It ended up being one of my comfort access door handles. It blew the fuse, which unfortunately is the same fuse for all those lights. Check your fuse diagram. Mine was a F2 5amp in the passenger fuse box. I unplugged all of my comfort access harnesses on the handles and replaced the fuse. After erasing all the codes, it did not happen again. I had to plug each one back one at a time to see which handle was giving me problems. Be sure to have extra fuses as it will blow \nagain once the problematic handle is plugged in again. Since your driver door doesn&rsquo;t work, I would start there.<\/p>\n                        <div class=\"cta-btn\">\n                            <a href=\"https:\/\/www.carparts.com\/blog\/what-does-it-mean-when-all-dashboard-lights-are-on\/#commentform\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Jump to Discussions\">Jump to Discussions<\/a>\n                        <\/div>\n                    <\/div>\n                <\/div>\n            <\/div>\n\n        <\/div>\n    <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What Should You Do When All Dashboard Lights Turn On?<\/h2>\n\n\n\n<p>Dash warning symbols are also referred to as telltale lights because they alert the driver of a situation or fault. Multiple illuminated warning lights are definitely a cause for concern, but that doesn&rsquo;t mean your vehicle will suddenly stop working as soon as they show up. However, it&rsquo;s advisable to take your vehicle to the nearest auto repair shop as soon as possible. The longer you put off having your car checked, the more likely it is that it&rsquo;ll develop more problems, which can lead to an expensive repair bill.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Get an Alternator for Your Ride<\/h2>\n\n\n\n<p>A bad alternator can lead to electric problems, causing all the dashboard warning lights to come on.
