smell antifreeze inside truck and windshield fogs up when heater is on..... on 1995 Ford F-150

I think its the heater core, is this correct??? I don't know much about repairing it, but is it a major and expensive repair job????

Asked by for the 1995 Ford F-150
yes and yes it is a few hundred to replace because the dash on most vehicles has to be removed to access heater core
