Hey I’ve got a 2015 F-250 with a pair of Amp steps. I love them and have been working great for the years they have been on the truck. A couple weeks ago they stopped working. I checked the fuse and it had popped, so I replaced it and got them to go down, but after that no worky. So I tried some simple troubleshooting with no results. I ordered a new module, and that didn’t fix it. After some tinkering, I got both the new and old module to work in reverse, but only if the main nine pine harness was plugged in. If I plugged in the small harness it wouldn’t work again. I have tried every way to plug and unplug the module, put in the fuse, and unhook the battery. I can’t get them to work normally. So today I swapped the polarity of the motors. They work, but with one problem, the timing is off. The normal shut door delay happens when I open it. So if I open the door it takes a second to deploy, and then if I close it they retract immediately. They again only work with the nine pin harness connected, so I have no lights either. I have tried contacting amp multiple times and cannot get a hold of them. Does anyone have any solutions? Thanks. If any clarification is needed please ask.
Did you get this figured out? I did the exact thing you did reversed the polarity in the passenger side motor and they both deploy and retract when either door is open. Lights do not work either.
