Engine warms up normally, so no problem with the thermostat. I checked the heater controls in the dash and the attachment of the cables to the heater body under the dash and everything seems normal.
Any idea what would be blocking the flow of water through the heater core? If I understand it right, the temperature of water to the heater is always whatever the engine water temp is, and the hot air comes from air being redirected through the heater core instead of bypassing it.
Thanks in advance to all you gurus out there.
