ziptie12 October 25, 2012, 20:29MasterHow hot is it down ther in florida ? Still above 70 during the day? probably normal operation if car is just sitting idling with no other source of airflow to cool it. Is the A/C also on?(or defrost- that defaults to comp. operation)

Maybe something is not completely plugged in or got unplugged without knowing , when the hose repair was done. Hope I'm on the right track for you. Keep us posted. Thanks.
