The EV is about $119 from the dealer. Sparkplugs.com sells the actual Denso part; same as the dealer for $36.05. The problem is, so I am told, the entire dash has to come off to change it, which by the service book is 7 hours of labor.

Can someone tell me what the "air inlet door servomotor circuit" is? When I run the climate control diagnostics, I am getting a code 42, and that's what it's referring to.
In thinking back through all of this, the problems started on the day my hood latch cable stuck. I sprayed some WD-40 on the hood latch under the hood to try to lube things up a bit. Within a few days, I started hearing this tapping noise (like a baseball card in bicycle spokes), and with two weeks, my a/c stopped working at stoplights. Interestingly, it still works on the highway. Is it possible that this "air inlet door" got WD-40 on it and is stuck partially shut and the compressor is only getting enough air at highway speeds?
I'm all ears. Please let me know what you think. Thanks.

So this helps open some "doors" here, pardon the pun, into what may be happening. Sounds like you have a problem with your fresh air/recirculation door motor.
So let me start with saying that I've yet to see this problem on this car personally yet.
The code is telling you that there is a problem in the servo or motor ckt for the air inlet door. Which could mean a couple of things.
1. Electrical
2. Servo/motor malfunction
3. HVAC case/box issues. (you don't want this)
Here's what happens on alot of cars. There is a HVAC housing or case, (made of plastic) that houses the evaporator, the heater core, the blower motor, and all of the doors and pathways that allow you to have air at all of the specific vents throughout the vehicle. The doors are also plastic hinged into the case by plastic. With all of the movement these parts do sometimes one of the three plastic pieces fails, either the door itself or the box breaks where the door attaches. The motor then is actuated and basically over rotates and can set various codes including what your seeing.
Remember I have never fixed a GS with this problem. But from what your describing it sounds very close fit if not leading you in the right direction...

I called the dealer first thing this morning to tell them about the diagnostic code, and spoke to my service advisor who promised she would talk to the technician and get back to me. Unfortunately, I didn't get a call back.
Anyway, thanks for all of your help. I'll keep this thread posted with any developments. Please let me know if you can think of anything else.
