The dreaded C.E.L.
Few things are more ambiguous and more annoying than the check engine light. What does that even mean? The short answer is, it can mean many things.
Different manufacturers have different parameters for what will trigger a check engine light. Often it’s something relatively minor, like a momentary error code or a sensor has failed.
Generally speaking, if you see a check engine light and the car is still operating normally, isn’t overheating, isn’t shifting funny or acting strangely, it’s not an emergency. In such a case, you should make an appointment and get into see us within a day or two.
If your vehicle throws a C.E.L. and it IS acting funny, you need to get it to our shop immediately. If you don’t, there’s a very good chance the vehicle will stop running altogether very shortly. There’s also a chance that you could do some serious damage to your engine if you keep driving or in some cases, it can be a fire hazard.
Once you get the vehicle to us, we can run a diagnostic scan in an hour or less to help determine the problem.
We all the feeling – the A/C stops blowing cold. Maybe it’s kind of cool, but not really cold. That can only mean one thing: there’s a problem. Bring your vehicle to us if your A/C stops blowing cold if you smell something funny from the vents. The sooner you get it fixed, the more money you’ll save.
A pressure test of the A/C system is among our first course of action. From there, we can isolate the problem and develop a plan of action to remedy the situation.
Sometimes it’s just a leak in the system, other times it’s an electronic module or component that’s gone bad. Whatever the issue, A/C repairs are no problem for us because we have the equipment to fully diagnose and resolve the problem quickly.
The best course of action is to have your A/C system inspected annually. We offer this service to our clients, but suggest that you book in the Spring to prevent the Summer rush…and the Summer misery.

Check engine light – What does it mean?
If the check engine light illuminates, it will either blink or remain constant, depending on the problem. Either way, you should have the vehicle checked by a Qualified Service Technician as soon as possible.
If the light is steady, the problem is not an emergency, but you should schedule an appointment as soon as possible.
A blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system. There it can quickly raise the temperature of the catalytic converter to a point where damage is likely, requiring an expensive repair. If this occurs, you should reduce power and have the vehicle checked as soon as possible.
Today’s automotive computers often try to compensate when there’s a problem: so you may not notice deterioration in performance, even though your fuel mileage is suffering and your vehicle may be emitting unacceptable levels of hydrocarbons and/or other pollutants.
If the check engine light comes on:
Look for a serious problem that requires immediate attention.
Check your dashboard gauges and lights for indications of low oil pressure or overheating. These conditions mean you should pull over and shut off the engine as soon as you can find a safe place to do so.
Try tightening your gas cap.
This often solves the problem. Keep in mind that it may take several trips before the light resets. Some vehicles have a separate indicator that warns of a loose gas cap before the condition sets off the check engine light.
Reduce speed and load.
If the check engine light is blinking or you notice any serious performance problems, such as a loss of power, reduce your speed and try to reduce the load on the engine. For example, it would be a good idea to stop towing a trailer. Have the car checked as soon as possible to prevent expensive damage.
Have the code read and the problem fixed.
Take the vehicle to a professional. Some automotive parts stores will read and interpret the code for you. However, unless there is an easy solution to the problem, you should have the vehicle diagnosed by a qualified service technician directly to identify what’s wrong. This is where the real meaning of codes comes into play. The only thing a code really indicates is which system or circuit to test in order to isolate the actual problem.
Each numerical code has a matching-numbered test procedure. Following that test will direct you to the problem. Each step of each test must be performed in absolute sequence. skipping steps or performing steps out of sequence could make the entire test worthless. Tests may also give you voltage, resistance, temperature, or time specifications, which are exact values. Close doesn’t count.
Don’t confuse the Check Engine light with the maintenance reminder or service interval light. These lights illuminate when a routine service is due. They are usually triggered by mileage, amount of fuel consumed, or some other type of vehicle-use measurement.
