Kwikee Step problems solved
The quick answer is that I solved two serious problems with Kwikee Steps.
1 - On our 2010 Journey, the problem was the step motor. One of the motor commutator brushes was stuck in it's guide and intermittently made contact.
2 - On our previous 2007 Adventurer, there was a broken wire in the electrical adapter, just beyond the step motor harness.
With the "stuck brush" problem, removing and dismantling the motor, allowed me to smooth the channel/guide for the stuck brush. It works reliably now. Strange, but the problem occurred more when the temperature was cold. Below 45*F. It lead me to believe it was "sticky" or lack of grease, but that was not the case. There was plenty of good grease in there. For the average DIYer, you may want to get a new motor, because re-assembly of one is a bit quirky.
On the Adventurer, there was a short (maybe 6") wire adapter plugged into the motor harness. In it was a small resistor and diode. Inside the tape wrapped bundle, one of the tiny wires broke from fatigue and needed to be soldered.
Either of these problems can cause severe damage to your steps, when you don't know they are still extended. Don't ask how I know!!!
