It's always somethin' - part 2, or 1 or ?

This is probably "It's always somethin'" part 1, because it occurred before the electrical problem...

When we stopped in Conroe, Texas, since we would only be there two nights, we intended to put the passenger-side front slide out. Our typical plan is to use the "big" slide on the front driver's side if we're going to be somewhere 3 or more nights, and to use the passenger front slide (not as deep) for stays of 1 or two nights. When we tried to put out the passenger front slide in Conroe, the slide locks unlocked, but the slide motor did not seem to engage and the slide did not move. We thought back, and it seemed that the last time we used the front passenger slide was at Licon Dairy in El Paso. Bummer, but not going to deal with it for now - we just put the front driver's side slide out.

When we got to the Cajun RV Festival in New Iberia, Louisiana, Carl had a little time that he could take to do some debugging. 

He located the two controllers for the slides on the passenger side of the rig -- they are located in one of the bays underneath.

He tried doing some wiring changes to see if he could get the slide to move.

The front switch that usually moves the front slide would not work...

... but with some additional manipulation to the wiring...

... he was able to get it to move using the slide switch in the bedroom. So, the motor of the slide works.

We decided we had done enough debugging to know that it wasn't a loose wire somewhere, but rather something that needs more diagnostics and probably parts that we don't have. We called Newmar (we are on a "cancellation list" to be notified if an appointment opens up at the factory service center for May) - they were not very hopeful that we would get in there and gave us a couple of potential places to try to get it serviced. One was a service center in Elkhart that we had visited back in 2020 (https://journeyinamazinggrace.blogspot.com/2020/08/a-show-and-repair.html) - so we called them and were able to get an appointment in May. It means that we need to leave the farm 3 days earlier than we had planned, but we're hopeful they will be able to take care of the problem for us!
