They Just Said It Was The Actuator. I Don't Know Exactly What They Did. A Friend Of Mine Who Is A Mechanic Of 45+ Years Is Going To Check It Out, That Is Why I Wanted Help On What Else It Could Possibly Be. I Will Tell Him About The Recalibration And The Heater Core (which He Probably Knows Already). I Just Had Wondered Why Some People Said They Could Get Out The Part Thru The Glove Box And The Dealer Says The Dash Has To Be Pulled?? Thanks For Your Help.
