2003 Great West Van slide out won't go in

[pkak]

Slide out wont go in. No response when dash key to move slide out is turned. Red indicator dash light doesnt light. Engine battery power guage shows charged and van starts fine. Is the slide out powered by the engine or aux battery?

While I'm not familiar with the RV that you have, most of them power the slides from the aux battery(coach battery). Have you checked any voltages? Do you know the condition of the coach battery and is it only 1 battery? Have you checked the electrolyte levels in it? I suspect that your battery is the problem.
