I have tried everything I was able to Google up, but apparently have not gotten to the root of the issue yet. I'm hoping someone here will be able to steer me in a fruitful direction. I have never had a problem with heat in this vehicle before, except for having to replace the heater core 3 or 4 years ago. About a month ago, I turned on the defrost to knock the fog off my windshield, and no heat. So far I have tried the following: Checked the heater core supply hose... gets real hot; checked the heat control potentiometer... seems fine; checked the vacuum lines... found a leak in the one to the blower housing, repaired with vinyl tape - actuator appears to work, as do the other two vacuum actuators. Is there anything else under the dash or in the engine bay that could prevent me from geting heat? Thanks in advance, Bruce
