If you can hear the relay clicking, then you may have an issue with the starter. Starters often become tempermental before they fail altogether, so the trick is to diagnose it while it is in failure. If you can access...

Hi, thanks for writing in. Generally speaking, if a vehicle is taking a long time to get to operating temperature you have a thermostat that is stuck open. You can replace it and it will fix your problem. Also, if...

Hello. Though this can be caused by a transmission failure, most of the time it is either caused by a cracked flywheel or a failing timing chain. I usually try to narrow down the location of the noise as that...

This light will usually come on when one of two things are happening. Either the motor is in fact low on oil or the oil pressure sending unit is not working properly and may be producing a faulty reading. I...

Hello - most likely the neutral safety switch, or its circuit, are malfunctioning. If your dome light also no longer works, there will be a blown fuse that also keeps your neutral safety switch from working. I would recommend having...

This sounds like you may not have any power going to the fuel pump relay. The relay wires should have ground on two wires, power on one wire and switched power on another wire. To activate the fuel pump your...

Sounds like its almost time for a transmission rebuild. An automatic transmission has rubber seals inside similar to o-rings. These seals get hard over time and no longer do their job. Letting the car heat up also heats up the...

This may be a sign of a faulty MAP sensor as the vehicle responds adversely to a load put on the motor (i.e. putting it in gear or engaging the brakes). The Manifold Absolute Pressure (MAP) sensor senses engine load...

The engine should be checked first to make sure it is not running too rich. If not running rich then the exhaust catalyst (catalytic converters) are bad and need to be replaced.

Overheating can damage the engine coolant temperature sensor which is an important sensor at start up because it sends a signal to the PCM to enrich the mixture. Overheating can also damage the cooling system thermostat although a damaged thermostat...

One common cause of such noise is a failed outer CV joint on the CV axle. If you peer behind each front wheel, underneath the vehicle, and use a very bright focused light to shine on the rubber boots that...

Hi there. The issue seems to be a vacuum leak on the engine. Get a stethoscope that is made for automotive vehicles and listen for a hissing noise around the intake gasket or the intake hosing to the throttle valve....

What you are describing may be a result of a faulty speed sensor, potentially low transmission fluid or a even a faulty transmission control solenoid. As your vehicle travels down the road, the computer analyzes data being sent by vehicle...

Your car has a heater control valve to control the flow of coolant through the heater core. It is controlled via engine vacuum so that in the case of a failure, it will default to the heat (open) position. Your...

Hi Cristina. The rear lights are typically powered by an electrical relay, that supplies power to individual lights as input is received from the accessory module. For example, when you turn on the headlights, a signal from the module sends...

It is possible that the parking brake cable has seized, due to rust, at that wheel position. That would be relatively easy to determine based on a visual inspection. If you desire that this problem be diagnosed by a certified...

Your car is equipped with a quite a few different safety features, but in order to stay safe on the road and protect both yourself and your passengers, there are a few safety precautions you’ll need to follow. Here’s what...

Hello, thank you for writing in. It is possible the shifter cable or its related components are damaged. They are typically visible from the bottom of the transmission. It should not be hard to inspect that area if you can...
