Air system question

It might get long..2001 U-320 42'. Last fall we took the HWH control box out of coach and sent it to HWH. It would no longer level and raise and dump. It would go into travel mode with no issue. Found a fuse in box it kept blowing. Service at HWH was fantastic. Got it back quick with small bill attached and we put back in coach. Basically had same problem only fuse would not blow. Control panel lit up correctly which it not do prior. We discovered yesterday some issues inside box..somethings not plugged in or incorrectly. Long story short...the coach now will dump..but if you try to raise..only the rear raises. So here's what it will do. You can raise and dump the rear at control panel in coach. It will dump and raise side to side. It will dump the front on control panel also...but what it won't do is raise in the front end. You can here it send a signal up front but no action. AND it won't self level with two punches on the level button. The red light goes on and off three times but no response. You can physically here the signal out of the box..(I guess that's how you would relate) but nothing happens...when you shut it to OFF on panel it goes right into travel mode as it should..we had a service call slated at HWH but never got a return call. Any thoughts from the brain trust??

Did you also send the touch pad in to HWH? Also trouble shoot the control cable for possible damage

Mike,

With what you describe:
Check to see if the raise signal is getting to the plug on both raise coils on the front 6 pack.
Check to see if your raise coils on the front 6 pack are good.
