My 2010 V6 stick has begun stalling constantly - like the ignition key was switched off kind of stalling - whenever any function in the climate control is turned on. Blower on low, A/C on or off, makes no difference - the engines stalls. If I turn it off, it starts and runs fine. It did this a year ago 2 times, but could not get it to repeat so did not go to dealer. Now it has 39K on it - NATURALLY - and it does it constantly. I can turn the lights on no problem, but not my aftermarket fog lights (which I have tried disconnecting to isolate the problem but it still stalls with them disconnected). It's getting cold in MI. Need the heater to run. I pulled DTC's P0690, P1233, P201-P206. Any input?
