I think I found your reply, my vette has dual climate control, it's a daily driver, 80,000 miles. No hvac codes shown.

Please let me know what else you need to know.

You're going to need these 4 documents to go further. Using the schematic, you should now be able to pinpoint where power is being lost. But you also need to understand how the system works also and that is why I included the other documents.

Don't hijack this guy's thread, keep your issue separate. Post your information in your thread so that the issues don't get intertwined. That only causes confusion. I will address your issue in your thread.

Wait a minute, now I'm confused. This IS your thread. Let me make sure that I'm giving the right poster the right documents.

EDIT: Okay, those documents are for you. I am in 2 different AC threads at the same time and got you mixed up with someone else. Disregard the hijack comment, YOU are the OP and thus, you can't really hijack your own thread.

You sent me 4 documents including a wiring diagram of the ac system, I am ready to continue troubleshooting my problem, waiting for instructions and guidance. Any advice you can give me is greatly appreciated.

I sent you 4 documents, three of which explain EXACTLY how your AC system works. You also have the wiring diagram to how everything is connected. The first step to trouble-shooting electronics is to understand how the device works. The second thing you need are the schematics that show how everything is connected and how each circuit of the device received power. At that point, you get out your multimeter and test light and start walking through the circuit, armed with the knowledge of how it works and knowing how it is connected. That's the way any mechanic that you take your car to is going to solve your issue if they are worth anything.

Now it sounds like you don't understand what I've sent you or you would have dived into this thing already, especially since you now have the schematics. Now if you don't know how to read automotive schematics, your next step would be to take your car to an AC mechanic. The only way I can help at this point is to come over and trouble-shoot it myself because what I sent you is exactly what I would use to figure out the issue. That's why I sent you those documents.

I may have to read an automotive document like these 20 times, line by line before the light bulb comes on and tells me what to do. But that's how I learned to work on this car and for the most part, it is the only car I work on. If you are going to be turning screws on your wheels, you have got to understand how it works. You have to start somewhere and this appears to be where you start. At this point, the only thing I can do is help you understand what you are reading but the engineers who wrote the service manual did a real good job of explaining how this car works. You have their words in your hands.

OK, Junkman, thanks for your reply.

I am really good at mechanical stuff, electronics leave me scratching my head. I guess I was expecting a response that would give me a place to go and a part to remove.

I can tell you that after reading a thread somewhere a week or so ago, I learned you can get the blower motor to run by running a wire from the motor casing to ground, and control it by putting a switch between them.

I did that, and I now know that my blower motor works, running on the highest speed, and all the controls in the AC system work, except for the fan speed switch. If I switch from fresh air to recycled air, the motor goes to the higher speed. I can control output to defrost, footwell and dash outlets. I can control output temp from high to low by degrees. Air temp will rise or fall as I change the temp knob.

So I hope that explains to you what my system is doing, and not doing. If you can now tell me where to go and what to remove and replace, I will be eternally gratefull. Otherwise, I guess I'll be spending the big bucks to have the AC mechanic do the repair.

Thanks again for any advice.

I still can't tell you what to replace without putting hands on it myself. However, what I can tell you is what NOT to replace. Obviously the blower motor works, which was what you were thinking about replacing. That would have been a major waste of money because you can't return electrical parts once the package has been opened. I can also tell you where you need to be looking and that would be the schematic that I sent you. Knowing what you know now, why haven't you used that schematic to verify that you have a solid connection from your blower motor to ground? Your issue is on that schematic. All you have to do is READ it and use it.
