Help -slides will not extend

All compartment doors are shut good and I have already tried in and out of gear- parking brake on and off several times - no luck. I just can't figure it out. We have been on the road for 42 days now. This is the first time this has happened.

Are there any lockout switches on the cargo doors that might cause that.I had an RV that had them on it. Try parking brake off and on a few times.

Tried no engine - no luck. I reset all the breakers - no luck.

One thing to try is that if it's like our 03 Phaeton, the slides do not operate when the engine is running.

On our previous coach, a 98 Fleetwood PA, there was a fuse in the battery compartment on the wall above the batteries that you had to push to reset if it tripped but I suspect yours is likely different than our PA.

My book doesn't show fuses for the slides. I don't know where to start checking

Fuses?
