Toyota Repair: Heater Core?, toyota factory, heater core

Question
Hi Ted,

I own a 1992 Previa AWD LE that strongly appears to have a failed heater core -- AC will run, it produces a fog from the vents which smells like anti-freeze, and attempting to defrost the windows produces even more fog on the windows ...!  If this sounds right to you, can you give me any guidance on how to replace the heater core -- the Chilton's I have is no help.  Or, a good source for information on how to do so?  My thanks in advance.


Answer
The toyota factory repair manual doesn't seem to help either, I could not find any procedure for removing the heater core, I believe it's located somewhere in the middle under the dash and most of the dash and the console has to be removed to get to it, also the a/c evaporator has to come out.
