Foretravel Owners' Forum

Let's start my issue with what I know:
2001 U320 single slide, my air compressor hasn't cycled at all, using the engine with air on both gauges normal, the green travel light won't come on, trying raise or dump No Joy, BUT when I push those buttons the lights come on the panel....
...also the slide air bladder will not deflate, looking at the lock pin box in the basement I see no lights (leads me to believe no power to the system)
The airbags are solid, though I can tell that the gap between the tire and arch are a little lower than normal (not high enough for travel light)
I recently had work done on my travels in Nac to and from Mexico.... Slide adjustment, air issues on fwd step, plus some other stuff. When traveling back home from out west, I did notice that the travel light would fade in and out, but within a short 1/4 mile it would be solid green.
Now what I don't know..... where the power for the system comes from, or if there's a relay/reset switch or circuit breaker. Hoping that maybe someone has experienced this or has knowledge to send me in the right direction. Thanks for reading and to this forum.

The travel light just lets you know it's in travel mode and there is a 7.5 fuse in the aluminum box in the
large storage compartment. Why it would fade in and out I have no idea unless there is a poor connection
somewhere.

Have you tried the simplest of all solutions?  Pull the pad up and make sure the connector for the board is fully seated.  Your scenario happened to us on a trip back home from Branson.  Drove me crazy with dash dings popping in and out of travel mode.  Took it to shop and they checked everything.  All sensors, interlock pins and finally called HWH.  They thought it was a solenoid but since it was intermittent they said either replace all solenoids or wait to complete failure.  Then I remembered a thread on the forum about the power connector for the pad.  That's what it was, and was also the simplest fix.

I will try the simplest.... and fingers crossed, that's it
Thanks, sometimes you get so wrapped up, ya don't think of the simple stuff. I'll let ya know if it works.

Unfortunately the simplest solution, which I was hoping for, did not work. Back to square one....

I think might only be for the aux compressor, but there is a resettable 12V breaker in the basement for "HWH Comp".  It's one of those little button ones.  Look at the left of the 12V automotive schematic:



There is also a 10 amp fuse behind the panel in front of the passenger seat for "HWH Mem", looks like #49.  10 amp would be a little lightweight for the entire HWH control, though.


ETA - studying this second one shows fuse 11 is for the HWH CPU.

On my 08 there is a separate contactor on the hydraulic pump that supplies power to the leveling and slide controls. That also effects the air compressor for leveling and the slide out room seals. Without it all the control indicators work but nothing actually moves,

That will be the 9700 wire from the control box to the Auxiliary compressor.  That is separate from the pressure switch on the compressor which maintains the tank to keep the bladder inflated.  As Dennis mentioned, when you press a raise button of the control pad, or turn the key to deflate the bladder prior to moving the slide in, it sends a signal to the aux compressor and calls for air. 

We had an issue a few weeks ago where the 9700 wire was not connected to the compressor.  It took a while to figure it out as that was not only preventing the slide bladder from deflating, it was also shutting down the HWH system the next time the auto-level called for air.  It masked itself nicely when leveling upon arrival as it only required a dump, but would go shut down with excess slope and require starting the engine, letting off the parking brake, and resetting the system.  At that point we could deflate the bladder and bring the slide in.  Once I found the 9700 wire not hooked up the the compressor and got that sorted, leveling, slide and travel light sorted itself out. (Note: on our coach, if the slide is out it will not go into travel mode. Not sure if that's the case for everyone.)

I stumbled across this following the HWH manual where troubleshooting guide said the test for 12V on the 9700 wire.  Once I went to  do that and saw it disconnected, it was a ah-ha moment.  :)
