Hi There, It sounds like you may have a faulty coolant fan relay (https://www.yourmechanic.com/services/cooling-fan-relay-replacement). The coolant fan relay helps to maintain the proper coolant temperature by turning on and off at specific temperature thresholds. When this relay is not working...

Be sure the issue is not old or contaminated gasoline and that there is adequate fuel in the tank. Past three months, gas starts to become suspect. Measure the actual fuel pressure on the fuel rail. If fuel pressure is...

The TCM is in the right rear of engine compartment. The first thing to check after putting in a new good battery and checking the charging system is to see if any fuses are blown for the TCM. The engine...

Hello, thank you for writing in. A vehicle that is suffering from a lack of fuel will show low fuel pressure at the intake. Hook up a gauge in line and crank over the engine. If the cranking fuel pressure...

Hi. Your windshield wipers are supposed to work together as they have a mechanical connection to the wiper motor. If only one of the wiper arms is not moving, then you have a disconnected wiper. Under the front windshield trim...

The crankshaft position sensor is located on the driver side of the engine and in the back by the transmission on the engine. If you need further assistance with your crankshaft position sensor (https://www.yourmechanic.com/services/crankshaft-position-sensor-replacement), then seek out a professional, such...

My first recommendation is to have a certified mechanic verify the symptoms with a thorough transmission inspection (https://www.yourmechanic.com/services/grinding-sound-from-transmission-inspection) that includes a road test. Explain to the technician what you are experiencing so they can look out for these things during...

Hi There, What you are describing sounds like possibly low transmission fluid (https://www.yourmechanic.com/services/transmission-fluid-service) or a bad speed sensor or potentially a faulty transmission control module, which also controls the speed sensors. The transmission control module has various sensors such as...

You replaced the accelerator pedal and the throttle body itself. The throttle position sensor (TPS) is a sensor that is located on the throttle body used to monitor the throttle position of the throttle plate inside the throttle body in...

If the starter motor is turning the engine over rapidly, at sufficient RPM, but the engine does not catch and run, that means that there is an ignition, fuel, air induction, or mechanical fault in the engine that will have...

Hi Chris. Thanks for contacting us today. The crankshaft position sensor is located near the front of your Saturn's motor, near the front crankshaft pulley. It is possible that this is the source of your hard to start issue, however,...

Hi Aaron. Thanks for contacting us today. A vibration like you are describing can be caused by a tire/wheel that is out of balance (which can happen even with new tires), a bent wheel, or if the vibration stops suddenly...

You should try and turn the engine manually on front of crankshaft pulley to see if engine is seized. If engine turns over by hand then problem will most likely be the starter. If you cannot turn motor then it...

You should have the vehicle scanned for codes (https://www.yourmechanic.com/article/what-is-the-on-board-diagnostics-obd-system) to see if you have codes to the camshaft or crankshaft sensors. Either of these may cause the no spark condition. If the fuel pump regulator is bad, then you would...

Typically, when a window comes off its track, it is a good indication that a component within the system has failed. When it comes to your Saturn Ion, it may be a matter of removing the door panel and using...

Drain the coolant a little to lower coolant level below thermostat housing. Remove throttle inlet tube for access to thermostat housing under throttle body. Remove upper hose and heater hoses from housing. Remove housing bolts and replace thermostat. Reinstall components...

Hello. From what you describe it would appear that your transmission may be having some potentially serious issues. If the issues suddenly appeared after difficult shifting and a noise it could be possible that the transmission suffered some sort of...

A lean fuel condition may be caused by a number of things. An intake air leak, a dirty or faulty mass air flow sensor (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement), a faulty fuel injector (https://www.yourmechanic.com/services/fuel-injector-replacement), a faulty oxygen sensor (https://www.yourmechanic.com/services/oxygen-sensor-replacement), a faulty fuel pump (https://www.yourmechanic.com/services/fuel-pump-replacement)...

The cooling system would need to be completely checked out to see if the cooling fan circuit is working correct. If the fans are not coming on it would allow the engine to overheat. The thermostat would cause the engine...

Hi there. It's quite possible that the ignition lock cylinder is damaged. However, it could be an internal issue with the steering column that is causing the steering wheel to lock. I would recommend having a professional mobile mechanic come...
