we were recently on trip and when we parked the rv the spot was almost level. we put our slides out and i noticed that the slide side should have been brought up some. we tried to used the leveling system but nothing happened. (it had worked prior to this trip. I brought the slides in and tried it again. I noticed that now the park/emergency brake light indicator on the leveling control was now on when you pushed the leveling on button. rv was in park and the emerg brake was on. I didn't know what elese to do. we returned home yesterday and parked it. I had it in park and emer brake on and still has red light indicating park & emer brake need to be on. Any Ideas??????
