2005 Freightliner Sprinter

WHEN TRAVELING IN HOT WEATHER AND RUNNING BOTH THE FRONT AND REAR AIR CONDITIONER, THE VEHICLE STALLS. THE STALLING OCCURS WITHIN MINUTES AND UP TO HOURS AFTER BEING RUN BUT ONLY OCCURS WHEN SLOWING THE VEHICLE DOWN (IE: CONSTRUCTION ZONES, STOPPING, TURNING). THE VEHICLE DOES NOT IMMEDIATELY RESTART BUT HAS ALWAYS RESTARTED WITHIN 3 MINUTES. SINCE WE DO NOT LIVE IN AN EXTREMELY HOT AREA THE STALLING USUALLY OCCURS WHILE VACATIONING (ARIZONA, CALIFORNIA, UTAH, FLORIDA, NEBRASKA). WE HAVE HAD THE VEHICLE INSPECTED AT TWO DIFFERENT AUTHORIZED DEALERS AND WERE TOLD THEY "WERE UNABLE TO DUPLICATE THE PROBLEM" AND AT ONE POINT WERE TOLD THAT A RECALL PART WAS INSTALLED TO CORRECT THE PROBLEM BUT WHEN WE TOOK IT TO ANOTHER DEALER, THEY KNEW OF NO RECALL PART AND THEY CONTACTED CHRYSLER ON OUR BEHALF AND WERE TOLD THE FOLLOWING: "ENGINE STALLS WHEN DRIVING. INTERMIT - ONLY HAPPENS WHEN OUTSIDE TEMPERATURE IS OVER 100 DEGREES OR AFTER VEHICLE HAS BEEN DRIVEN FOR A FEW TO SEVERAL HOURS OPERATING AS DESIGNED AT THIS TIME 704 DRBIII DIAG NO CODES IN ANY MODULE, ROAD TEST TO TIJERAS AND BACK, WAS UNABLE TO DUPLICATE CONCERN, VEH OPERATING AS DESIGNED, ON HOT DAYS WITH AUX A/C ON, THE EXTRA LOAD ON ENG MAY CAUSE STALLING AS AUX AIR IS STAND ALONE AND NOT INTERFACED TO PCM IN ANY WAY TO COMPENSATE IDLE. CHRYSLER HAS NO FIX FOR THIS CONCERN, OPERATING NORMAL AT THIS TIME." IT SHOULD BE NOTED THAT THE AUX AIR WAS PURCHASED AT THE TIME OF SALE. IT WAS A NEW VEHICLE AND WE ARE THE ONLY OWNERS. I HAVE PAPER DOCUMENTATION FOR THE AFOREMENTIONED INFORMATION. *TR
