Turn signal and hazard lights are not working. 2000 Chevrolet Prizm

ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.

ANSWER : Hi there if the fuse for the turn signals and hazard warning lights is good, the flasher unit – same integrated unit services both functions – is likely bad, and should be replaced. I would recommend a turn signal/hazard warning flasher replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location and repair this problem.

ANSWER : I would first look at the diagnostic trouble codes. Those codes are available because the check engine light is on. If the fuel pump is not running (momentarily) at key on, that fault alone will prevent the car from starting as there will be no fuel pressure. Pump output and pressure can be directly tested and you can also check for electrical power to the pump. To find out why the engine will not run, the recommended diagnostic is a no start diagnostic. If you request that service, the responding certified mechanic will get this taken care of for you.

ANSWER : Hi there. One of the negative drawbacks to purchasing a retired military or police vehicle is that often the original owners or department will disable many of the electrical system components that power specialty systems (including their emergency lights). This makes it very difficult to pinpoint electrical gremlins like you are describing without being onsite to complete an electrical problems inspection. You might want to set up an appointment to have one of our mechanics come to your location and help you trace this issue.

ANSWER : If the tail lights are illuminated even after you have used the on-off switch to command them off, that means the switch supplying power is fused shut and/or the circuit is being powered when it is not supposed to be due to a wiring fault. To resolve an issue such as that, the circuit powering the lights has to be traced, starting with the devices that should indeed be "off" if commanded off (such as the light switch, relay, etc.). If the brake lights are not functioning, it is possible the filaments in both bulbs are burned out and that possibility should be ruled out first. If the bulbs are OK, the brake light switch and the rest of the circuit will have to be traced. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an electrical circuit diagnostic and the responding certified mechanic will get this problem resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hi there. This type of electrical glitch can be very difficult to pinpoint or diagnose without a physical inspection. However, in general, the most common causes of this issue is an exposed electrical wire within the ignition system. It is best to have a professional mechanic complete an electrical problems inspection first in order to correctly diagnose and resolve this issue.

ANSWER : Hello. Without knowing exactly what wiring work was performed its nearly impossible to say definitively what the issue is. The brake light circuit and the turn signal circuit have crossed paths somewhere. The wires carrying the power supply from the turn signal switch is connected or touching the brake wires. The hazard light button is essentially an additional power source and switch for the turn signal circuit. With both brake lights blinking, the hazard light circuit may be crosses in as well.

Do you own a voltmeter or a way to measure available voltage? You are going to need to trace the wiring work you performed and find where the connection is jumping circuits. Having an official repair manual or wiring diagram will help a lot. Make sure once your issue is found that the wires are secured properly and protected from the elements and from other circuits.

If you’re unable to solve the issue yourself, have a certified technician, like one from YourMechanic, come to your location to diagnose the issue with your turn signals and help you make the right repair.

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.
