Sometimes answers can be slow in the restoration section of the forum. You can try some things to improve your chances.
For example, if you had included something like "Bay Breeze Siezed" in your title, somebody who has had something similar happen to their A/C may chime in.
Also, you can find folks with similar traliers in the model-specific section of the forum. That's where I often start when I want info about my exact trailer and it's systems.
Unfortunately, I don't know anything about that specific A/C. In general, I'd suspect that the shroud is held on by screws or rivets. If rivets, they'll need to be drilled out.
To find your fuse box, start where the power cable enters the trailer. It probably won't be too far away. Look in closets and cabinets.
I just clicked the search link at top in the blue bar and entered "bay breeze." If you do that, too, you'll find plenty of reading and information.
And welcome to the forums. You have come to the right place, and we all want to hear about your progress and experiences with your Ambassador.
