It sounds like you have a couple wires run backwards on your Lippert powered steps. Its hard to say exactly which wires are wrong but most likely a power wire and ground is backwards. The best recommendation I can give would be for you to go over the wiring and verify everything is connected correctly.

The green wire gets grounded to the chassis.
The white wire gets connected to the power switch which then goes to the positive battery post.
The yellow wire gets run to the a keyed power source, power only with ignition on.
The red wire connects to the positive battery post for the motor.
The brown wire gets connected to door switch.

I attached a diagram that shows how all of the connections should be made also. If the wiring checks out let me know what info you can find for the door magnets as you might have the wrong set.
