Why is it when you turn on the fan switch the head lights go out on my 1997 gran prix?
When you turn on the fan switch in your 1997 Grand Prix and the headlights go out, it may indicate a problem with the electrical system, such as a faulty ground connection or a weak battery. This can cause voltage fluctuations that affect multiple circuits. Additionally, there might be a short circuit or an issue with the ignition switch or wiring that needs to be inspected. It's advisable to check the vehicle's electrical connections and components to diagnose the issue.

The fan draws more current than your headlights. This causes greater load on the electrical system meaning there is less power to go around and run everything. If the dimming is greater than what you consider normal, it's possible that the alternator is weak and not supplying enough juice.

Why would 1997 venture motor stop when Ipush brakes at stop sign?
You probably have a bad alternator and a weak battery. I know it sounds strange, but I had the same thing on my 1996 Pontiac Grand Prix. The reason is, there is a big drain on your electrical system when you apply the brakes, ie: taillights, anti-lock system, etc. So, the car stalls, and in my case wouldn't restart. At the least, go to auto zone and have it tested....you'll be surprised.
