I'll use a VARWATCHER to see if the pitot heat does indeed come on.  It will probably be tomorrow, however. 

First, I read the code backwards.  Any combination of either switch turned on will enable pitot heat.  I looked at it with a VARWATCHER and when either switch is activated to any position other than "off"  the simulator pitot heat does turn on.  I have no idea what the problem could be.  I have never heard of icing in the sim if pitot heat is actually on.

I've turned on both left and right switches. Additionally, at least on my model, each switch (left/right) only has two positions: OFF, or Pitot/Stall.

Again, I've utilized all deicing / heat switches in the aircraft, and just confirmed again moments ago that the pitot probes still ice over, resulting in airspeed indication loss.

Something is goofy here.  The pitot switches have three positions in the Carenado Cheyenne III.  OFF, PITOT, and PITOT/STALL.  Be sure you are using both right and left clicks on the switches to get the different positions.  That being said, my testing shows that the pitot heat does indeed come on.  I have the latest version of the Cheyenne III and P3Dv4.1.   

I flew in cold and wet conditions with the pitot heat off.  The pitot tubes iced up.  I turned the pitot heat on and within 30 seconds airspeed indication returned.  It seems to be working for me.  Make sure you haven't deleted the pitot heat line from the aircraft.cfg file.

Sorry for the delayed response. Just tried my version again of Version 1.1 of the Cheyenne III and my switches only have two positions: OFF or PITOT/STALL. I have tried left clicking, right clicking, middle mouse button clicking, scrolling, etc. When the switch is in the position of PITOT/STALL, my tubes still ice up in icing conditions when using software such as Activesky in real-world conditions, as well as with pre-built P3Dv4 themes.

Additionally, Carenado has acknowledged the issue to me in email and said that they will look at patching it in a future update (if that ever happens).

I have included a screenshot of my switches in the link below as an illustrative example. When in PITOT/STALL mode, the test lights on the left side wall of the cockpit light up when pressed indicating that there should be power for heating purposes, but again, still have problems with ice.

Bizzare!  Here's my screenshot of the same thing.  I think we have entered the Twilight Zone...........

... so much for Carenado's version control ...

I did some additional snooping following a reinstall.

It looks like the LITE version of the aircraft has only a two position switch (alongside all problems with the pitot heat) as I outlined with my previous screenshot. The normal/full version of the aircraft has the three position switch and so far it does seem to work correctly. How frustrating. I guess it's the full version for me!

We're still in the Twilight Zone.  My screenshot was of my LITE version.  Both of my versions show the 3 position pitot heat switches and my testing was on the LITE version.  Just for another data point......I bought mine directly from Carenado. 

Everybody has downloaded and is using v1.1? 

At least in FSX both, the lite and the standard version, have the 3 position switches.

The different avionics options install different model files, as well.  There are potentially 6 different model files out there, i.e. lite/full versions for the standard, GNS, and GTN.  This came into play with the AC690 where they had panel lighting bugs in 2 of the 6 model files. 

I'm struggling with incoherent feedback between button settings and the annunciator. For instance this, where setting bleed on shows it as being off..

For the left engine, setting bleed air produces no reaction on the annunciators at all. 

Purchased and downloaded today and I have experienced a freeze up in pitot tube even with heat on as I was climbing through cloud and also, even though my right bleed air was on as well as left I had a warning for it on the annunciator panel.  Has anyone else seen this?

Apart from these two issues I love this aircraft.

In my P3D Cheyenne III I just leave pitot/stall heat in off position as well as right engine bleed air.
No freezing pitot tubes nor the annunciator panel light bleed air off.
