Any HWH control panel setting other than "Travel" should isolate the HCV's from the air bags. Those setting will isolate the air bags from all inputs unless "Raise", "lower" or one of the "up" or Down buttons is being actively pushed.

If you can get the rear raised at all, does it stay up? If not, then (when the control panel light "Travel" is off) if the rear drops you most likely have air leaks related to the bag installation.

When we have the HWH button for raise we have no air going to the new air drive bags we just installed.  When it is on raise mode does it get the air through the HCV or directly from the 6 pack??  
How does the 1/4 inch air line from the air supply tank get routed into the large air line that goes into the air bag?

Ok we think we have it fixed now. The HCVs were installed upside down. 1st issue. Then the pass side lifted but the drivers side not but was able locate an air leak on that side. Hopefully should work now. Thanks to everyone that helped us!!
