anybody recognize this switch?

Hey just wondering if anyone knows what this switch might go to..it has 3 connectors on the back, labeled "L" "B" and "H" and has 58024 stamped into the plastic, and also 323 3500 on the metal side, does it look familiar or does anyone know what it is? thank you.

Looks like a fan blower motor switch, late '70s or ealy '80 judging by the knob style. Could be an F-body rear window defogger switch.

See if there is some sliding to it between the first click and the second click. It may be a delay wiper switch, Should hav a 3rd click.

Looks like it would fit a late 70's to mid 80's van.

It looks a lot like the '79 F-body rear window defroster switch (date code 0999) I have. Is the stem spring loaded?

With only three terminals, it can't be a wiper switch.

The '79 F-body rear window defroster switch I have in front of me is very similar, with the same three termianls. It has a date code of 0999 and is part number 3747324.

Is the stem on your switch spring loaded and does it return to the center position after pushing it either up or down?
