My issue now is that I cannot get the 3 bolts that hold the housing loose to remove the motor. They seem to just turn and turn, and will not drop down to remove the assembly. Do you have any suggestions?
Nuts that are spinning (now that they have been loosened by you) aren't tack-welded to the frame the motor. Grab a flashlight and see if you can verify that, but 99% sure that's your issue.
Originally (2 years ago) my step problems were alleviated by tapping on the motor and I assumed I'd gotten a bunch of wet gravel stuffed in the motor gears
by driving on some of the roads in Alaska. I made a scrap metal screen to go behind my right rear tire & mudflap and pop-riveted it into place and my step problems disappeared for a year (or so).
After removing the step motor I'm not so sure that was the problem... those gears and powerful motors would crush tiny pebbles easy.
After some "detective work" and gently tugging on the wires, I found the yellow wire coming out of the control unit had frayed and finally broke off which stopped the step operation completely. Bought a new control unit, installed (easy to do) and it worked great for another 6 months. (This assumes
that your step has a control unit...? Some don't)
Anyway, there are a number of things that can cause the motor not to work so go to the Kwikee website and check out their trouble-shooting guide and then search
here for lots of relevant info. BUY A TEST LIGHT if you don't already own one?
Mucho help right here... good people with good ideas
