Thought I’d share my experience to confirm Fletcher’s observations: Readying for departure from home, we got a little rushed and did not complete our pre-departure checklist before moving our rig from its parking pad to the driveway to hitch up the toad. Unfortunately and unnoticed, the entry stairs did not retract as they should when the engine started.
They dragged through a low embankment on the right side of the driveway, severely bending every link of the three steps.
After paying for this mistake, with new steps installed, I discovered they did not automatically retract on engine start.
Checking fuses, left side under the dash, I discovered the “STEP ALARM” fuse #24 (15 amp, upper right corner of fuse block) to be blown. I was so happy! I produced a new fuse and put it in. But when I turned the ignition on, the stairs, once again, did not retract. Bummer. That’s when I went searching for help here and found Fletcher’s post. Sure enough I found my “COACH HTR” switch was on HIGH! Turning it off and plugging in another new fuse brought my new stairs’ automatic retraction back to normal! Conclusion: stair auto-retract and coach heater are both powered through step alarm fuse #24.
That leaves me at the same spot as Fletcher; how the heck does one get at the coach heat blower and motor? Looks like a lot of talk on the subject, but the definitive, step by step answer still eludes me. I'm determined to have my coach heater fully functional again. Help!
