Temperature Blend Door Actuator
Our 2008 Taurus SEL with 150,000 miles is making a thump, thump, thump noise coming from the dash during initial starting - suspect that this is coming from the air handling actuator. Suspect that this is a motor driven actuator -- or could the thumping sound be coming from the damper -- is ther a spring to dampen the damper? or vacuume line to control?
Suggestions on how to trouble shoot and how to access: we have experience with heater issues - had to rework the heater system in our 1999 with 306,000 miles - vulcan engine still running great.
