Umm... I kind of doubt it; the HVAC controller is pretty much interested in itself only, not issues with the engine or powertrain. Given the age of your car, it'* most likely trying to tell you that you're low on refrigerant, but in any case you'll want to just get the error code out of it and see what it says. (It'* not the same as a Check Engine light; it'* an error in the climate control system, not an engine control system.)
