Have U Checked The Heater Core?

Also, Have U Ever Taken Off The Thermostat? Sometimes People Take Them Off, Maybe The Previous Owner Took It Off And It Just Takes Hours For The Heater To Heat.

I'm not sure if your model has one but some have a small vacum (somtimes cable) operated tap that will prevent the hot water running through the heater core when cold is selected. These are prone to rusting and staying either open or closed. They are usually in the engine bay near the firewall on the hose going to the core.

It works again, there was a stupid wire misplaced. Sorry for the inconvinience.
