    you will need to replace the entire heater control head assembly...or perhaps you can stop by your local wrecking yard and swipe of knob off something there and put it on yours...good luck

Is it just the knob that broke or the whole thing
you can buy just the knob
if it is the whole thing then you will need to replace the HEATER CONTROL HEAD
hope this was helpful

Defrorstores stay on ,try to change to floor, ac, heat vent ,deforstores still on 1995 thunderbird lx blower motor works great.


Some cars use vacuum from the engine to open and close the doors that direct the air to different positions. It is possible that the vacuum line to the controls is cracked or disconnected.

What part controls switching air/heat from defrost to bi-level to floor & where is it located?


In the attached drawing, Part 32 moves Part 26 to direct the air flow to the desired locations. It uses vacuum to operate. The actuator may be bad or the vacuum hose my have come loose when the heater core was changed. With the car running but the blower off stick your head up under the dash on the passenger side and see if you hear a hissing sound. If so it's probably just a vacuum hose come off.

Air only comes out defrost in all settings


I just fixed mine. The lever that opens and closes a door that directs the air flow to the defroster was broken. To be more specific, the plastic lever the actuator attaches to was broken. The actuator and the vacuum system were operating properly. It is simple to see but hard to get to. Remove the glove box and look up and to the left for a silver vacuum controlled actuator. I was able to fabricate another lever and attach it to what was left of the OEM lever.

The air conditioning does not blow through front vents but through windshield vents, what is the problem?


This is a common problem on all Astro/Safari vans. The problem is a leak in the vaccum lines that control the vaccum switch responsible for changing air direction from the defrosters, dash vents, floor vents..etc.
Many of the problems that plaque the Astro/Sarfari vans and many other "Mini-Vans" is the build up of excess heat in the engine compartment. It\'s a tight place to put a V6-4.3 Vortec engine and the heat generated bounces back and cooks everything on the engine (coils, modules, sensors, wiring, and of course plastic vaccum hoses). No need to mess with your switches or anything behind the dash -- replace those thin plastic vaccum hoses to operate the vaccum switch (located just below the A/C canisters, to the right of the heater/ac blower housing) and your dash switches will magically send heated or cooled air where you want it.

The selector knob for the heat and air unit in my Sentra ( the one that directs air from the dash to the floor or defrost) turns but it doesnt change the direction of the air flo


This is usually caused by the selector switch being bad on the car. You will need to change the switch for it to work again.

My '99 century's heater/air conditioner will not switch settings(def.,floor, vent, etc) it will change speeds and temps only. it blows a little from the defrost a little from the vents and a little from...


sounds like there is a blockage in the heater ducts or the doors that open & close to direct the air are stuck or broken. maybe a bad blend door actuator

Heat selector switch?


The switch might be bad, but if it's vacuum operated, there is a vacuum operated diaphram
under the dashboard that operates a door to close
the air from defrost to direct it to floor or mix.It's possible there might might be an air leak.
