my 2011 Escape the doors no longer auto lock at 20km and the horn has quit working at the same time (I believe). checked horn fuse; its good.
There are options to turn these features on and off in the vehicle settings menu (auto lock), the horn however if its failed too it might be a wiring issue. The only thing you can do is grab a wiring chart and multimeter and start testing wires, or have a professional track it down.
Sounds like a BCM (Body Control Module) problem. Both the power locks and horn are controlled by the BCM. HTH. -Jim
