1998 Buick LeSabre Question: A/C vent problem
Vac to the control head or bad control head, - backyard tech
Safely rise front right side of the car. Take a look under the car's fender - under fender, front of the tire. Check the VACUUM line leading to the small TANK . If the rubber connection to the tank is broken or leaking, fix it. You do not have enough under pressure in the system. When idling, air goes to windshield and legs (default setting). With more RPM, more vacuum, your AC works sometimes. Regards, ZU - drdozl

it MAYBE your B C M COTROL MODULE IT CAN BE REPAIRED ,BUT TRY AND FIND A USED ONE AND CHECK FOR A BURNT CURCUIT ON THE BOARD A BAD BCM WILL MAKE YOUR CAR DO CRAZY THINGS OR IT IS THE CLIMATE CONTROL HEAD WHICH I WOULD CHECK FIRST ,U CAN BUY A USED ONE CHEAP PRE TESTED - bacal123
air out of passager a/c vents rear vent also blows same as front drivers side can this be repaired and what will be the cost.
Turn A/C on, compressor runs and so does fan- no air coming from vent. After short time air starts to flow and it gets cool. I suspect a slow acting air valve or deflector. Thanks
a/c fan stays on after the car is turned off. air comes through the windshield vents and the vents on the floor even when there are no keys in the ignition.
Recently recharged a/c system and have been getting cold air on the passenger side but not from the driver side. Checked for vacuum leaks but nothing apparent. Any suggestions?
never blows out of mid vents
