Hi there. Sounds like you’ve got quite a few things going wrong with your Monte Carlo. Although most of those component are monitored by the ECU, this sounds more like an ECU power relay or other electrical system issue to me. The only way to find out for certain is to contact a local mechanic who can complete a full electrical system inspection to determine what’s causing the symptoms you’re describing. If you’d like, a certified technician from YourMechanic will be able to provide this diagnosis at your home or place of business at the connivence of your schedule.
