Does anyone know which solenoid from the group of 6 controls the raise function? I rebuilt that six pack 3 years ago but it has developed this glitch. Also last week we replaced the HWH control box with a rebuilt unit so I don't think the issue is there.
There are 2 raise solenoids, one for each axle end. Is the problem just on one end or both?
If this problem cropped up coincident with that, it's highly suspect. Always start with the last thing done right before an issue appeared.
Dub, it appears the bottom 2 solenoids are the raise on both front and rear.
I had a raise issue before replacing the control box. The front will raise about 50 percent full bags with raise button held. Keith installed the control box and ran it thru a few cycles so I thought all should be ok. Ride height and leveling work as they should, just wont raise high enough for getting under the front of the coach. I replaced the control box because the touch pad wouldn't engage for leveling and the new one fixed that. I do realize the culprit could be in the control box but hope the six pack solenoid is.
What's the regulator for the front set to? At least in a 2000 and 2003 it hangs near the front axle and should be set around 60-65 psi. Could be you're not getting enough air pressure.
(This is the regulator that keeps the front from airing up too quickly relative to the rear. It's a ~$25 part at Lowes or Home Depot in the air tools department.)

I think this is Home Depot's version https://www.homedepot.com/p/Husky-1-4-in-Black-Air-Compressor-Regulator-with-Gauge-HDA70900AV/100082550
I have mine set at 70 PSI.
I will jack up the front axle and check that air pressure, it would be nice if that is the issue.
I can't get the 12" stands under the both fronts without raising to full and then raising the side too low with the side button and then putting the block in. I might try raising the front pressure next time to see if it fixes my issue.
Michelle, both axle ends on the front axle.
I find that it the coach is not absolutely level, the low side won't come up as high as the high side. Assuming a little more weight is being transferred to the low side in that situation.
The air control regulator was on 35 lbs. Turned up to 60 lbs and all works fine. I suppose the knob wasn't locked in allowing the pressure to gradually decrease. Over looked the simple.. Many thanks folks.
:dance:
Now go treat yourself to lunch with the money you saved
Just saw this thread Dub, glad you found the problem and it was something simple
This schematic might be of help for future reference when trying to locate things...
Lunch would be good but to much lunch to often is one reason :D this rig is hard for some folks to snake under. :D
well I put a kit in the rear six pack to rid another small issue in the rear so with both 6 packs done and air turned up on the front, a refurbished control box in the basement just maybe ALL of my HWH issues will leave me bee for a while. The turned down regulator on the front makes me feel a bit air headed but some days are just that way.. To much expect the worse here lately on my part. All well that ends well, thanks again for the input guys and Michelle. Trying to leave with no "known of" issues on our 3000 mile Quartzite trip.
