I am new to this forum so my apologies if I say anything I am not suppose to. I have a 2013 GTS launch edition with 34XXX miles and having problems. I came home after a drive and I pulled in garage and turned car off. Walked away from car and ac fan stayed on. I have then have 8 volts from negative on battery to negative cable(so a short). I have pulled all computers and modules and have pulled every fuse and every relay......still have a short. Then if I pull the fan plug out or the resistor, there is no short. Put new fan blower and resistor. Did not fix problem. I am at a loss. I don’t know why I still have power going to just the fan motor. I can even control it by turning knob. But nothing else works. I have even unbolted starter and alternator wires. Still short. Also is stuck in race mode(think this is separate problem but happened at same time.) Put 2 new batteries. Any help I would greatly appreciate. I am not suffering as I still have my 2000 GTS to drive. I am mechanically incline and would

Did you ever get this fixed?
That's an odd one. Since most of the modern car systems are CAN based nowadays I wonder if it's a bad BCM or something. I've had some weird gremlins with my 04, but finally figured it out. The turn signal stalk combo switch had worn down and was allowing the fog light switch to close, but that switch is never meant to close unless the light circuit is also on. When it would happen it would like my fog lights, but turn out the A/C compressor light on my HVAC control panel. Made no sense that the two would be connected, but figured it was just a logic condition the computer was never programmed for.
Long story short, maybe there's a faulty switch or something in the system that is allowing the BCM to keep the fan motor on.
