A/C shuts down in stop & go traffic, Why?
I'm pulling a 29 ft 5th wheel and my a/c is shutting down at low speeds and under acceleration from stop lights. It cool great once up to hightway speeds. I had the freon checked and the guages read with good numbers. While idling the high side goes up to 450 and then the fan turns on and the numbers fall back to the 250 range. The air from the center vents is 39 degrees.
What controls how the fan is activated? Would my running a superchip programmer affect this?
Any and all help is appreciated.
