I've had a leak in my a/c for a while now, bad enough that I won't put in any more cans of refridge. I took it to Car-X and they couldn't find it (although they did replace one of the steel lines that didn't need replacement
). When I called they said it's possible that it's the evap core and that I should be able to see the dye but I'm not sure where to look. anyone know where I might see the dye?
