Ran into a problem I cannot seem to resolve and need help if available.

On our 2015 Thor Challenger 37TB suddenly and without fanfare slides, overhead bunk and awnings stop working. Initially thought it was Rapid Camp but after extensive troubleshooting worked the problem forward to the front interior electrical buss. Ignition/Accessories Relay 2, 3, 4 seem to be where the problem gets first seen. If Relay 2 is removed, the slides operate. If Relay 2 is replaced, slides operate. Once the ignition switch is turned on and then off, slides do not operate. Pull Relay 2 and replace, slides again operate. Turn the ignition switch back on and then off, slides don't operate. I am attaching the wiring diagram. The common feed to each of these relays is "Ford Ignition Input".

Also, steps fail to operate correctly. With ignition switch in off position, step switch on and open the door - steps deploy. With the ignition in off position, step switch on and close the door - steps retract. Again sounds like the ignition switch lockout.

I am attaching a copy of the wiring diagram. Anyone with experience with this issue or anyone with advise for resolving, please comment. Gonna get old fooling with these relays.

PS: Andrea Hans (Thor CSR) spent the better part of 90 minutes helping me. Thank you.
