- 99 lesaber limited
Hello, i have a 99 lesabre limited. The ac/heat will only blow thru the center vents. No floor or defrost. Also driver side will blow heat and ac, the passenger side will only blow ac. I replaced 1 vacuum line and when i did it started blowing out the floor and defrost at the same time and would not switch to vent. I am a little lost here. Any help would be greatly appreciated, thank you.
