I have a 90 240sx FB. Everything works on the heater controls execpt the push buttons. ie zone control, and the circulation control. They don't even light up. With winter coming this really sucks. Any help would be appreciated...

Same problem here. There is a little motor that is above the gas peddle under the steering column acess panel That is connected to the heater box. It has a brown wire connector to it. That is what controls where the air is devirted to. Mine is bad. All I do is switch it manually( pull or push the rod to where you want the air to come out). I havent replaced it yet & dont feel like it.
It isnt that hard to reach under neath the panel & switch it manually. Once you do it once, & get the feel for it . It isnt that bad. I havent even priced out a new switch for it.

hey, this is kind of related ... on my s14, the lights on the heater control DON'T light up. are they supposed to? the only things that light up are the fan speed controls and the slider for the temperature.

i've been lazy trying to find the problem
