heater not moving air
Ok I have an interesting problem. My 90 xj has been under water a few times and I think I have some silt or dirt in the fins on the heater core. The blower works fine when its on the cold air side (no a/c) but when I put it on heat it moves maybe 50% of the air. Anyone know a way to clean out the core and or ducts without removing the heater core?
