Question about 2000 Buick LeSabre

1 Answer

2000 Buick LeSabre air only comes out on the floor

Air only comes out on the floor no matter what is selected at the HVAC dash control. I checked the voltage at the mode door actuator module and I get 12v. at the wire comming from the HVAC10A fuse, Battery negative on one of the wires, and on the third wire the voltage changes depending on what is selected at the dash control. I changed the mode door actuator and now it blows out the defrost and no where else. Can someone tell me what the voltage signals are supposed to be for the different control selections- vent , heat, defrost etc. What could the problem be?

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

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.

Hot air always, no matter what temp control is set at(1993 Buick)


There is a blend air actuator on the passenger side that causes the blend air door to stay open to heat no matter what. It's below the left side of glove box, facing dash, and you can work it by hand and get it to close. If that works, get a new one. They're very easy to install.
