spare time report:
i don't have a complete fsm for suzi. my vaugely useful chilton's mentions a/c, but refers most service to the professional........, so i have just started taking things apart.
i removed the blower motor and its carrier/ducting thing,and think i'm looking at the a/c "radiator"?
somewhere in there is the heater core, so i have to start being careful. i also found out where the mouse i found earlier had set up house- in the ducting.
my plan is to remove the a/c related stuff, clean the mouse spoor out and reassemble.
i'll bet the heater works better when i'm done.
