Thanks Diana for the question,

The fact that they won't open with the key or the button inside shows that they are disabled. This could be due to the on/off switch in the overhead console is turned off or the control module sees an issue and is not allowing them to open.

If this switch is in the on position then we would need to have the vehicle scanned for any diagnostic trouble codes (DTCs). This would indicate if there is an issue with a sensor or control module that would explain why they are disabled.

There is a chance that there are no DTCs (unlikely but a chance) and if that is the case then we need to have the button pressed while monitoring it with a scan tool. This way we can find out if the module is receiving the signals to open them. My guess would be that it is receiving the signal but the control module cannot send the command to open them. The only thing I am concerned about is each door as its own control module. So if they are both not working from either the key or button, then it is unlikely that both modules failed at the same time.

This is why the on/off button makes sense that it is off or there are DTCs pointing to what our issue is.

Let me know what you find out and we can go from there. Thanks
