First off, i have no A/C.
When driving, my car usually tends to blow very hot air even when the fan is off, slider is on cold, and the circulation is closed. More than the usual slight ventilation. It's fairly cold outside, turning the outside circulation doesn't pull in outside air, it just blows really hot air. On warm days where i want to bring in normal air, it feels like it's pulling air off the heater core. It sucks
I'm fairly sure it has to do with vacuum since the entire car is run off it.
Where should i start to look? Engine bay or under the dash? Any specific lines i could be concerned with?
Also, what does the little "floor" switch do under the driver side steering column, switching it does nothing noticable.
