The luminaire used for HID versus non-HID bulbs is different (the photometrics are different). Unless the mechanic replaced the entire enclosure (luminaire) and re-aimed the lamps, the modification you are describing might not pass inspection and may be dangerous if...
OEM manufacturers spend huge sums of money to try to make motor vehicles as quiet as possible, a part purpose of which is to avoid needless hearing damage (a big problem nowadays). Depending on your jurisdiction, there may also be...
Hi TeeJay. Thanks for contacting us today. This is typically a computer software glitch with GM cars. It is also possible that an electrical relay is either damaged, has a loose electrical connection or even an electrical glitch behind the...
A scan tool should be applied to measure the actual engine operating temperature. Gauge and/or temperature sensor/sending unit malfunctions have to be ruled out. if the car is in fact overheating, a plugged radiator, a faulty radiator pressure cap, collapsed...
If by chance the fuel level is really low and you drive up a steep enough hill, the car could stall. There are other causes of intermittent stalling, though, such as intermittent electrical connections on key circuits (fuel, ignition, etc.)....
If there are air leaks in the air induction system (e.g., the snorkel) that allow unmetered air into the intake, that circumstance could cause the two codes, P0171 and P0174. In all case, prior to performing any diagnostic on an...
Test the fuse that you removed to be sure it is intact. If the fuse was pulled while the circuit was powered, that can cause it to open. Once you are sure that the fuse is intact, be sure that...
The algorithm in GM's oil life monitor system does not "know" anything about the quality, type, brand, rating, certifications or viscosity of the oil you are using. Rather the remaining "life" of the oil in your vehicle is inferred based...
The most common causes of overheating include trapped air, low coolant level (including that due to leaks), a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or...
If you are still under a factory warranty then I would recommend letting the dealer diagnose and take apart the cooling system or engine as needed and get a loaner car while the work on it.
Hi Dean. Thanks or contacting us today. Sometimes this type of symptom is caused by a warped brake rotor, while in other instances, an excessive build-up of brake dust or other debris trapped in the caliper can cause this type...
Hi Shelly. Thanks for contacting us today. It really depends on when the clanking noise is occurring that might pinpoint the source. If you hear the noise before shifting into gear, then it's likely that you have a cracked exhaust...
It is possible that this could be a fluke malfunction. It is also possible that there could be an actual issue with the airbag system. I would recommend having your airbag system inspected by a qualified professional to determine the...
Hi there. Thanks for contacting us today. There are a few things that can cause a catalytic converter to wear prematurely. The most common is excessive use of aftermarket fuel additives or using either poor quality or leaded gasoline (racing...
Hi Dustin. Thanks for sending your question to us tonight. The blinker on the dash blinks fast when there is a light bulb on that side is burned out in most cases. This is likely the source of the turn...
As you face the crankshaft pulley, the pressure sensor is installed just slightly ahead of the no 2. fuel injector. It will be just slightly to the right of the center line of the engine as you face the crankshaft...
You would need to check for power to the connector wiring when lights are activated to see if the problem is in light sockets or the body control module and its wiring connection to narrow the problem down. You may...
A common cause of failure to shift is a shift solenoid failure. Other possibilities are faults in the vehicle speed sensor and external controls such as the throttle position sensor. The shift solenoid(s) can be ruled in or out on...
Loss of power on acceleration, as well as rough idle, can be due to plugged fuel injectors, faulty oxygen sensors, fuel pump and/or filter, vacuum leaks including that caused by a faulty EGR system, ignition system malfunctions, bad valve timing...
Be sure you have not activated any interlock (safety switch, often a push button on driver side typically) that will disable individual window activation. A fault such as this is usually due to an electrical failure. If none of the...
