337RLS Rear jacks nonfunctioning

[Jefferson Beifuss]

My 2015 337RLS had a problem exiting a Blue Beacon truck wash a month or so back. They washed it and I had them brush it down (my error). As they had me pull out, the rear jacks had been deployed, but they stopped me just outside the bay. I retracted the jacks, extended them again, retracted them, all appeared good, I went home and parked my rig. My jacks would no longer deploy. I replaced the switch, thinking it had been damaged by the brushes. No dice. The jacks don't appear bent, but, of course, could very well be slightly. How do I find the electrical lines to see if I have a blown fuse, since neither jack deploys right now? They both slid on a wet, concrete surface for less than the trailer length, but it doesn't take much to damage these. I do have JT Strong Arms installed on the front and rear, which may have saved my bacon on bending the legs. Doesn't make me feel any smarter, however.

Any ideas for how to proceed on repairs?

If GC 2.0 with a crossarm between rear legs(like front legs), try hand operating them with hand crank thru right side frame hole.
Power is run to rear switch from covered area behind battery.

There is a 30 amp fuse near the battery that will blow if they go up to high.

Since I'm pretty sure all readership was waiting with baited breath for the exciting conclusion to this yawner, I finally, after spending a limited season of not much use of the camper in the rest of 2021, contacted a mobile repair service to look at the rear electric jacks that were damaged last year. Some findings;

1. We never did find any fuses that would have protected the jack motor.
2. When the truck wash jammed the switch in the full extend position, it burned out the jack motor. Somehow, I was able to retract it that one time at the wash, to get it home, but after that, the motor was toast.
3. I have now had the motor replaced and it works again (it is still not fused)

Thanks again, Marcy and Gene, for replying last year, when I posted originally. It was appreciated.
