I have a 4.0l '94 YJ with the afterthought AC fitted. It bolts to the bottom of the heater assembly as if Jeep added it as an extra!
Anyway, it works fine. The air is cold, the fan is quiet...but......it cycles on and off too often.
As I am driving the air is cold coming out of the vents, then the compressor cycles off and the air gets warm. Then the compressor cycles back on and the air gets cold, then it cycles off etc.
It's as if there is a thermostat somewhere telling the AC that it has cooled the car down to the temp set and now it is keeping it there. My problem is that it is still 100degF outside and it ain't cold enough in the car!
So, is there some sort of temperature sensor that thinks the car is cold when it isn't?
Any ideas gratefully received
ps. Had the gas topped up a while ago and it made no difference.
