The term "short circuit" is probably the most overused term in technology, but I think it might apply in your case. It sounds like there is some connection or device that is shorting you battery and charging system to ground...

Your vehicle does not rely on a single ignition wire at start up. When you turn the ignition key, many different circuits are actuated, even within just the ignition system (not to mention the fuel system), corresponding to different vehicle...

The electronic control unit (ECU) used in today’s cars and trucks is used to control the engine and other components’ functions. An ECU is a computer with internal pre-programmed and programmable computer chips that is not much different from a...

Vehicle electronics are very sensitive to voltage fluctuation. Crossing battery terminals/jumper cables can do a lot of harm when mistakes like this are made. Your symptoms sound like a shorted PCM (Power Control Module). Since you can't get the vehicle...

If this is the factory light on the dash that says "theft" and is blinking fast, then your theft system is activated. You may need to try another key first after locking all of the doors and waiting a half...

Intermittent issues such as these can be difficult at times. Mechanics can not generally test the components for failure unless the part is actively failing. There are a few common problems that could cause this type of issue. The ignition...

Chime noises, or any alarms for that matter, that just occur out of nowhere represent electrical faults that would have to be traced during an electrical components diagnostic (https://www.yourmechanic.com/services/electrical-components-are-not-working-inspection). The only "connection" between the chime going off when the accelerator...

The BCM or body control module controls all of these items and there is a technical bulletin to get the BCM reprogramed. The reprogram should fix the issue for you. The dealer will have to do the reprogram for you....

Describing the symptoms is very important when your car is not running like it normally does. Only you know what the car usually acts like. If the vehicle is: not starting, blowing fuses, having battery trouble, showing flickering lights, etc.,...

This sounds as though you are having multiple problems that would need to be addressed. The broken latch may be the cause of the dead battery, but not the Check Engine Light illumination, or the radio not working; the radio...

I would agree. The ignition switch (https://www.yourmechanic.com/article/how-to-install-an-ignition-switch-by-robert-tomashek) is sounding like the main suspect on your Suburban. That's the only thing that could lock your steering and then cause instrument cluster to not turn on. If you want to have this...

There are many reasons why your car may not start. Some common causes include a dead battery (https://www.yourmechanic.com/services/battery-replacement), faulty starter (https://www.yourmechanic.com/services/starter-replacement) or starter relay (https://www.yourmechanic.com/services/starter-relay-replacement), fuel pump issues (https://www.yourmechanic.com/services/fuel-pump-replacement), clogged fuel filter (https://www.yourmechanic.com/services/fuel-filter-replacement), and computer or sensor issues depending on...

If the hazard warning lights use the same bulb (filament) as the turn signals, then yes it can't be the bulbs. I would test the turn signal flasher unit. Basically, you want to test for power to the flasher unit...

This vehicle should come equipped with the button to turn off the towing alarm. The owners manual will show where the button is located in picture form. With the alarm staying on, this may indicate a wiring issue or that...

The blower motor only working on high speed is a common symptom of a failing blower motor resistor (https://www.yourmechanic.com/services/cooling-fan-resistor-replacement); but the fact the radio stopped working at the same time is unusual. It's possible that this could still be two...

The solder joints of the microprocessors on S70 instrument clusters are prone to becoming cracked and loose at the circuit board. Sometimes these boards can be repaired by an electronics technician who is familiar with Volvo instrument clusters and has...

Hi! Will be happy to help you. It sounds like there's a short in the system somewhere such as a power wire grounding before it is supposed to. The short has to be in the window switch circuit. I suggest...

It is always an unfortunate experience to have your vehicle stall while you are driving. It is also unfortunate that there can be a great number of reasons as to why your Jeep Grand Cherokee is stalling as well. Without...

Hello. If this occurred right after the vehicle was jumped and after driving the vehicle for a while then the fuses needs to be checked first. This is where I typically start as a battery (https://www.yourmechanic.com/services/battery-replacement) failure or a jump...
