We live in FL. A/c indiscriminately shuts off, fan works but blows only air - has happened four times.

Shuts off on a short trip and on road trips especially when it’s hot - again, we live in FL! Problem checked out by various Hyundai dealerships but to no avail. Two well versed service managers recommended a service engineer be called in. Husband did contact Hyundai corporate as recommended. When Hyundai called they tell us no service engineer will be called in unless the a/c is then malfunctioning in an actual dealership plus she said service managers shouldn’t have told us to contact them!!
