Heater Core

If I had the heater core box out of the car, I'd replace the core.  You can
get one for under $60 at Autohause.az.


If I remember correctly from when I replaced all the wiring in my driver
doorjamb, there's a bunch of red/XXX wires associated with window
operations.  There are Red/Blue, Red/Black, Red/Brown, Red/White, Black/Red
and some assorted yellow wires too.  

You describe symptoms of a breaking wire.  Before I did my wiring, I could
only operate windows and the sunroof with the driver door partway ajar.
All the way open or all the way closed and nothing worked.   When I cut
apart the wiring bundle, almost all the wires had failing insulation.  

I just ran new wires for everything, connecting inside the door and inside
the cabin.  Not too bad a job if you set your mind to it.  I did it with
the car up on jackstands so I could sit close to the opening.  Kneeling or
bending over to do this job would be a real pain.  Now that I have a hoist,
I'd do it standing with the car raised to a comfortable height.
