I've emailed HWH this afternoon and am hoping some of the talent on the forum might be able to provide some insight. My email is as follows:

"I have a 1992 country coach affinity built on a Gillig chassis (Gillig #46GEDO41OM1042224). I believe my HWH air leveling system is a ML6629?

The coach was parked for about 4 months. after picking up and using last week, the leveling function is unresponsive. When I press the "air" button on the HWH control panel, the green travel light goes out and the only lights that will illuminate are certain yellow level sensing indicator lights....no other lights on. I can not get any response out of the control panel; no adding/exhausting with my raise/lower buttons, etc. The only thing that seems to function properly is the return to travel mode both automatically and manually.

I have tried unplugging the ribbon power connection from the back of control panel and replugging in. I have also found the silver control box on the other end of the ribbon and confirmed that all fuses are good.

Any insight and/or parts availability would be greatly appreciated."

Try pressing the button twice!

Already tried. Pushing twice is what I usually do to engage auto leveling; once to take out of travel mode and allow for manual leveling, twice to engage auto level.

I have to push "off" to use the dump button.

Assume that you have turned the leveling off and then back to automatic (two presses) in your testing to see if it will reset.

Also, you could turn the battery off for a bit and then back on to see if will reset.

Unplugging the harness should have done the reset for you the same as disconnecting the batter would too.

I have no experience with that age unit, so hoping others will pop in to add help.

All I can suggest is the basics of checking that all the grounds are clean.

Will follow the thread, and wish you the best... Please share back what is determined to have been the problem.

Thanks Smitty. I'll definitely update as a solution is established.

HWH usually has at least one 12V fuse near the pump motor assy. Mine are inline blade-fuse holders in the wiring bundle.

^^^^interesting. I was thinking the only fuses were located in the large silver box. I'll have to hunt down the ones you are referring to.

Still pending a reply from HWH. Hopefully I can at minimum identify my unit and obtain troubleshooting literature.

Go here NOMENCLATURE to identify your system.

Then, maybe this page http://www.hwhcorp.com/ml54800_srvc....WH__Slide_Outs
will have the service manual.

Worth a try until HWH gets back to you. They have been slow responding to their customers. I've used the service manual for my system to help trouble shoot problems.

Thanks for the links.... I was able to educate myself tremendously.....thank you!

Update: although the service manual was informational, it didn't spec out my issue specifically. Through my puttering, I Was able to find my control box (attached to front if firewall). After removing the cover, I was disgusted to find a mouse nest....no Bueno. There were no blown fuses however, there were some chewed wires and mouse urine on the control board circuitry which I'm almost positive is causing my issues. Pursuing a rebuild of the board at this point....will update as I experience progress.
I wish all mice would die a slow and painful death....effectively leading to extinction.

Do the following.

Blow out the area to get all loose stuff out.

Take a bunch of photos.

Zoom in to magnify everything then use computer screen to see better.

If you can remove the board get a can of denatured alcohol and place the board in a coffee can or zip lock bag and fill with the alcohol and let it soak for about an hour.

Get a 1/2 inch wide cheap paint brush and cut it to about 1/2 inch long.

Take board and place in a bowl and pour fresh alcohol in bowl and carefully and gently scrub it to loosen any remaining stuff then blow it clean.

Look for traces that are damaged.

Take photos to post here for suggestions.

Set it in a warm place for a day to be sure it is dry.

While soaking clean the area and each wire connection.

When finished put it back together and try it.
