Need heater/AC controls before winter

My heat/AC slider in my 1995 Si is broken and stuck on air only. Winter is coming up and my car would be completely undriveable without heat. Does anyone have an extra control module they would be willing to sell me? They pop up on Ebay sometimes for around $15-30, but I need it soon, and I assumed that it would be WAY overpriced to buy it from a dealer. I know this could be in the classifieds, but it's urgent and not too many people look in there. Thanks for any help.

Oh yea, and I'm in east central Illinois.
