Like y'all I have had lots of issues with my power door locks. The dealership replaced the driver side front actuator under warranty. The passenger front failed soon after that out of warranty, and I replaced it. Now both those are acting up again.

There's also been intermittent issues with both rear doors but neither has been replaced yet.

My question is, is it possible there's some electrical problem other than simply replacing all the actuators (again for the front doors)? Like a relay or something that could be causing the problems? It just seems odd for all four to be having issues, especially when 2 have already been replaced.

Appreciate any help!

Thank you,
Brandon
