This isn't buick related but is common car problem related so i hope this is the right place to post this...just looking for some help. I have a 1996 mustang gt daily driver..i know i know...cheap and fun though. I have had the check engine light go on after an emissions test and some new catalytic conv....the error is p1464- Air conditioning demand out of self test range.:rant: Has anyone encountered this problem before and know what it takes to fix? I am selling the car as we speak and was about to make the transaction when the light came back on...maybe my car doesnt want to leave. Any thoughts?
