ON JUNE 3, 2018 UPON CRANKING THE TRUCK, THE A/C BEGAN BLOWING EXTREMELY HOT AIR TO THE POINT IT LEFT A RED MARK ACROSS MY HAND AFTER FEELING FOR THE VENT WAITING FOR THE TEMPERATURE TO COOL DOWN. IT WAS 90 DEGREES OUTSIDE AND RAINING SO WINDOWS COULDN'T BE ROLLED DOWN. WINDSHIELD REMAINED FOGGY DUE TO HUMIDITY WITHIN THE TRUCK AND I HAD TO PULL OVER FREQUENTLY WHEN DRIVING IN ORDER TO WIPE THE WINDSHIELD TO BE ABLE TO SEE. TWO CHILDREN IN THE BACKSEAT OF THE TRUCK, ONE IN A REAR FACING CAR SEAT WERE BEYOND OVER HEATED AND WELL ON THEIR WAY TO HEAT EXHAUSTION BY THE TIME WE REACHED THE DEALERSHIP DUE TO TEMPERATURES REACHING ABOVE 95 WITHIN THE CAB. TRUCK WAS SEEN AT DEALERSHIP AND WAS ADVISED DUE TO VIBRATION FROM DRIVING, THE A/C DISCHARGE HOSE WAS CRACKED ALLOWING THE HEAT FROM THE ENGINE TO BE BLOWN DIRECTLY INTO THE CAB OF THE TRUCK. HOSE WAS REPLACED AD A BRACKET ADDED TO IMPROVE THE STABILITY OF THE HOSE AND REFRIGERANT ADDED. EIGHT MONTHS AND 4 DAYS LATER, A/C SUDDENLY BEGAN BLOWING HOT AIR AGAIN. WAS ADVISED AT THE DEALERSHIP THAT THE HIGH SIDE SERVICE PORT WAS NOW LEAKING AND NEEDED A VALVE REPLACEMENT AND REFRIGERANT ADDED AGAIN.
