GMC Envoy

The check engine light can be reset by disconnecting the battery for a few minutes. If it comes on again you should get the codes read with a OBDII reader. Autozone or another parts supply chain will usually do it for free. The codes are stored on board the PCM and will tell you where your vehicle is having a problem.

If the check engine light ever flashes then it is a do not drive situation.

A good picture for an envoy would depict them in a formal yet approachable setting, perhaps during a diplomatic meeting or a cultural exchange. The backdrop could feature flags or symbols of the countries involved, emphasizing their role as a representative. Additionally, capturing moments of engagement, such as listening attentively or shaking hands, can convey the envoy's commitment to fostering communication and cooperation. Overall, the image should reflect professionalism, diplomacy, and cross-cultural connection.

On the 2003 GMC Envoy, the low-pressure refrigerant recharge port is typically located on the larger diameter aluminum line that runs from the evaporator to the compressor. It is usually found near the front of the engine compartment, often on the driver's side. The port is usually covered by a plastic cap, which is usually marked with an "L" for low pressure. Always ensure the engine is off and the system is properly diagnosed before attempting to recharge.

To remove the cover box to get to the fuel injector on the 2002 Envoy, first remove the intake manifold and the valve cover. You can do this by loosening the four bolts that hold the intake manifold first.Ê

Today is your lucky day, I just changed both of my oxygen sensors on the same year and motor. The first one is located directly on the exhaust manifold in front of radiator as you open your hood on the car look straight down and you will see it. The other sensor is a little more difficult to find by looking straight in the engine. The second sensor is located near the firewall on the exhaust manifold. The only problem is, you have to get underneath the car to remove the sensor. Just follow your converter directly toward the engine intake manifold and you will see it, make sure you have a flashlight, regardless of how much daylight is outside. Once I got under the car a found it, it was easy to come off and replace. Good luck! rljenkins66@aol.com

From what I have been reading, it is a faulty ignition switch. Looks like it has happened to several people too.

It can also be the alternator is defective.

The primary difference is cloth interior vs leather. There are other differences, mostly in options available. SLT will also have things like heated seats and mirrors. The mirrors will have turn signal indicators. They may have self leveling, etc.

you can either purchase a computer programmer ($200-$350+) that will allow you to check and clear codes as well as adjust computer settings for maximum performance or take the vehicle to most auto parts stores that can check the codes for free.

Check with your dealership - there was a recall issued regarding the windshield wipers. They could get water in wiper motor when it rained or when the car was washed and cause the wipers not to function properly. I had an 02 with the same problem. The problem stopped after recall was fixed.

This can be any number of things from bad spark plugs to catalytic converter, crank or cam sensors to map sensor. Have it scanned, find out what code is stored and that will tell you the problem.
