My '07 recently developed a noise at start up in the passenger side rear panel which appears to be the rear AC. When the van is started with the rear AC on, what sounds to be a compressor, (almost like sticking something in a fan) will rattle and vibrate for about 30 seconds and then will quiet up and act normally until the next time the vehicle is shut off and re started. The van is under waranty still, but I'm just checking to see if anyone has had this issue before. I checked the TSB thread and didn't see anything mentioned. I'm pretty sure the rear AC compressor is about to puke..... Any suggestions?
