HWH Control Box Location

My leveling jacks stopped working. The slides (also hydarulic) work just fine.

Reading earlier posts, I find that there are fuses in the control box. I have not been able to find it to check. Reading earlier posts, I have checked locations that worked for them but no joy for me.

I have a 2001 Adventurer 35U.

I hear a clicking somewhere under the dash and will check further.

I have downloaded the HWH trouble shooting guide and it will be helpful once I find the control box.

Did you try the Winnebago Technical Help Line?

Or sometimes there is a Yahoo Group which you can join where only Winnebago Owners are members. I am sure someone there would have your answer right quick.

On my 2002 UA the HWH box I think is mounted under the dash on the front fire wall to the left of the steering column

I tried the help line and after 25 minutes on hold listening to them blather on about the superior windshield design (ironic in view of all the rust complaints), I gave up.

Back to looking, I think that I should be able to trace wires anyway.

Mine too! What a miserable place to put something that needs to be in place for diagnosis. The geniuses at Winnebago have outdone themselves with this.

I can barely reach it to even get a finger on it.

Good tip, thanks. Back to work.

Yep look in that area, that's where it was on my 2003 Suncruiser.

Final answer on non-functional levelers. There is a fuse just above the hydraulic motor that blew in an odd way. The fuse part of the fuse was just fine but the leg of the fuse had blown off in such a way that I had to replace the fuse holder.

Trying to follow the HWH flow chart was a non-starter as I could see the LEDs in the control box.

Look at these schematics that another poster posted that was having trouble with his surround sound system. One of the diagrams show the location of the HWH leveling system controls near the drivers floor.

identification of the system is important to do the correct diagnosis. the control box for a 310 or 610 system is an aluminum box about 6 x 8 inches and three inches thick. no leds. no plexiglas cover.
in your year coach, it is normally located under the dash on the left side of the steering column.
a 325 or 625 system has the control box mounted to the end of the pump. it has visible leds and a plexiglas cover.
if the fuse was the one in the #10 blue wire, that damage is normally caused by the protective cover not being in place. or missing.

Hey Bruce, does "final answer" mean it's all working OK now?

My jacks quit last Jan and I spent several days troubleshooting and figuring out how the system works with some help from the HWH factory tech.

If you still have problems, maybe I can help.

Thanks for the offer. I think that it is fixed. I did some light weight testing yesterday and everything worked. I will do more exhaustive testing today.

I do wonder why the fuse blew its brains out like it did.

What size (amp) was the blown fuse?

I'm pretty sure some small % of fuses come pregnant with defects and then it varies as to when the problem gives birth. Sometimes extraordinary heat, long wet or cold spell, or one of those killer bumps at a RR Xing will stimulate the birth of the problem. I worked in the electronics industry for 40 yrs, and traveled to far corners of the country to solve some pretty vexing problems.

When my HWH jacks quit (slides worked), it was giving me a "Not in Park" light which seemed pretty straightforward to fix. If I left it on for 15-30 min it would start to work again. But 3 days later I'm still fiddling around, gave up and sent the control board and keypad to the factory to fix. If both had to be replaced it would cost around $700 with shipping. It turned out to be a bad relay on the main control board and cost me only $135 with shipping. Hope I get 10 more yrs of service now.

Bill

It was a 40 amp fuse. Sorry about the fuzzy picture but you can see that the actual fuse part is OK and that it blew the leg off. I had to replace the fuse holder as the other leg was stuck in the old one.

Luckily, I had purchased a 10 ga. fuseholder in Quartszite. They are hard to find.

I have done my serious testing and am satisfied that I have a fix.
