Check Engine Light is on (Inspection)
The check engine light comes on when the engine management system has detected faults in the engine or transmission. The problem can be as simple as a loose gas cap or as complex as internal engine damage.

Are you able to turn the ignition key?

When you turn the key, do you hear the engine trying to start ( do you hear the engine cranking?)

Explanation
In our experience, it is unlikely that the battery is dead. Your car may have a problem with the fuel or ignition system, or there is a mechanical damage (e.g. broken timing belt).
We Recommend
Car is not starting (Inspection)

Do you see any indicator lights in your dashboard?

Explanation
In our experience, this could be an issue with the starter motor or any of the other components in the starting system circuit.
Please Note:
If you see a flashing key sign on your instrument cluster or dashboard after the ignition is turned on, then you have an issue with the anti-theft or immobilizer system in your vehicle.

Explanation
In our experience, it is an indicator that the battery is discharged. It is also possible you have a defective battery or component in the charging system. This problem could also indicate a deeper electrical problem which would require diagnosis.

  • Fuse is bad
  • Master switch pack is bad
  • There is a wiring issue

When you try to close or open the window, do you hear a whining noise (noise coming from a motor inside the door panel) as if the motor was trying to move the window?

Explanation
In our experience, most of the time this problem happens because:
Window regulator is broken
It is also possible that:
  • Window track is broken
  • Some hardware is loose inside the door

Explanation
If you turn on the heat, and you don't get any hot air coming out from the vents, the common reasons for that are:
  • Thermostat malfunction
  • Heater core is clogged
  • Heater control valve is malfunctioning
  • Blend motor is not working properly
There are few things you can check. If the temperature gauge is not moving up to the proper operating temperature when you start the car, more than likely the thermostat is stuck open (you need a new thermostat). When you turn the fan on high speed, if you don't get a proper amount of air coming out, then the problem could be with the blower fan or resistor or even clogged cabin air filter. Our recommendation is to have a mechanic diagnose the problem.

What is the problem with your heating and AC system?

Explanation
If you turn on the heat, and you don't get any hot air coming out from the vents, the common reasons for that are:

  • Thermostat malfunction
  • Heater core is clogged
  • Heater control valve is malfunctioning
  • Blend motor is not working properly
