Hi Everyone!

looking for a bit of help... my power running boards work perfectly when you open or close the door, i keep them well greased!! noticed today while getting a car wash that the button to enable or disable them isn't working. It used to! i would drop them down all the time to go through the wash. only thing that's changed is i replaced the battery about a month ago. Could it be the switch? should i pull the fuse? try the relearn process? anyone had this issue?

Just an update, i replaced the fuse. it looked like it blew but reconnected again, it was definitely burnt at some point. Didn't fix the issue though still no response from the button... im wondering if the short took out the switch? but the switch also has peddle adjustment, lane keep assist and tc and they all work. Would anyone have a wiring diagram for this? is there another fuse maybe?

Well finally had some time and did a bit of digging and managed to figure it out. One corroded wire on the smaller plug into the power running board control module. Reconnected it and the switch to enable and disable is back working!!!
