yep sure does. do you know for sure it's your heater core though? may want to check your heater hoses and see if they're even hot first instead of going through all that. also check your thermostat and see if you 1. have one and 2. if it's any good. there are a lot of things you can look for before trying to replace the core. easier things. but yes, it's behind the dash and i think it is where the radio and things are but not too sure. some are where the glovebox is but way behind it.
