Try having a professional check that the collant lines have not perished. Also have them check the thermostat and that there is actually gas in the system. The warm air suggests that the unit has no gas.

Dou Therm Brisk Air not running


Turn the ac off go up top the coach and remove the cover. Look for fan blockage, Wasp, mud dauber etc. Caution if it is wasps they will chase you off the end of your coach. Take some spray with you. If there is no blockage the fan motor is toast.
