Mine went the same way on my Eddy a couple of years back.
Called the recovery truck as I thought the whole car was knackered, then felt a bit stupid when the guy said there's no issue driving it, just you'll have no aircon.
Cannot remember the exact part that went, but it was fixed quite easily by the dealer and once regassed all fine.
It was under warranty at the time, so not a clue on cost of the fix, but seem to recall it was a quick fix.
Enjoy your driving trip.
