So I have a new failure mode that has been driving me crazy on my coach and I finally figured out the problem by chance and luck. I have been having issue where the coach would not raise or lower to travel mode, the HWH display would say it’s in travel mode but the suspension was not adjusting accordingly. So I thought I had an issue with the six pack solenoids. I put my hand on the travel solenoid in the front and noticed it was not hot. Well I was right by the control box up front in the bay just below the driver so I decided I would check to see if maybe it blew a fuse. All the fuses were fine, but for some reason I thought to fiddle with the plugs were the wires go to the solenoids off the control board and “click” there goes the solenoids and I hear air start flowing. I was in a bit of a hurry to get on the road so i did not do much more investigation at that point, especially after I had just been under the rear of the coach replacing a brake relay valve because I could not air up. So a couple times I had to mess with that same plug on the control board to get the travel solenoids to get power. Well looking closer it appears that one of the pins that is soldered on to the board has gotten hot and has come loose. So I was basically pushing it back in where it would make connection. Only issue is bumps in the road etc are probably messing with the power to the solenoid. I have not yet fixed this, I am going to remove the board and try to solder the pin back on the board.
