As the cold weather is gaining a foot hold here in St. Louis, I need the heated in my 1986 SL. The blower and the auto temp control works, however, it only blows out from the two outside dash vents. Does not blow thru the middle dash or the floor vents.

Thanks in advance for and ideas on keeping warm this winder.
