Check the fuses.
what does it do
2001 monte sunroof will not close completely , where is the problem and how can i fix it.
Your heater core is likely bad
If your regular headlights wont turn on but only the brights for your Monte Carlo 07 then you're probably experiencing an outage in the light area. The fuse or the bulbs may also be the cause of the problem.
I have a 2003 Monte Carlo SS and the only time it turned off on me was when my radiator had broken and the car was over heating. Its turns off so it wont explode.
Try replacing your spak plugs. I had the same problem with my 85 Monte Carlo.
Transmission temp switch is most likely cause.
If the alternator is good then the battery is bad.
You would diagnose the problem and either fix it or scrap the vehicle.
Put gas in the tank and try again.
your instrument cluster is either corroded and needs to be cleaned, or the circuitry on it is fried.
the door striker needs adjusted along with possibly the latch mechanism.
