I have a 2003 Mazda 3 with a strange issue. The AC wasn't working, and I found that the relay wasn't closing when the button in the cabin was pressed. The actual relay is fine. I opened up the relay and was able to manually close it to engage the AC, which worked fine.
I'm having trouble finding the right service manual or schematic to figure out how to fix this. Does anyone have any ideas about where I could look next to fix this?
