I have a 1994 Ford aerostar. I bought it used in the winter. The AC works,
but no matter where I put the selector switch, the air comes from the
defroster vents by the windsheild and the heater vents by the floor. It has
to be in the switch or there is a door in the ducting that directs the air
through one set of ducts or another. I am used to working on old GM trucks
and every time I think to try to figure out how to figure out How just to
get started I give up. I just need a starting point. The fan switch asembly
is in the middle of the dash and there doesn't seem to be any access. I
believe that un older Chevys the door that controls the airflow in the
ducting was controlled pnuematically.
The cruise control doesn't work and if I remember correctly it was
controlled by pnuematically as well. (on a Chevy). So I guess that the
relays that control both could be on the same fuse. I don't even know where
to find the fuse box.
I'm getting old and poor and the summer is coming on strong. I live in ABQ,
NM and it gets really hot here. I don't drive very much, but I do drive and
I would like very much to have my AC.
