Our 1998 buick lasabre air condioning will not blow out vents. everything works, but it wont blow out vents. it will blow on window vent and blows on floor vent.but the middle vents will not blow out.


ck to see if your vaccum hose if broken at the engine vaccum connection, it may have a vaccum hose split or a bad vaccum switch/actuator, if it has manual a/c, if it has electronic a/c then your mode actuator is not working.

Does this have auto temp control where you set the temp number or does it have a knob you set 1-5. I'll bet you have auto temp. and you need to replace the blower control module under the hood.

Blower motor vent selection switch not working


the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

2000 Buick LeSabre air only comes out on the floor


They have two types of air conditiong controls. AUTOMATIC & MANUAL . Your mode switch maybe bad if manual. If automatic the head is probably bad and they are sold as exchanged units only. If manual check all circuits to see if 12 volts has continuity

Air won't come out of vents, but will from defrost and floor.


if it switches function even only a few then the problem is not the vacuum source (if u had no vacuum it would default to defrost mode) the problem is the dash control head vacuum mode control switch, i don't think u can just replace the switch, u have to buy the whole climate control module.

Front defrost wont work in my 92 4runner


Yes it is cable operated and something is probably disconnected. Remove your glove box so you can get a better look at whats going on.

Dash Vents wont blow as selected


THE COMPRESSOR IS SUPOST TO RUN NOT MATTER IF IS IN HOT OR IN COLD MODE SOME TIME THERE IS A POSITION WHERE THE A/C WILL BE OFF AND THIS IS ON THE KNOB CONTROL WHERE YOU SET DEFROST AR FT VENTS
ALSO ON THE THE SWITCHING FROM DASH TO FLOOR CHECK FOR ANY VACIUM LEAKS FROM THE ENGINE COMPARMENT SINCE MOST OF TIMES THIS IS CONTROLED BY VACIUM ACTUATORS
