    looks like I will have to replace the heater core in my 79 Ranchero. Can anyone tell me if the core is the same for A/C and non A/C. Mine does not have A/C.
    Thanks Gerry

    That's gonna suck if I have to replace mine. I'm lucky so far. *raps knuckles on noggin* I wonder if you can get a cheaper replacement (likely of aluminum rather than brass, I'd imagine) from any of the regular parts houses?

    The 'cheaper replacement' is called a jacket.

    I know this because I've been there. Defrost is opening the hood and running the engine at 2000 RPM.

    Great idea! I need to do that on my LTD. Heater core doesn't really have anything left of it

    My brother has the Harbor Freight version, which barely does anything. Waste of $14 or so GrandMarqBuxx.

    I use the Rain-X anti fog cleaner on the interior glass. It works rather well.
    My defroster 'works', but is not very effective.

    It works well at Sea Level, but going over Snoqualmie Pass late last November (3089' on I-90), the windows still totally fogged with no working heater. That was a bit hair-raising with my brother driving, and Dad and I doing our level best to see where we were going and who was around us in his '97 Grand Marq. On my next pay day, I bought the needed heater core and got it installed.
