If you leave your fan mode dial in any other position than off, or the stereo power, before you shut off your car if you have an 05/06 you will be draining the battery. My battery went dead a couple weeks into my first winter here only having the car less than a year.
Guy online told me to turn off any active modes the car can have on from the dash before turning the car off, wait a few seconds, then turn off the car.
I've never had a battery issue since, still going on that second battery I put in the car in February 2007. Erik

To All on this message board who have a 2005-2008 Mustang. I am currently sitting at the dealer having my alternator replaced after receiving the dreaded P0340 P0344 error codes. But while sitting here I also found that my lower engine cover was missing! Apparently the Dealer and other oil change places have a bad habit of removing this cover in order to get to the oil filter, and they either inadvertently forget to put it back or they intentionally forget to put it back because its a pain in the butt. That being said, I implore all of you to make sure you have your lower splash shield in place, otherwise you will continue to have your alternator fail due to dirt and water getting in it. If your engine compartment is showing signs of splash back or mud, you have probably had the lower engine cover removed by a lazy mechanic.
