Dorman Door Lock Actuators - Reliability-Tested up to 20,000 Cycles
937-513 - Dorman DLA

Dorman Door Lock Actuator Cycle Tester
Differences Between IDLAs and DLAs

Integrated door lock actuators contain complex electronics that integrate a complete door latch assembly, including the lock and unlock mechanism, into the actuator. Standard door lock actuator are mechanical components connected by a series of rods and cables to the door lock mechanism to lock or unlock the vehicle door.

Don’t sacrifice safety with a cheap replacement door lock actuator.

Dorman delivers higher quality, more reliable solutions that are thoroughly tested and built for safety.

DLA and newer integrated door lock actuator (IDLA) designs are critical components that should pass strict Federal Motor Vehicle Safety Standards and perform properly over the long term.

  • In Dorman testing, competitor actuators have failed after just 700 test cycles – or roughly just six months of simulated use.
  • Dorman actuators are tested up to 20,000 cycles – equal to 15 years of use.

  • Common failure modes include electrical burn out or excessive wear to internal mechanical components

    5 Stars
    Great replacement part!
    This part worked perfectly on my 2005 GMC Yukon SLT. Considering it is a Chinese made part, only time will tell if it lasts 10+ years like the original actuator. If you're wondering how difficult it is to replace, do not fret. It's as simple as replacing a fuse. The dealership wanted $500+ for the part, excluding labor. So, I believe it's fair to say you will make the correct call. Looks like Amazon does not want me to include instructions, so I have included pictures in this review. When I purchased the actuator, I did receive instructions so you will be fine. One final note, The instructions will not tell you this, but I do recommend removing the 3 cables, and blue fasteners (See pic with plier on blue fastener). This will provide less obstructions when removing the whole lift gate latch actuator bracket, and easier actuator replacement. I hope this helps everyone. Good luck.
