K it worked like a month ago when i used car, but when used it last week was blowing cold air, its not fogging the windows or anything on defrost so i dont think its the heater core, was low on coolant so i filled it...i think it got luke warm for a minute then went back to cold....when radio is off, i cant hear so kinda liquid moving around and making noise from behind dash on passenger side. im not sure if somethings clog or not? or maybe i just need new thermo? any one can help? car reaches normal temp 2 right in middle
