Squirrels building nest in my A/C

[Weldon]

Hope this is the place to post this. Have a dometic penquin 13500 air conditioner on the front of the fifth wheel. Twice now they have got inside the shroud and chewed the wiring making the unit inoperable. This second time they built a nest inside as well as chewed the wiring. Question, how do I keep them out? The way the shroud is made they have no trouble getting inside. I know you can purchase the vinyl covers but don't think that would stop them.
Appreciate you suggestions!

Wrap a piece of chicken wire or similar, with smallish holes no bigger than 1/2", around the A/C unit, specifically on the surfaces where they gain entry. I've used short pieces of picture hanger wire like twist ties to fasten it in place. It's a great deterrent for unwanted entry into a variety of things, chimneys, soffit vents, any small opening that squirrels and chipmunks frequent. It allows air flow, too.

The 5er is in the country, only get there every 2-3 weeks. Thumbs up on the stew though.

Trap them. Start a relocation program.
