Fuse Box locations
2008 Winnebago Destination 37G workhorse chassis. Cab AC compressor clutch not engaged, so I thought I would start with fuses. Chassis manuel gives general location and says refer to coach builder ...

Can't help on finding the fuse box, most likely due to age the system may have leaked enough refrigerant to prevent the pressure switch from turning on the compressor which is more likely than a blown fuse.
The way A/C systems are setup on modern vehicles they have a pressure switch connected to monitor the refrigerant pressure. If not enough pressure the switch will not allow compressor clutch to engage and is a very common problem..
If you know someone who has a set of refrigerant gauges, have them check to pressure on the system.
If a bit low may just need a little top off, if very little to no pressure then may need to find the leak and repair.
Another possibility is the compressor clutch gap is too wide to engage due to wear.. You can pull the connection going to the compressor and check to see if you get voltage with A/C turned on.. If you get voltage then the clutch may be worn and not able to engage. Some clutches the gap may be adjustable by changing/removing the shims on the clutch. If gap can't be adjusted then a new clutch is in order.
