for a fuse problem? The windows and locks may be fused, or they may be on a circuit breaker. Sounds like power is not getting to the master switch, or the ground for it is lost. If you have a voltmeter, you can check for power and ground right at the master switch. The switch will have one hot wire to it with the key on, and one ground wire from the switch back into the cabin and then to ground somewhere, probably close by.
Ground a voltmeter or test light, pull the master switch connector apart, turn key on, and probe the connector for one hot wire. If you have it, good. If no power, again check for broken wires at the door. To check the ground wire, put positive lead on the hot wire, and the negative lead into the ground terminal source at the connector. If the ground is good, the meter will show battery voltage, or the testlight will light up. If the ground is lost, you will get nothing on the meter or testlight.

--------This will help.Thanks.

I would check under the boot to see if you have a broken wire under there. That is probably where the wires run for your power windows.

1-check relay panel under hood for loose/not fully inserted relay
2- check for blown fuse
3 do you have a switch on drivers door - says WINDOW CONTROL/LOCK ?- cycle this
ps if your jumper wire get windows up- its not a ground issue at door- sounds like bad ground at relay block if no blown fuses

at times in the drivers side door where it opens there is a boot. A wire may have corrosion on it , and possible snapped
