Heater completely stopped working but the blower motor was still good?

My heat had completely stopped working but the blower motor was still good. So, I was trying to check the Climate Control Module, and I ended up breaking the passenger side temperature control "knob". It's actually like a little lever that slides up and down. But anyway, now the driver's side I can make hot or cold but the passenger side stays freezing cold all the time. And I've actually broken the plastic piece on the inside that the little temperature lever thing slid up and down on. And that control module costs a couple hundred dollars which with it being the holidays.I don't really have that much to spare right now. Is there any other way that I can make the passenger side temperature hot or just completely shut all air off from going to the passenger side?
