AC PROBLEM:
Just finished a 200 mile mostly interstate trip.
At about 120 mi into the trip the AC stopped blowing cold air.
Still blowing, but just air, not cooled, as though the compressor was off, but the orange compressor light was on.
AC not in AUTO mode, both settings on 69, fan on med-low. 90 outside.
Tried different fan speeds, turned AC off/on a few times, no change.
Turned AC off about 7 min, then back on, no change.
SOLUTION:
Pulled off interstate into gas station, turned engine off and opened the door to make sure all electronics (radio) were off.
Started car, AC now blowing fine, cold, air.
No further problems.
I had similar problems with my '96 Sebring, about 4 or 5 times a year, it would not shift past 2nd gear. Solution was to pull over, stop and restart the engine, always worked. Also on that Sebring about 4 or 5 (different) times a year the speed control would not engage. Solution: pull over, stop and restart the engine, worked every time.
My guess is software bugs. Some unexpected, unprogrammed for, combination of variables causes the code to go somewhere it can't get out of, like say turning off the compressor momemtarily and not turning it back on. Stopping the engine and restarting restarts the software from scratch clearing the bug condition.
I never took the old Sebring in to be fixed, in my experience, if you can't reproduce the problem on demand, then they can't find or fix it, although they will certainly pretend to, and charge you accordingly. When you bring it in for the same problem a few months later, they will find a few more things to change/fix and charge you again.
If the hemi does this again though I'll bring it in, but with low expectations.
MILEAGE:
For the 200 mile trip. 24 mpg exactly. Car now has about 650 miles on it.
Interstate: 160 mi at 73 mph.
35/45/55: 40 mi with some stop lights and some cruise control.

For the same 200 mi. trip in the other direction 2 days earlier it got 22.5 mpg
No headwinds/tailwinds either way, exact same route reversed. Hmmm.

Since your a/c wan't working you got better gas mileage. A/C really effects gas mileage like 4-7 mpg depends on how fast you are driving. The people that adviertise 27 + mpg must do it w/a/c off but never say that in their posts.

I got 27 with the cruise set at 70, a/c on, fully loaded trunk. Dropped to 22-25 once I got in the mountains, all highway driving, 600 miles on the car at the time. Most recently, I got 25 with the a/c on, no cruise, 75-85mph all flat highway,1600 miles on the car. Check the milage thread for more details.

M$ wrote the cars OS

Sure sounds like the cars operating systems where writen by Microsoft. Somethings not working you re-boot and then it works again, for awhile anyways. ;)

I almost wish it was written by MS - just think how easy it would be to hack!;)

The BSOD attachment is for a Magnum, but you get the idea.
Scary to think how much these new cars depend on software/hardware.

check to see if all fuses in trunk and under the hood are seated properly.

Has anyone actually had the dealer trace this problem to a definite "computer" glitch.
For my problem I find it hard to believe that a mechanical problem like a loose harness or fuse would magically, mechanically, re-connect when turning the engine off/on.

My engine was only off for 10 seconds, I don't believe an "iced up" problem could go away in a snap. Also did not have any "musty" smell you usually get with an icing up problem, also I believe the air does not come out as forcefully when iced up, as I recall from the distant past.
I did today go by the dealership just to have them look under the hood and see if they could check the compressor wiring harness at least. He didn't know how to open the hood!!!
Do you think they know where the wiring harness is?? In all fairness it wasn't a technician, it was a service "manager". Didn't want to turn if over to them for a day or so, just said I'd watch it and see if it happens again.

If it's a software bug, then many of us probably have this problem and it just hasn't happened yet. I would expect a computer update in the future would address it possibly.
