The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

    I took the Blazer in to the shop and 860 dollars later I got the car back, that was 7 months ago. Now I am having the leaking problems again, but not in the inside of the car. Its leaking on the outside under where the heater core is placed. I am getting tired of this nickle and dimming of a rig!!!
