On a 1996 model you probably have vac actuators that control air flow. Look under the dash and you may be able to see the actuator that controls flow to the defrost and vents. There would be another one for temp control.

If you have no overdrive at all, and virtually no third, then it's time for an overhaul. The 3-4 clutches have failed, a common problem in this trans since 1981. Yes, 1981. Your trans is a 4L60-E that is computer controlled. In 1981 it was called a THM700-R4, and was hydraulically controlled. The input clutch drum is basically the same as it was in 1981, and the 3-4 clutches are prone to failure, usually around 130,000 to 150,000 kms (75,000 to 90,000 miles).

Dash vents will not blow air


It may be the mode actuator. Have you heard any clicking or other strange noise ? Under the drivers rear seat, in a plastic box is a fuse panel. Remove the two retainers, and the cover. Remove the HVAC or A/C fuse for a minute or two. Reinstall the fuse and this will make the A/C system relearn. Whwn you put the fuses back do not touch the A/C controls. Start the truck and leave it run for two or three minutes. Then try to change the vent from floor to vent and defrost. If this does not work you will need a mode motor. Good Luck

Vacuum diagram 1992 ford taurus


Well as far as knowing exactly which hose to put where i cant help. Other than tell you to buy a chiltons manual at advance auto. Now there is a box in the passenger side floor under the dash of your taurus. this box is actually where the flipper is that switches from floor, to vents, and of course your defroster. So you can reach up there manually and switch yours to defrost. Just turn your heater on and(blower motor) then look for the black box should be like one foot by 1 foot. There will be a little siver selector switch on the side of this box. Just flip this switch by hand and you will make your hot air go up to your defroster, also while you are under there, look for loose vacuum hoses, this is normally cause by children hitting these hoses with their feet and disconnecting them. So i am sure now that you know where to actually look you can fix this problem. Hope this helps ya
