The electrical system that is on a car plays a large role in ensuring that everything is running efficiently. There are a number of different things in a car that will require a...
The job of the electronic spark control is to control the engine timing. This part can also be called the "knock sensor", as it monitors any unusual knocking, or vibration that...
Your vehicle depends on electricity in order to run, and this electricity can be traced back to the spark plugs which create a spark to ignite the fuel. It’s a whole...
So much of your vehicle relies on electronic components nowadays. They all work in conjunction with one another, so that means when one fails a domino effect takes place, and they...
With all of the danger on the roadways, finding a way to keep yourself and your car safe should be a concern. A car has a variety of different mechanisms that are...
You probably have a dead battery. The computer systems on your car will be prone to odd behaviors when the battery voltage gets low, so you may see lots of things that don't make sense. The battery could be dead...
These all sound like separate issues. They probably presented one at a time. If you hear a sound in the door when you push the button for the window, that would indicate a mechanical malfunction in the window mechanism. Electric...
I would recommend you do a careful check of all the lights on the car to be sure that these aren't the only ones that are out. It's possible that these things are all on a single circuit and you...
You could be right about a fuse, or it could go deeper. There are two circuits for the console lights, one makes them go dimmer when you turn on the headlights. That's why things change when the headlights are on....
If you are very lucky, you may just need a battery. When you cross the jumper cables, you can do a lot of damage in the blink of an eye. If it just trashes the alternator and the battery, you...
Hello, thank you for writing in. The charging system is rather simple including the alternator, battery, and the cables. If you have tested the alternator off of the vehicle, there may be another component in the system that is causing...
The electrical element in your ignition switch is probably failing. In many cases, that part of the switch can be replaced without replacing the lock, so you don't have to mess with new keys. If you continue to hear grinding...
Hello, thank you for writing in. The short with the battery may have damaged fuses in the main fuse box. To check this, you will want to either visually inspect all of the fuses, or use a multimeter to electronically...
Hello, thank you for writing in. Great job on the electrical testing thus far! A wiring diagram for the vehicle will work wonders for you if you can obtain one. If you are referring to the ignition switch fuse, then...
Be sure the bulb filament is intact, although if the turn signal works, as you say, when the headlights or parking lights are off, the filament is probably OK. For some reason, the turn signal circuit is being interrupted by...
Hello, thank you for writing in. The vehicle may be having a programming issue. The security system may be locking you out as a result. You need a high-tech scan tool to properly pull enough information from the vehicle to...
Hello, thank you for writing in. The wiper's motor circuit may have a short somewhere that is blowing the fuse. Weather can not only cause corrosion but can stress out the wiper motors and cause them damage as well. Both...
There is a good chance that these are all on the same circuit and you have a blown fuse. Check your car's owner's manual for the fuse panel location and you can check. Most fuse panels have a description of...
Hi there. If there is a fuse that is blowing then that means that you have a short circuit. That can be anyplace in the electrical system which also includes the fuse box. I would need to know which fuse...
That's a curious mess of problems. I would first suspect a problem in the ignition switch itself. The switch has several separate circuits and one of them may be dropping out causing the seeming random failures. Since your transmission is...
Hello, thank you for writing in. The passenger (right) side of the vehicle (on yours and a lot of other vehicles) holds a computer system behind the fender (just under the floorboard). This is the box that controls the power...
Hello, thank you for writing in. There are several reasons why the hazards might turn on when you open the door. Typically when you open the door the jamb switch which controls the connection to your radio and interior lights...
You probably have the wrong bulbs in the sockets. Your car likely uses an 1157 bulb, a bulb that has been in use since the '60's, but bulbs have been changed and part numbers superceded over the decades so it's...
Hello, thank you for writing in. Electrical issues with the anti-theft system can mess with the functionality of the vehicle. This does not mean that this is the cause of your problems, but is worth inspecting further. If it feels...
Hello, thank you for writing in. The first thing to check is the installation. Make sure the power supply was hooked up correctly, as LEDs are polarized and must be wired perfectly. Secondly, you want to make sure the wires...
