I have a 1990 eunos automatic that has a red light in the dash, marked "heat", that glows after medium to hard driving. What does this indicate? Should I be worried? Many thanks

its the automatic box fluid temperature warning, make sure the auto-box fluid is upto the full mark, it doesn't indicate a problem just that the box is getting hotter than is best for it and advising you to take it easy.

Dashboard brake light stays on, 1990 Suburban

Most likely. Usually what happens to mine, is the wires to the sensors get broken from stones hitting them. i splice them back together and they are good for a while. Or the sensors get dirty.
