Re: Lots of threads but still need help - A/C wire help
Purple wire is the power for the blower motor. Purple is attached to the blower relay. Power is supplied to the relay from the fuse you repaired (black wire from horn relay). Dark blue must be attached to the relay for anything other than high speed speed fan operation. High speed wire is the orange wire from dash control. It also is attached to the relay. And the relay needs a ground.
There will also be a ground wire at the blower, it will go to a chassis ground, if I remember right, somewhere near where the AC harness goes through the firewall.
