Write-ups and videos from owners, forums and specialists on removing and fitting this part. Summaries are ours; follow the link for the full steps, photos and torque values, and credit goes to the original author.
Numbered steps for when one door stops locking: door card off, pivot pin and latch cable released, three T30 screws (one hidden under the weatherstrip) out, then the lock/latch assembly comes out so the actuator can be separated and the mechanism lubricated.
Tools mentioned: T30 Torx, Phillips screwdriver, side cutters, cable tie, dry graphite lube
Cheap fix for early (non box-shaped) E32/E34 lock actuators: open the housing carefully around the circuit board and swap the worn DC motor for a same-size Mabuchi FC-280SA. Tedious soldering work; the author says to just buy a new actuator if you hate fiddly jobs.
Tools mentioned: Small wrench, pry tool, soldering iron, replacement Mabuchi FC-280SA motors
Only for the early actuator style.
