Yes, I know what it does, and this ice cube relay has a set of contacts that are wired in series with the door open relay (44) but of coarse no one marked up the prints to show where the coil is for that ice cube and what pulls it in. Not even sure that is our problem but I am leaning towards it. The only thing that bugs me is that you can hold in on 42 when it's leveling in and then the car will stop and open the doors.
