Amp Steps quit working

I bought some amp steps a couple years ago. Well yesterday the steps stop working, I checked all the connections that go into the harness and they were all good. When I checked the fuse, it had blowned, so I went to put a new one in and it blew it. So I disconnected the both motors on the steps and disconnected the ground and power from battery, put the fuse in and when I went to hook up the power, it blew again. I am thinking that maybe it might be the module.

Q1. Do you have the controller mounted under the hood ?

Q2. When you replace the fuse, do you have a door open ( so the steps are triggered, trying to open ) ?

Q3. When you unplugged the step motors, this is at the motor on the step ?

Could be one of the wires to the motors has rubbed through the insulation and is grounded on one side ( what rcantu posted about ), if the steps cycle when you apply power the 1st time. If the steps do not do this, I would suspect the controller.

You will need to unplug the connector on the controller so the motor leads should be open, then check each wire to ground for continuity ( meter set to the ohm position ).

Not sure if the steps cycle the 1st time the controller gets power or if you have the door open.

Yes the controller is under the hood, I unhooked the harness going into each motor, tried putting the fuse in and it kept blowing so I know its not the motors since there was no power to them at all(motors are on the steps). Ive checked every wire and everything is fine, I must have gotten a curse. I will try disconnecting the harness from the controller and see what happens. I think its the controller since it has been a couple years and it gets a lot of use.

following this thread.... mine still work, but I figure they've gotta die one day. Interested to hear what AMP has to say about the situation.

Neither side works correct?

Nope both sides are dead, that's why I am pretty sure its the module, at least I am hoping that's it

This rules out the motor, but not the wiring on the truck between the controller and the step ( motor connector on the step is where the motor unplugs ? )

Q2. When you replace the fuse, do you have a door open ( so the steps are triggered, trying to open ) ?
- The wire would still have power on it even with the motor disconnected, this is why I asked if a cab door was open when you install the new fuse.

How did you check every wire ?

You mean you are guessing it is the controller. It might be, but doing some basic diagnoses would confirm this, rather than buying a new one and installing it to maybe find the same thing happens.

Yeah I see what your saying, hopefully tommorow I can play with it some more. I'm gonna disconnect the harnest from the controller that feeds to the motors and see if a fuse blows.
