I'm having trouble starting my Jeep Grand Cherokee because the lights keep flashing. Can you help me figure out what's wrong?

If your Jeep Grand Cherokee is experiencing issues with the alternator, there are several noticeable signs. The first indicator is a dead battery. While a dead battery does not always indicate a faulty alternator, a common reason for a dead battery is indeed a bad alternator. If the battery has not completely died, you may observe dim or malfunctioning instrument panel with flickering and noise due to fluctuating power supply. Replacing the alternator typically costs between $300 to $500, inclusive of parts and labor. Though it may seem costly, it is essential to address the issue promptly to avoid further damage. Delaying the replacement may result in a battery failure in a few weeks, incurring an additional cost of around $100. If you opt to replace the alternator yourself, you will need to unbolt the clamps and remove it, which is conveniently located upfront and easily accessible.
