Older systems use a movable vane in the intake stream called a Vane Air Flow (VAF) sensor. The VAF sensor used in Bosch L-Jetronic, Ford, and most Japanese electronic port fuel-injection systems is a movable vane connected to a laser-calibrated...
Hi there. The turn signals could be not working for an electrical issue in the circuitry from the switch to the system. Check to see if the hazards work on the vehicle. Even though the hazard switch is in a...
Hello and thanks for writing in. Depending on what the vehicle does when trying to start it may help to narrow this down. If it produces a click sound, this may be related to a faulty starter solenoid. If it...
Check the wiring harness from the gauge cluster to the speedometer and see if the gauge is working. If the gauge is not working, then the gauge cluster would need replaced. If the gauge is working, then there could be...
The blower motor only working on high speed is a common symptom of a failing blower motor resistor; but the fact the radio stopped working at the same time is unusual. It's possible that this could still be two separate...
Check to see if you are getting power to the white wire to the driver's window switch when the key is on. If not, then check and replace the ignition relay 2 in the engine fuse box. The main circuit...
Hi there. Check the wiring from the starter to the ignition switch. There is a loose wire or a break in the wiring that connects the starter solenoid to the starter relay. Make sure that all of the wires on...
Hello. I would recommend first disconnecting and cleaning the battery clamps and battery with baking soda and water. Once the terminals are clean then see if it will crank over. You may need to jump start the battery if it...
A few different things have the potential to cause the transmission faults you have described. The most common would be a transmission position sensor/range switch, neutral safety switch, shift solenoid, low fluid level, or the transmission itself. I'd recommend getting...
Hello. It sounds like you may have a short in your electrical system somewhere. I would recommend having your electrical system inspected by a qualified professional in order to determine where the short is located. This will include loading up...
Hi there. Check the fuse to the turn signals and see if its blown. If the fuse is not burned, then check the wiring from the switch to the turn signal lights. Use a digital ohm meter and see what...
You would need to check the temperature sender unit to see if it got coolant in the connector or wire got shorted somehow. Disconnect the sensor and see if the gauge acts differently. If it does then replace the sensor...
Intermittent issues such as these can be difficult at times. Mechanics can not generally test the components for failure unless the part is actively failing. There are a few common problems that could cause this type of issue. The ignition...
Check the wiring to the throttle pedal position sensor on the gas pedal and see if there is a loose or broken wire in the pig tail. Fix any wires that are coming apart and wrap up the wiring with...
Hi! Will be happy to help you. It sounds like there's a short in the system somewhere such as a power wire grounding before it is supposed to. The short has to be in the window switch circuit. I suggest...
This sounds as though you are having multiple problems that would need to be addressed. The broken latch may be the cause of the dead battery, but not the Check Engine Light illumination, or the radio not working; the radio...
Hi there. If the wires connected to the mass air flow sensor (MAF) was broken and all of the wires were touching each other, then the wires would have shorted out the MAF sensor. I recommend repairing the wires and...
Hi there. If the headlights are burning out a few days after replacing them, there could be an electrical short in the wiring for the lights causing them to overheat or the ballast resistor is not working causing the headlights...
When reversing the jumper cables is the same as reversing the battery cables. It burns up the fuses, relays, electronic circuits and possibly the computer. If the fuses were replaced and everything in the car is working, then either the...
You had a good start by tracing the wires and making sure they were clean, dry, and not damaged. To make sure you covered the entire circuit, I recommend you use an official wiring diagram to check this. It is...
