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!!!
