2011 superduty no A/C
I'm posting this here because I am told the systems are different on the diesel models thatn gas models of the 2011 SD.
I have a less than 2 month old 2011 crew cab. A couple weeks ago the left rear turn lamp and brake lamp quit working like a burned out bulb. The dealer figured out that it was not a bulb, but rather, a body control module.
When I picked the truck up from that repair, it was warm out so I turned up the A/C. Surprise surprise, no cold air.
Back to the dealer who could not figure anything out. A week or two later, they replaced a cab sensor and that didn't fix it either.
Now (two days later) they are communicating with the Ford engineering dept and have come to no conclusion. They say they think it may be a power train control module, but they aren't sure.
The seat coolers work fine. The compressor and fan work fine if you jumper to it, but something is evidently preventing the command signal from turning on the Compressor.
Has anyone else had a similar issue?
I am getting quite weary with dealing with their ineptitude and am seriously considering making use of my state's lemon law.
Please help if you can.

They originally said they thought that and that the engineers said they had experienced issues with them, but as of this morning, I'm told that the engineers are saying that the BCM doesn't control that, but rather the PCM does.
Thanx for the input!

I don't think that the other dealers are going to be too anxious to do difficult warranty on a truck that I bought somewhere else. Besides, even the Ford engineers can't seem to figure out what is wrong.

they bill out the warranty work the same at any dealer. It doesn't matter where the truck was purchased.
I'm definitely not trying to argue, but I can't wrap my head around the ford engineers not being able to figure it out. This isn't *that* complex... a couple hours spent probing around and testing should yield a pretty straightforward result. I'd follow rick's advice and find another dealer, STAT

The service writer has shown me all the printouts of the communication with th engineers, and evidently the pin tests and everything else has not yielded any answers.
I also need a vehicle during the day for work, and I don't think that another dealer would furnish me a free rental.
Do you think the service writer has phonied all this stuff up?
I'm not trying to argue either, just sort it all out.

I agree with rickatic.
A good tech with a computer, multi meter, and wiring diagram, should be able to pinpoint the problem in a few hours at most. Being in the commercial HVAC field we have to troubleshoot systems waymore complex than the ones on a vehical. Sad to say not all techs are good at troubleshooting, in all fields, not just automotive. JMO

Its back with the dealer today. Evidently the biggest problem is the lack of electronic flow charts due to the fact that it is a 2011 vehicle.
Today they are supposed to run some tests to determine if the issue is the PCM.

Update:
After 4 or 5 attempts to fix it and a conference with the owner of the dealership, a Ford field engineer was called in. He said that it was a software issue with the BCM, installed a new program, and voila! Now I have A/C.
However, now I am getting poorer mileage even when the a/c isn't running , and the gear selection display has disappeared from my dash display.
I'll take the A/C though!

we had one that had no commuacation with the hvac controller, a bunch of src codes annd trailer light concerns. turned out to have burnt the main dash harness up. it was not to far from behind the radio/ havac controllers. I think it had soemthing to do with the trailer break controller or the guys trailer that caused the issue
