Interesting reading. My steps have their own mind also. I also my steps will not stay out when I use the switch by the door. Very annoying to have them go in and out every time the door opens and closes.
Joseph I checked the step swith with OHM meter and it is good.I checked the function by using alternate 12 volt supply to white wire at the swith and the unit works as it should. So problem is the 12 volt supply to the step switch. I just don't know where the fault is located I will try again in the morning with fresh eyes to look for blown fuse. Thanks for the info on the 20 amp fuse but per manual I should find a 5 amp fuse for this circuit
