I have hot air heat on recirulate put only cool air on floor, by-leavel and defrost heat setings

Guess again?
for sure dampers are not right
only why remains.
recirc door is vacuum. servo ops
but not mode
have you tried the mode door recalibration method yet?
blend door

Manual calibration of the A/C-heater control should be performed if the blend door actuator is not functioning properly, or if the temperature of the conditioned air is too warm with the temperature control in the full cold position or too cool with the temperature control in the full hot position.

This calibration procedure can only be started within the first ten seconds after the ignition switch has been turned from the OFF position to the ON position. Make sure that the battery is fully charged prior to beginning the calibration procedure.
NOTE The length of the pause made at each end of the temperature control rotation (sweep) is important. 5 seconds) or too long (greater than 1.5 seconds).

1. With the ignition switch in the OFF position, move the temperature control to its middle (12 o'clock) position.
2. Turn the ignition switch to the ON position (do not start the engine).
3. Within 10 seconds of turning the ignition switch from the OFF to the ON position, perform the following rotations (sweeps) of the temperature control.
   • From the 12 o'clock position, rotate the temperature control counter-clockwise to the full cold position. Pause one second.
   • Rotate the control clockwise to the full hot position. Pause one second.
   • Rotate the control counter-clockwise to the full cold position. Pause one second.
   • Rotate the control clockwise to the full hot position. Pause one second.
   • Rotate the control counter-clockwise to the full cold position.
4. end

Blend door actuators could be bad, or vacuum leak in hoses.
