tried yesterday to put ac on the disco 03 nothing
give me some tips to get started on this issue it just blows hot air

econ is not on and I checked the ac fault codes by pressing the 2 buttons and turning key on and had no codes
I would assume if it was a pressure issue it would give a code ????
I'm going to look at power at ac clutch next
any tips ??

Would a low pressure switch open not cause a error on the ac display code ??

Found the pressure switch open will need to check pressures. I'm a hvac mechanic but will need to pressurize system and etc
thanks for the input
