The blower motor does not work. I would like a wiring diagram of the system. We have tried everything and need more help.

Hi,

I would be happy to help, but I don't know the model of the vehicle. Limited indicates a package the vehicle came from the factory with. I need to know if it is a Century, a Le Sabre, and so on.

Let me know.

Joe

Hi,

Okay, that helps. If you look below, you will see the wiring schematics. The first four pics are for automatic climate control and the last two are for manual climate control. I'm not sure which you have and didn't want to delay you anymore, so I attached both.

I had to cut each schematic in half to make them readable. That is why there are so many below. However, I did overlap them so you can follow from one to the next.

Let me know if there is anything I can do to help. I'm usually good with electrical issues.

Take care,

Joe
