The window regulator or motor is the most likely cause of the window not going down. If you hear the motor running, but the window does not move, then the regulator is broken. If you do not hear the motor,...

The "apparent" oil pressure switch malfunction is not a cause of the stalling or misfiring. That malfunction with the switch has to be diagnosed and confirmed because sometimes there is nothing wrong with the switch itself but rather there is...

When the on-board diagnostic system picks out specific cylinders for misfires, the ignition and fuel delivery systems must be inspected. A misfire on a single cylinder may involve the spark plug or fuel injector related to that cylinder. In the...

There are a number of things that may cause a rough idle. A rough idle (https://www.yourmechanic.com/services/car-idle-is-rough-inspection) may be caused by things such as low fuel pressure, low voltage to the fuel injectors, dirty fuel injectors, a vacuum leak, a faulty...

You are right on track. You may be dealing with several issues at once. The first thing you should do for this starting issue (https://www.yourmechanic.com/services/car-will-not-turn-over-inspection) is check for proper spark. You need to check with an actual tester, and do...

This may be a faulty starter that is going bad or potentially a failing starter solenoid. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity to the starter. When this fails, it may...

There are a few different possibilities here: The engine lost spark, the issue is with your coil, cam or crank sensors, or the fuel pump stopped working. The vehicle would need a diagnostic check to see if you lost spark...

If the vehicle speed is constant, but the speedometer reading is erratic, there is a fault in the gauge cluster or in the signal from the transmission. If, though, you are referring to erratic engine operation, perhaps just at low...

You most likely have a intake vacuum leak. You should have the computer scanned first to make sure you do not have a TPS problem or other sensor issue. Pinch off the vacuum line to the brake booster to see...

When a car has as many miles as your has, the problems really start to stack up until it seems like everything happens at once. Reading and interpreting the codes can be more subtle than it appears.The guys at the...

Unfortunately, no. The only other cars that will interchange with yours are the following: 2000 Chevy Lumina 3.1, 2000 Pontiac Grand Prix 3.1, and only year 2000 for other Buick Centurys. Other transmissions may look the same and bolt up...

If you are not getting a spark from the wires, then there may be a problem with the ignition system, or engine management system. As both systems are electrical, and sometimes highly elaborate in nature, I would recommend having a...

Hi there. A brake fluid leak can cause some serious problems. If it is leaking and getting the wheel wet, then most of the time the problem is the caliper. It can also be the rubber hose going to the...

The leaking brake fluid may be coming from the rear wheel cylinder leaking fluid. Replacing the rear brake shoes, drums, and both rear wheel brake cylinders with springs and hardware should be done. This is the most common repair needed...

Hi there, thanks for your question. I'd be happy to help. A [misfire can be caused by a variety of things other than bad spark plugs such as bad plug wires, vacuum leak, dirty fuel injectors, a weak fuel pump...

Hi there. This vehicle not starting is an indication that the fuel filter and fuel pump are going bad. Over time, the fuel pump will fail and not put out enough fuel pressure to start the car. I would have...

The lack of heat being generated by your system may indicate a clogged heater core. The [heater core]((https://www.yourmechanic.com/services/heater-is-not-working-inspection) is a small radiator like unit that circulates the hot coolant from the engine through the heater core which then uses this...

If the noise is due to worn brakes alone, the pad material may be completely gone and thus the metal backing plate is grinding against the brake rotor when you apply the brakes. It's possible there is part interference as...

The codes describe the conditions in the circuit. A low sensor voltage code may not mean the sensor is bad, it might mean there is a problem in the wiring harness or in the relay for the sensor heater. I'm...

This is usually caused by air pockets in the system. Purge air from the cooling system and see if this fixes the problem. You may have a slipping serpentine belt and should check it for slipping.
