Hi Adele. Thanks for contacting us today. There are several possible reasons why your warning lights are illuminated, and likely are the source of the noises you're hearing as well. Some of the possible sources include worn tie rod ends,...
Hello. Fluid pressure is used inside the automatic transmission to convert the engines rotation into working torque. Any major leak inhibits operations, fluid pressure cannot build properly, and the transmission starts to slip as it cannot transfer the power. There...
There is a TECHNICAL SERVICE BULLETIN for the problem and need to reprogram the PCM to a new level. The code is for a cam sensor signal being misread by computer and this TSB needs to be done before replacing...
For the sake of clarity, it is important to distinguish when the car is overheating. If it is overheating when the car is moving, then the fan clutch isn't your only problem. If the car only overheats at a stop,...
It sounds like you have a wheel bearing (https://www.yourmechanic.com/services/wheel-bearings-replacement) going bad. Noisy wheel bearings will only make noise when the car is in motion. They will get louder the faster you go. They also change pitch, or get louder or...
Hi there. There is a possibility that your alternator or charging system may have experienced a failure. In the case of a charging system failure, the battery's charge cannot be kept and the battery drains during vehicle operation. Once the...
Hi, Since you have already been working on the problem you would have to have a certified technician come and diagnose the problem you are having (https://www.yourmechanic.com/services/car-does-not-shift-from-park-to-drive-inspection). The gauges jumping around either is a low battery or you have a...
This is a very common problem for your type of vehicle. Most likely what has happened is that the blower motor is going bad. As a result of that, it is drawing too much current. What is likely to be...
This issue is very common and is typically related to a worn out ABS Speed Sensor (https://www.yourmechanic.com/article/how-long-does-an-abs-speed-sensor-last). The function of the speed sensor is to monitor the way the tires rotate, and make sure that the ABS system is triggered...
Hello, thank you for writing in. The vehicle may be having a catalytic converter issue. When the catalyst inside of the unit fails, it can chip off into chunks and rattle around in the case. The sound amplifies when the...
Hi there, thanks for writing to YourMechanic. It can be difficult to drive a vehicle with it stuck in reverse. The problem seems to be a plastic grommet that connects the gear shift assembly to the transmission. It sounds like...
Hi. Other owners have reported similar symptoms with their trailblazers. The first and easiest thing to check would be the 125A mega fuse under the hood. This is located right outside the under hood fuse box and has two big...
Your oil pressure gauge works by using a sending unit that is mounted down on the engine block that reads the oil pressure inside the motor when the engine is running. As the engine RPM's go up, more crankcase pressure...
I would suggest checking the timing and checking for vacuum leaks. Misfiring is typical when the timing is not accurate as it relays inaccurate orders to your car's ignition system. Vacuum leaks can also cause this as they can create...
Hello. I usually start by checking the battery (https://www.yourmechanic.com/services/battery-is-dead-inspection). If it is low enough these other systems will work but there will not be enough power to engage the starter. If the battery is fine then most of the time...
Check the turn signal switch and see if its sticking in place. A bad turn-signal switch may interrupt the brake light circuit and cause the brake lights to not function. Also a broken wire to or from the brake light...
Hello: Most acceleration issues that are accompanied by a sound are typically an indicator that a vacuum leak exists or that an exhaust leak exists. To know for certain, you'll need to have a professional mechanic complete an engine is...
You should have the computer scanned for additional codes and also check the fuel pressures to see if the no start is a computer sensor issue like crankshaft sensor or the fuel pump is not giving pressure.
Replacing parts until the car is fixed can be a very expensive way to do a repair. A thorough diagnosis can save you time and money. But if you have misfire codes, the last digit of the code should indicate...
