Wiring diagrams are not available as the manufactures to not publish them. There will be a series of circuit breakers that control the slide, jacks and awning. The circuit breakers are small rectangle 12v breakers with a terminal stud on each end. Some are automatic reset and others have a small black button on the side that must be reset. On a motor coach you will find these in a storage compartment and they probably will not be labeled. On travel trailers they will be located near the front of the trailer and often times will be linked together with a copper bus bar. On 5th wheels they will be located in the front storage compartment close to the battery box. Follow the positive lead from the battery back and you should locate them relatively easy. Next, make sure the nuts on the terminals are tight and using a test light make sure that you have power to each terminal on each circuit breaker. If you do not have power to the output side of the breaker then it is bad and will need to be replaced. They are amp rated so make sure you replace the breaker with the proper amp rating. I.e, 30amp or 40amp. In some rare cases the inline circuit breaker for the jacks is relatively close to the jack behind where the switch is mounted.
