This page is about Chevy repair manuals and why you will most likely be happy with the online version when it comes to GM vehicles.

I will also provide a video at the bottom that shows you what the Chevrolet Tahoe blower motor wiring diagram looks like in the online program.

When it comes to the quality of the auto repair information contained in the all data service manuals it really boils down to what was provided to them. The more information that is received from the manufacturer the more repair diagrams and service bulletins will be contained in the online version of the manual.

Tip of the hat to Chevrolet for providing, from what I can see every drop of information that is contained in their professional dealership chevy repair manuals to the all data information service. Wag of the finger to the foreign car companies that do not supply the best information possible.

This boils down to a raging debate about whether or not car manufacturers should be obligated to supply auto repair information to the public and aftermarket repair shops.
Some automakers are pushing for the right not to make this information available to the public.

If you think about it if this information was withheld then only dealerships would have the necessary information to perform all repairs. The do-it-yourself car mechanic as well as your local repair shop would be left out in the cold.

Chevrolet and the other General Motors products as well as most American car manufacturers believe that you have the right to repair your vehicle. This is why the information that all data provides in its online auto repair manual service is directly tied to the amount of information that is supplied from the car-makers.

Long story short when you subscribe to the all data service not all vehicles are created equally. In fact some vehicles have a lack of quality information.

I have found the best ones to be from Chevrolet, Chrysler and Ford. The Japanese vehicles are well represented like Nissan, Toyota and Honda. I think the worst ones are from German automakers ( My opinion ). Also some Korean made vehicles do not supply as much information as you would find in a Chevy repair manual.

Information from the Chevy repair manuals

Below in the video I do not mention it but the wiring diagram is from the all data online service manual. At the time of this writing their demonstration vehicle is a 1998 Chevrolet Tahoe. This wiring diagram is the same exact one provided in a professional Chevrolet dealership publication.

If you happen to be looking for information on how to repair your blower motor in a GM vehicle this video will probably provide all that you need to get the job done.

If you happen to have a 98 Chevrolet Tahoe then this is your lucky day because the online demo provides fantastic information for the do-it-yourself auto mechanic.

Now I mentioned at the time of this writing because all data does switch up their demonstration vehicle from time to time.

Also note that the blower motor wiring diagram pictured in the video is about the same on many General Motors products from the mid-90s to early 2000. If you are interested in trying out the demo a link is provided below the video.

If you don’t have time now to watch the video or try out the service give this Chevrolet auto repair manual page a . You can also e-mail a link to this page to a friend that may be interested in this topic from the provided button.

Troubleshooting manuals and Two golden rules that mechanics follow. Mark here with some advice on finding and reading repair diagrams.

The first challenge you will face is finding the right diagnostic chart for the vehicle that you’re working on. Once you find the correct procedure or tree chart then you have to read it, analyze it and understand it fully to be successful.

The first step is to sit down and read the diagram until you fully understand how the circuits work. This may take a little while but will pay big dividends during the diagnosis of your specific car problem.

Do not be concerned with how long this first step takes it is not a sign of weakness or lack of intelligence. If you take some time to understand the circuit and the flow of the repair diagram, you will be able to pick out the malfunction, much quicker. Spend some time now and save more time later is how it works out.

Most auto repair manuals are laid out or drawn as a straight line, better known as a ladder repair diagram. Just about every troubleshooting manual uses this standardized approach. This allows you to apply logic and proceed in an organized fashion.

A tip that I have found helpful is to grab a piece of scrap paper and draw the repair diagram by hand. By doing this, it is easier to understand how the circuit operates and flows.

Another advantage of this is that you can make notes on your sketch of the circuit. When you take a pen to paper, it helps your brain rap around the operation of the circuit a lot easier than if you just stare at a picture of the repair diagrams.

Troubleshooting manual rule number two

When you are tracing an electrical circuit using an automotive repair diagram you always want to work from the load back to the battery.

Find the load component first for example light, horn, coil, solenoid or actuator, then find its ground, and then find the battery.

Trying to read a schematic from positive to negative doesn’t work well. Always work from your load back toward the battery. This rule is important because it gives you a correct direction of diagnosis.

When you are studying troubleshooting manuals and repair diagrams, you will note that there is usually only one load component per circuit. This simple fact creates a straightforward diagnosis with better results.

If you are looking at a large repair diagram, and you see more than one load, example starter, light bulb, backup alarm. You will know that each of these items or loads are on separate circuits, and usually run to separate fuses.

In most cases you will find electrical failures isolated to one circuit. If you find yourself jumping around into multiple circuits for diagnosis, it’s time to take a step back and return to rule number one. And go back to study the diagram more thoroughly.

Just like most things in life the more you use a troubleshooting manual, the easier the repair and diagnosis becomes. This is most definitely one case of practice makes perfect.

Studying repair diagrams and learning how to use troubleshooting manuals is an extremely valuable skill. Not just for use in the automotive world, but also construction, equipment repairs, plumbing, and computer system diagnosis all use a standardized ladder repair diagrams.
