95 Chevy Pace Arrow - Auto Break Coming on in Reverse

There is an adjustable switch under the floor, under the steering column. You have to remove a sheet metal panel in the drivers front wheel well to access it. Its like a mini tie rod. It will be intuitive how to adjust it once you see it. It comes loose and looses its adjustment. I think the oldusedbear may have a photo of it.

In the mean time, put pressure on the column shifter toward neutral, with out going into neutral, when backing up. That usually will disengage the AP.
