2004 SIGNATURE DASH HEATER QUITS AFTER APPROX 40 MINUTES OF RUNNING ON HIGH(A/C OR DEFROST) COOLS DOWN AND STARTS AGAIN SAME CYCLE AGAIN AGAIN AGAIN GETS HARD TO SEE OUT OF THE WINDSHIELD WHEN YOUR DRIVING IN SNOW STORMS. I HAVE CHANGED RESISTOR PUT IN PART # 4C2Z-19A706-AA ( MOTORCRAFT) ???????????????? JOHN

John, does this happen in all selected speeds or just one speed? If it happens in all speeds then it is usually the motor. If one speed effected only then it is the resistor pack.

Your AC system was made by SCS Frigette out of Fort Worth which went broke. They have started up again as Victory Climate Systems but SCS is used in the link
