It was a cold and snowy day in the Chicago region.... ok my wife's 06 TB wouldn't blow warm air on her feet - the dealer diagnosed it as a problem with the 'Blend Door Actuator'- we bought this 3 months ago and bought the extended warranty- guess what isn't covered...
enough of the rant - i am looking for a decent explanation on how to get at this blend door actuator. the TB has dual climate control and works well otherwise.
total estimate for this repair is almost $600 (part cost $80.19)- which I don't have right now - and would rather save anyway.
