Cruise control will not work .

IIRC that green wire goes to the heater blower switch. Use a piggyback connector on the green wire then your cruise power wire. Make sure both blue wires are connected to the brake switch. It “should” work unless there’s an actual issue with the servo.
I'll take a jumper wire from the key operated heater blower fuse box and touch it on the plastic brown plug end and see what happens. then also connect that blue wire that is dangling there to the plug end .. . cross my fingers . see if it turns it on at least.
