ok, so re-calibrating the climate control didn't work out. Im not sure I really did it right. Anyway, the overall problem is that the car gets pretty weak heat. New radiator, and I flushed the heater core too. Any ideas? Oh yeah, the "air exchanger?" box under the dash gets nice and hot, but that air doesnt seem to make it out the vents. -desperate

 

Not sure what you mean by "recalibrating the climate control." Have you performed diagnostics on your control head unit?

 

The Haynes manual sets out the diagnostic routines. If you are planning on doing any car repair, you should get one for your model. It will be money well spent.
