A/C has stopped working. The blower is not working. I hooked it up direct to the battery and it seems to work fine. Compressor is engaging you can feel it cold, but it is not moving the air around.

This could be a couple things causing the blower to not come on. The easiest way to find this is to start at the blower motor and check for power. Then go backwards in the system until you find where the power is. That will tell us what the issue is.

Here is a guide on this issue:

Also, here is a guide that will help with this testing:

Lastly, I attached below the wiring diagrams so that we can work through this. Let us know what questions you have. Thanks
