The trunk open warning light indicates when your trunk is not properly closed. If you are unable to close it, the latch may need to be fixed.
It sounds like the trunk courtesy switch has failed and allowing the light to stay on as if the trunk is open. This switch is usually built into the latch assembly. It can be tested for continuity with a digital volt/ohm meter to be sure that the switch is as fault. A broken wire can produce the same concern.

on a 1970 Lincoln mark iii Interior lights wont turn on and warning lights are very dim and doorlock button makes buzzer go on
ANSWER : Hi there. Although the electrical systems on older vehicles tend to be much simpler in design, in many cases, issues like you’ve described can be very tricky to trace. It could possibly be something as simple as an expose wire creating an electrical short or a faulty relay that is not completing an electrical circuit. I wish we can help you further, but the best advice I can offer is to have one of our mobile mechanics come to your location and complete an electrical problems inspection.

Automatic Trunk open/close feature not working but button lights up. I soldiered broken wires back together – reset?
ANSWER : Hello, thanks for writing in. Most of the time this is caused by a programming issue with the control module. It usually occurs if the module fails or if there is a loss of power. It can also occur if the batter is jumper improperly but most of the time you will have other issues also. If the battery was jumped correctly then I usually start by reprogramming the control module just to see if it will accept the programming. If it will not, then a new module will probably need to be installed and programmed to the vehicle. Not many places have the equipment to do this, so it is usually best left to the dealer where you got your car. I recommend having one of our certified automotive technicians from YourMechanic come to your home or office to inspect, diagnose, and repair the issue for you.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit. For more help with these electrical tests, contact our service department.

Dash, Tail/brake, dome, trunk, glovebox, and door lights won’t work, dash doing weird things.
ANSWER : Hi there. Sure would appear a lot is going on electrically all at once. This could be, a problem in the PDC (power distribution center). The PDC is typically located under the hood and contains numerous fuses and relays. I don’t believe any one fuse will resolve all of the electrical issues. There is a possibility, it is not a power supply issue. It may be, the result of a poor electrical ground common to the inoperative components. Proper circuit testing should be performed. This would confirm the cause of multiple electrical failures. I recommend having your vehicle’s electrical problems be diagnosed and repaired by a certified technician, such as one from YourMechanic.

Is it the trunk latch assembly or something else if you know the trunk has been closed , but the trunk open light in the instrumen
ANSWER : Hi Frank. This is a weird glitch that I’ve seen on some newer GM’s. In most cases it’s a faulty connection to the trunk lid sensor that will trigger the trunk warning light on the dash. However, I’ve also seen a situation where the sensor itself is slightly misaligned and creates this fault. This is one of those situations where unless they can replicate the symptom while trying to diagnose the problem, it’s difficult to pinpoint and resolve.

Dash lights show doors open and trunk only opens with key button
ANSWER : Sounds like the rear electronic control module (ECM) is failing. This prevents the determination if the rear doors are closed, and also controls all of the trunk electronics. You can try a used ECM, but the hardware number and the donor vehicle’s options need to the same as yours. Otherwise you will have to get yours coded at the dealer.
