i have a 93 grand am se 2.3 with 170,000 miles. i cannot get the air to blow out of the correct areas on the ac. it seems to want to stay in the middle blowing in my face even when i put it on another setting. sometimes it will go to where i have it set and then it will come back down. the ac compressor is not plugged up. i was told i have a vacum leak. is this true? its really annoying when i want the heat on the windshield or my feet and it in my face.
