Hi, I have ran across this many times on this vehicle. The most common cause of this is a bad connection at the wiper motor. There is a common issue with the terminals either coming loose or melting causing a...

Check the voltage at the battery terminals for 12 volts at rest. While cranking the voltage shouldn't drop very much, about 10 volts. Jump the vehicle and observe the voltage while it's running. If the voltage isn't above 13.5 volts,...

Hi, thanks for writing in. I would start with checking things such as the O2 sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-oxygen-sensor) and mass airflow sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-mass-airflow-sensor). You should have a check engine light (https://www.yourmechanic.com/article/what-does-the-check-engine-warning-light-mean) on which should have registered some fault codes in the...

Hi. There can by many reasons why the engine is not cranking, the first thing I would check is to make sure that the battery is charged and in good working order. Many times a vehicle will not crank simply...

Hi there. Alert chimes are triggered by sensors located on doors, seat belts and other devices that alert a driver that something is either open or not properly secured. To determine why they are not working correctly, have a mechanic...

Hello, thank you for writing in. Unfortunately, there are a large number of components that can contribute to this issue. The first thing you will want to do, regardless of a check engine light being present or not, is to...

Hi there. Usually the reduced power light is caused by an engine component failure, like the throttle body, TPS or bad O2 sensors. It is very possible that the additional transmission fluid has created a trouble code that might have...

Check all of the battery ground cables to the car on the battery, engine, and chassis. There is a bad ground somewhere that is causing the ECM to not work properly. This would cause the fuel pump to not work...

Hi there. Sounds like the shifter module motor or shifter rail is not working properly. Check the wiring on the shifter module motor on the transfer case and see if the wires are split or damaged. If the wires are...

Hi there. Check the electrical wiring to the transfer case shifter motor and see if there is a voltage present when pushing on the 4WD button. If there is a voltage present, then I recommend replacing the servo motor on...

Your engine is getting coolant into it and producing the white smoke out the tail pipe. The coolant could be getting into the motor from the intake, head gaskets, or head crack. The system would need to be checked to...

Hi there. Check the battery cables and make sure that they are tight and clean. Check the cables that attach to the starter and make sure that they are all tight and clean. The starter remote wire could have an...

Hello. We will be happy to assist you. There are are a few things that I recommend a technician inspect. Fuel should have been inside the filter once you removed it. A test must be done to see if the...

One of the blinking indicators, or the malfunction(s) that it represents, would have to be traced and resolved before it could be determined if they all have a common cause. The clicking noise is actually more likely to be from...

Hi there. The P0708 trouble code (https://www.yourmechanic.com/article/p0708-obd-ii-trouble-code-transmission-range-sensor-circuit-high-input-by-andrew-quinn) means that the Engine Control Module (ECM) has detected a malfunction with the transmission range sensor. A mechanic would begin the diagnosis of the P0708 trouble code by finding the manufacturer’s suggested procedure...

Hi there. Understanding what causes the transmission hot idle warning light is critical to diagnosing your problem. The Transmission Hot – Idle Engine message can be displayed when the transmission fluid is too hot, which prevents the transmission from cooling...

If the coolant level was low due to a leak, such leaks can be found during a leak diagnostic with simple pressure testing. If the cooling system doesn't maintain pressure, and no external leak is visible, coolant could be leaking...

Hi there. Check the gas cap seal and see if there is a crack on it or if there is a distortion on the seal. If there is, I recommend replacing the gas cap. The gas cap seal is designed...

Hi Chuck. That really depends on your tools, equipment and experience. Some professional mechanics with engine lifts and air tools can remove the accessories, motor and transmission mounts in less than two hours. The best advice I can offer is...

Hello, thank you for writing in. The reduced power light will either trigger when there is malfunction with the vehicle and it is trying to protect itself, or when the engine actually suffers a loss in power and is struggling...
