I have a 2014 Holiday Rambler vacationer 30 SFS that the front facing AC vents in dash was not working. After checking the vacuum lines, I found the vacuum motor that opens the front facing dash vents had failed. My question is how to remove the vacuum motor. In the dash there are 4 hoses hooked to box. From engine compartment the vacuum motor is imbedded in back of box and bolts to remove are inside box (see photo). I looks like I remove the vents box from inside the engine compartment but I am not positive.
