    Heater Controls Not Working, Light Blinking.

    Getting no heating/cooling in the car. The blower/fan doesn't turn on when I select use the controls, A/C or not. In fact, when the A/C or even the rear deforst is turned on the corresponding button flashes every second or so. Anyone seen this before? Any ideas?

    Haven't seen it before, but you could start by checking fuses.

    The blinking light seems to indicate that the car knows something is wrong. Hence check fuses.

    If they're all good it might be time to break out the multimeter and go to town on your dash wiring.
