I've had these AMP RESEARCH power steps on my superduty truck for a couple of years. Never any problems until last week. We came out to the East Coast and now the steps won't come down. We noticed an intermittent problem when we first drove through areas with very high humidity. Now, in Florida, the problem is constant: the steps refuse to come down. I sprayed wd-40 in the contector at the amp research power module and at each hinge point. Dome light still functions and the door ajar light on the instrument panel works fine. Any suggestions? Anyone else have these problems?

well, i went out and tried a few more things. I first tried putting dialectric grease on the amp research connector at the power module. it made no difference. I then checked the inline fuse on the red power line connected to the battery. It was good. I then disconnected both positive and negative powerstep wires at the battery. I cleaned the positive connection and reattached them. I tested the steps by opening the passenger door, and the step came down!! But, it only worked for one cycle because when i shut the passenger door the step wouldn't go up. I checked the driver side door and the steps didn't move. I took a brief break, came back and removed the inline fuse for 30 seconds. I put the inline fuse back in and tested both doors. Now both steps cycle properly!! I hope it stays that way. Thanks

Dang! for the last two weeks the steps have been stuck in the down position. Yesterday i decided to go through the motions again and test the connections. I pulled the 30amp in-line fuse for the power steps, pulled and reinstalled the connector plug at the power step control module. I then spray all the door orifices with lubricant spray. Now the steps work. Let's see how long that lasts.

amp powersteps work with new control module

i called amp research last month and they sent me out another controller, since it was still under warranty. i plugged it in, but nothing works. i even used dielectric grease on the controller plug and pulled the 30 amp fuse to try and reset the unit. nothing. Well, I just needed to give the computer a day to set i suppose. With the new controller in place, the steps have been working great for the last 4 weeks. Amp research tech support was awesome and very willing to help. Big praise goes to them.
thanks all!! :icon_wink:
