I am seeking some ideas here. My car has been an angel for quite some time but has decided to change that today. Upon arriving in my driveway, I put car in park and cut the heat on. I was just letting my kids out before heading back to my store. After turning heat on, the car shuts off with no warning. So first attempt at starting it back, ended with engine attempting to start. It got as far as turning over then nothing. Since that attempt any other efforts have been a big negative. I have no cluster action. Lights are dark, gauges don't work. No sounds at all. My headlights work and battery is fluctuating in the mid 12 volt range. Any ideas? Car is 95 3.4 v6 auto.

 

check your fuses ,an relays is an idea
