umm...check this first?
Based on the commentary, the detailed photos, and the link to a how-to-check-this site, I suspect that this may be a common area of failure AND "a lot easier to check/repair than the core".
Or I guess you could skip the easy fixes and dive right into the remove-the-innards-of-your-car-and-hope-that-the-$2000-repair-actually-fixes-your-problem stage. All on the recommendation from a guy who is "pretty sure" that the core is bad? Pretty sure? You have got to be kidding, right?
What you want to hear from a real mechanic is something like this: "Sir, we have eliminated every other possible item in the heating circuit including a, b, c, x, y, and z. Unfortunately, the only possible thing it can be at this point is the core. I guarantee it."
yeah i get what your saying, what had happened is he was just looking at it, he wasn't like going deep into it cause i just asked for some advice i wasn't paying him to tel me the prob.
but i am going to try and replace the heater control valve an see what happens there, if i do end up getting rid of it i found another 93 sc4 in houston that is really clean for $6k.
thanks so much to all of you
