Question about 1997 Jeep Grand Cherokee
AC compressor is operating OK and Clutch pulley is turning. Freon is charged to capacity. All lines are ice cold. At initial startup the air is very cold as it should be. After a little while the air is warm. Someone suggested that where the lines come into the passenger area, there are two "doors"-one for AC and one for heat. They said the AC "door" is stuck closed. Does that sound reasonable? I have checked fuses and they are all OK. I read about an AC bypass switch. Can anyone help with some advice?
Well the blend door theory would work if the ac never got cold. But you say it starts out cold and then gets hot.
Its possible the system is freezing up due to lack of air flow thru the evaporator, or a blockage in the freon lines.
You would need to watch the high and low pressure gauge readings as the system gets warm.
You may need professional help for this.
