911SC temp control/rheostat
 

Replacing my switch but no marking on old one. Anyone know where the green/white wire goes to on new style switch - terminal 3 or 4?

You say you are replacing the temp control rheostat? Is this the one between the seats or in the dash?
If between the seats, where did you find the part? New style?

The one in the floor console by the fan speed switch - our sponsor -

It's just a little different but works - issue is there are no labeled terminals on old one and new one has 3 or 4. I tried switching the wires, but bc my AC all has to be replaced I can't tell if it is colder for warmer.

I see now....... this is the a/c temp control switch.
I was hoping you had found a source for the auto heat control rheostat in the console between the seats.
Good luck!
