Cimpressor stays engaged but vent air is only cool. would like to ad a lb. of coolant but cant find the low pressure orifice. Can you help? BTW it an Ultra.
If your compressor is staying engaged adding more freon is not going to help. Just explained on this forum on a question that is having the same problem as you. Go to this question and check out the answer I gave them. You have the same problem. ( My 2007 Chevy Impala blows warm air but the compressor is running and it is charged with freon).
