Chute Switch(?) troubleshooting

I have a P1524E and the auto chute won't always rotate (currently not at all). From my reading, likely a switch issue (part #1728969SM). Does anyone know if it can be opened up? No obvious way that I can find. I took the "button" off hoping to access the contacts from the top but it's sealed. There MAY be tabs on the sides, but pushing on that area hasn't worked. I think this is just a few years old, which means it could be the newer design that I've read referenced as hopefully solving the old problems, perhaps doing so by sealing it up better. But I'd like to get in to see if I can clean off the contacts (if that's the problem). Besides testing for continuity (see below), is there a good way to test while it's hooked up? I read somewhere someone recommending connecting a test light, and if a local store sells them I could do that, but don't know where/how I'd connect it, anyway.

I actually have a place close by that sells the replacement cheap ($35), but unfortunately today is Sunday and big snow is coming tonight. And I think they only ship, despite being close by (and maybe closed today).

Fwiw, I tried testing for continuity but couldn't get any. Probably because it's indeed broken, but I also wasn't sure which pins to test. It has 10 poles, and not sure which should show a closed circuit when I depress the rocker switch each way. I did test each of the pairs on the end with all of the other pins, with negative results on any combination, which could very well be because it's indeed not working. But wondered if anyone knew for sure which should be correct ones.

Thanks in advance for any help!

Hi and welcome to the forum!
Have you watched this video from Taryl Fixes All?
Hopefully the video will help you troubleshoot.
And as Taryl always says: "There's your dinner!"

Yeah, I did. Thanks for the suggestion, but his is unfortunately slightly different (older?) I posted a question on that video's chat, too, to see if they've encountered my type.

Here's a better picture of mine (though MAYBE a different version?) This is what one side looks like; the other has a single indentation/slit, where I hoped I could pry it open. But I'm not sure if that's what it is. This one appears to be angled, the bottom 3/4 of it, whereas mine is not. But that could be a distortion from the camera lens.

Maybe someone on the forum will be able to help you disassemble the switch. From your pics it looks like it just snaps together, but of course that's the trick, to get it apart without destroying it, LOL.

Here's what the top looks like with the rocker cover off, in case it helps. The two rounded items are glass (lights?), not contacts. The contacts are sealed (from the top) underneath. I don't even understand the mechanics of this type. From the looks, it was made to be better at keeping the elements out. And probably did, but didn't prevent pitting of the contacts.

Does this help any?
Sealed
Vehicle Rocker

There are some contact schematics about half way down.

Boy, awesome find! Mine appears to be on page 8, the Above Panel Rocker Switch. If only I could read schematics And if only it weren't as I suspected, "Designed
to meet the severe environmental requirements of the construction and agricultural vehicle markets, the SVR is sealed at the front and back of the switch, and meets the rigorous
sealing requirements of IP68."

So, not meant to be opened, it appears. Could dremel it and reseal with glue, I guess. Geez... Worse than an iPhone. Great that it kept the elements out; now if only they had designed it to not pit so easily (assuming that's what's going on?!)

On that, any thought on whether it might be the chute motor, and how I could tell?

Thanks for all the help; great forum!

I am guessing that this is how your switch works. Power and ground (+/-) are brought in at pins 2 and 5. Holding the rocker one way and you connect terminals 2 to 3 and 5 to 6. Hold it the other way and you connect terminals 2 to 1 and 5 to 4.

Thanks to dbert, I would troubleshoot by starting with seeing if you are getting voltage at where the 2 and 5 pins plug into the switch. If you are getting voltage then go from there.
