I have a 1993 Buick LaSaber today I changed the spark plugs and wires, did a oil change, and changed the belt. After I was done everything seemed OK but then the wife took it and came back saying the heater/AC controls don't work. The AC works but I can control the direction of the air flow. Its stuck on defrost. It will shut off but that's the only function that works. I figure I must of bumped off a vacuum line but don't see anything. Any ideas where I should look?
