I see that you have the sister coach to my Journey 42E. I too am having trouble with the slide locks. I can only find 2 locks located in the full wall and none in the other slides. What was your fix to get the locks to work? My problem seems to be no power to the lock switch, from what I can tell everything from the switch to the locks is in order. I found on 15 amp circuit breaker located in the rear panel with the coach batteries. Are there other breakers that I am miss? Thanks for any help you can offer.
