2007 Entourage A/C

My wife's 2007 Entourage w/ 40,000 miles suddenly developed an A/C problem. Two days ago, the A/C was working fine and yesterday morning it was blowing nothing but hot air. Any suggestions?
TIA, Bill

Suggestion? Go see your dealer. The AC charge is covered for 1 year. While it may be the charge lost, it could be something electrical, like the compressor clutch or a switch. That should be covered from what I read. 5 YEAR / 60,000 MILES NEW VEHICLE LIMITED WARRANTY Covers nearly every new vehicle component
Covers repair or replacement of any component manufactured or originally installed by Hyundai that is defective in material or factory workmanship, under normal use and maintenance.
Following components covered for time and mileage limits indicated: - Radio And Sound Systems (i.e. radio, cassette tape drive mechanism, and compact disc player): 3 years / 36,000 miles - Paint: 3 years/ 36,000 miles - Battery: 3 years / unlimited miles (100% covered 2 years / unlimited miles; after 2 years and within 3 years, 25% cost of battery and 100% labor cost covered) - Air Conditioner Refrigerant Charge: 1 year / unlimited miles - Adjustments: 1 year / 12,000 miles - Wear Items: 1 year / 12,000 miles (e.g. belts, brake pads & linings, clutch linings, filters, wiper blades, bulbs, fuses)

Check the A/C fuse in the underhood fuse block. 2006 and newer Hyundai models have an increased frequency of problems with compressor clutch field coils having insufficient resistance. If the fuse is blown, the resistance of the coil is probably too low. Okay to replace the fuse to get the A/C working temporarily again, but there's no telling how long it'll remain cooling. If you do replace the fuse, save the old one and take the van (and blown fuse) to the dealer for warranty service. Be sure to explain to them them the symptoms and which fuse you needed to replace.
