If you have control of the climate control on the steering wheel as well it may point to a wire getting pinched or grounded in the steering column. If you turn the wheel all the way left or right does it shut the car off too? My other ideas are perhaps a failed body control module or if all those accessories share the same relay there may be higher than normal resistance causing a spike. Good Luck!
I have a Cadillac Deville DHS 2001. Whenever I used the signal light, blow the horn, or turn the AC, the car shuts completely off. Someone please help
