HI my 2002 MonteCarlo SS 3.8L is randomly dieing, We have replaced the battery,alternator, crank sensor, MAF sensor, battery, key switch, and probably more and it still dies.

What is your question?

When it dies the battery light will come on. the electronics like air and radio stays on, but the air goes from really hot to cold immediately when it dies.

How long has your 2002 Chevrolet Monte Carlo had this problem?

1 1/2 years
