Sorry for the caps but some of this was already typed.

HERE IT GOES.

THE BLOWER ON THE HEATER, I REPLACED THE SWITCH AND HAVE ALL 3 SPEEDS SO ALL IS GOOD THERE.

I OILED THE CABLES AND ALL IS GOOD WITH ALL THE LEVERS,

THE PROBLEM LIES IN THE AIR COMING OUT. FOR INSTANCE I PUT IN ON HEAT AT FEET ONLY AND A LITTLE WARM AIR COMES OUT THE FEET AND A LOT OF COOL AIR COMES OUT THE UPPER VENTS
 ( AND THEY SHOULD BE OFF ) IF I PUT IT ON DEFROST AND HEAT AT FEET SAME THING AND NO AIR AT DEFROST.

I PUT IT AT DEFROST AND NO AIR AT DEFROST AND ALL AIR AT UPPER VENTS.

BASICALLY MOST OR ALL AIR IS DIRECTED TO THE UPPER VENTS.
( THE SAMMI HAS NO HOT AIR SELECTION FOR UPPER VENTS )

SO WHAT YOU THINK?

Also I have drilled a hole and vacuumed a lot of debris out of the heater box, and the heater was much better, but still have the air coming out the top.
