FYI. Sometimes it takes a lot of hrs to find these things. 2 fuse blocks under the dash pod on left side. Lower block has fuse labled cig lighter. It's not. I didn't take the time to find out what it went to just put a ? mark on it. Actual lighter fuse is on the upper fuse block, 20 amp bottom right.

Also on lower block the 15 amp labeled "step alarm" also goes to the back up monitor, coach heater (the fan/vent on floor just back of the mtr cover), antenna reminder and HWH wiring. The Winny diagrams show wire "KE" going to all these, problem was the drawings end at the I/P convenience center. Called Workhorse, they sent their drawings which shows the "step alarm" fuse going to all this stuff thru the I/P. Heck, i didn't know the step alarm wasn't working because the step has always worked....unless they just meant the light on the dash which also didn't work.

Found my problem to be the fan not turning blowing the fuse. Next project fix fan. Haven't started yet..any one know how to get to it? Hope this FYI saves someone some time and frustration

Thanks for the information Fletcher0077 and welcome to irv2.
If its your cooling fans on your radiator try backing the blade in the opposite direction a few times may free up the shaft of motor and it may become free wheeling again.
Enjoy the forums and do post often.

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!
