Follow these steps carefully
Disconnect the vehicle's battery before working on electrical components. Diagnose first: on the 2015-2018 Jetta (Mk6/Mk7), a failing actuator usually buzzes or grinds when you hit the lock button, works intermittently, or fails from the fob but works from the interior switch.
Remove the door panel on the Volkswagen Jetta. Lift the panel up off the window ledge. Unplug the window-switch and speaker connectors, unhook the inner handle cable, and lay the panel face-down on a blanket.
Carefully peel back the foam vapor barrier — on the Jetta it must go back exactly as it came, or you will get wind noise and water leaks. Behind it sits the door latch assembly with the lock actuator. Unplug the actuator's electrical connector by pressing its locking tab.
Disconnect the lock rods and the Bowden cable from the actuator, releasing each clip in its proper direction — the cable ends have small plastic retainers that break if forced the wrong way. Maneuver the old unit out through the door's access holes — the window regulator rails are sharp, so wear gloves.
Reconnect the Bowden cable and lock rods in their exact original positions, confirming each clip snaps fully home; a half-seated cable clip is the classic cause of an inner handle that does not open the door. Reconnect the actuator's electrical connector until its locking tab clicks.
I confirm every cable clip snaps fully home — a half-seated clip is the classic dead-inner-handle, and I've diagnosed that exact failure before.
Reseal the foam/vapor barrier fully — press it back into place all around so there are no gaps for wind noise or water. Cycle it a dozen times; intermittent actuator faults often need several cycles to reveal themselves. Rehook the inner handle cable, reconnect the window-switch and speaker connectors, and refit the door panel onto the window ledge. Reconnect the vehicle's battery.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
