The A/C vents cut its air flow while on a trip from Tucson to San Diego. It was about 100 degrees outside but the engine never heated up above normal. I could hear the fan blowing but it was not coming into the car. The mid-fan setting was barely a breathe of air. The following day it worked fine again on a sort drive. Should I have the dealer check it out before I go back on the second leg of the trip?

definitely go to the dealer you may have multiple fault codes ,more than likely it is a blower motor resistor ,could even be a control unit software flash ,hope this helps you with your choice ,
