This is the air conditioning evaporator for your 1993-95 Lightning. It is located under your dash and it's job is to pull heat from the air blowing into your car to produce cold air flow inside the cab. This can become cracked over time and may need to be replaced. This is a direct fit factory replacement for your SVT Lightning!
