Help 2004 itasca sunova stop lights stay on constantly

[Liketoobike]

Just started yesterday and i did break the right side mirror, though all wires are still intact. no explanation, well, ok the "auto park" light stays on all the time. We purchased this unit from individuals and picked it up at the shop, the guys there said that light sticks on sometimes... wonder why they didn't take care of it or say what to do... anyway, appreciate any insight from anyone on this item as we are traveling now for a week.
