Title: 2004 GMC Yukon – Both Rear Doors Lock But Won’t Unlock 2004
2004 GMC Yukon SLT 5.3L (GMT800).
Both rear passenger doors suddenly stopped unlocking at the same time a few weeks ago. They still LOCK perfectly fine using the key fob and interior switches.
Both front doors and the rear hatch lock/unlock without any issues.
I’m thinking it’s a shared electrical issue rather than both actuators failing simultaneously.
Anyone experienced this before? Is there a specific relay, fuse, or common wiring circuit I should check first? Trying to avoid throwing parts at it.
