2005 Buick LeSabre AC fan will not shut off when car is not running. Have to pull the fuse to stop the fan.

Asked by Oct 04, 2017 at 11:57 PM about the 2005 Buick LeSabre Custom Sedan FWD

Question type: Maintenance & Repair

I cannot shut off the heater or AC in my 2005 Buick LeSabre unless I pull the
fuse under the back seat. Some have said it is the Resistor Mocule, others say
it is the Blower Control Module. Too expensive to replace both at one time. Any
ideas would be more that gratful. Thanks

There is a blower control module that often fails and gives the symptoms you have. I am attaching a picture of the location on a 1993 Riviera....do not know exactly where it is on your LeSabre. They are about $80 new, but plentiful at Pick-n-pulls. It is the part #1 in the exploded view, the other picture is the unit itself, yours may look a little different


It would not let me post 2 pictures....here is the location


you have a gm
