Is there any circumstance in which the air conditioner . . .
I mentioned a few days ago that muy air conditioner shut down three times while driving home one day. The service department thought it might be that the temp sensor is defective. However, I did not think the air ever actually is supposed to stop completely in the auto mode. Am I wrong?

yeah if it is in "auto" mode once the cabin temp is reached the AC shuts off until the cabin temp reaches 2 degrees above the preset temp.
Chrono, when you say your A/C stops, do you mean the "auto" light goes out and the fan stops completely? Or is it like you manually pressed "auto" to go into manual mode and the system is using the current knob positions? If your fan speed knob is currently set low (it doesn't matter in auto), you might want to set it higher so if the auto light goes out again, you can know if the fan is still running. Do you get what I mean?
Sorry, but what are you talking about? The A/C never "shuts off" by itself. The C230/240 system only shuts off when you turn the fan speed knob to the "zero" position.
ChronoPassion has a C230, not a C240/320. Mine works like this all the time, once the temp is reaches the AC is dramatically reduced, down to the lowest level possible, sometimes you can't tell it isnt still until you put your hand in front of a vent.
Chrono is saying his light goes out: "light goes off (and the air flow itself also stops) when in the auto mode".
I've never seen the "Auto" light go out by itself. Once the temperature is reached, the fan slows down and the output temperature is moderated as MarkL said.
BTW: I've found that Auto can still be used even if the fan knob is at zero. Just press the Auto button again and it'll kick on. Weird....

As I mentioned (to be clear) both the auto light turns off and the air completely stops abruptly. So, I do not think it is a temperature sensor since the auto air should still be running regardless (at whatever low level) and the light should not ever turn off, as far as I can tell.
Thanks,

From what I remember it's a safety measure. It shuts down if there's low coolant (whatever that ozone-friendly stuff is..).
Don't quote me on that though.
......But the A/C sure does a dxxn good job in keeping me coool.
I have the standard A/C controls in my coupe.. it's the most confusing set of controls in any car that I've owned. My friend's BMW's A/C controls are just as confusing. (and I am an engineer)

! What gives? I think it's pretty intuitive. Two temp knobs for driver and passenger. One knob for air direction, one knob for fan speed. Hmmm. "Auto" controls both. In manual, both knobs become "activated" and do what they're set for. Then, the extra "ECON" button to control the compressor. I don't know how it could be much simpler unless they didn't let you control the thing manually. Do you like the type where you keep pressing "mode" to get to the vent selection you like? And the type of fan control, like on the C320, where you have to keep pressing it over and over until it gets where you want? IMO, the knobs actually make it easier to get what you want quickly.I agree w/ you about the cooling capacity -- it's been working great here on the 97-100 degree days. Takes 3-4 minutes to cool down and keeps on going.
In manual, you set where you want the air to blow.
The auto fan cools off the car very fast, and keeps it at a comfortable temp.
MarkL, maybe the knob is a little quicker for changing the fan speed, but I don't have any complaints about using the button. Of course, I use automatic most of the time, so I rarely have to use the button.
Maybe it's different in the C320 (I know we have a different unit), but we can have the fan on auto and still control the vent selection. I nomally manually choose the vent so that I am getting the amount of air that I want blowing towards my face.
