I had low cabin heat for a period of time and suddenly went to no heat condition at the beginning of this week. Next day the P2457 engine code was thrown.
Is there a way to definitively tell if it’s the heater core or a stuck open thermostat?
Thanks!
If I end up needing a core, does anyone have a good source for a new one?
