We have an Auto-Trail 2007 Tracker and are having problems with the 12v Omnistep. We think its the motor but can't get the step out to dismantle it to get at the motor. At one point the step was coming in and out of its own accord but now it is permanently in. I have spoken to Auto-Trail and they say that it must be connected to the 12v which it already is so they were no help at all.
