2001 Malibu air conditioner Control Knob

[mycol]

One of the knobs for the air conditioner is busted at the point where it attaches to the peg. The three dials are interchangeable so I can use one of them when needed but I’d like to get it replaced. Does anyone have a spare or know where I can get a replacement? Any help would be appreciated.

Most auto parts stores carry a line of parts labeled "Help" and they offer a package of assorted knobs.
