Default HVAC code
On my 03 Coupe it is showing code B0333 which is the outside air temp sensor open. What part do I need to fix this and where is it located? Please be specific.

The sensor is under the front passenger side facia. Just unplug the connector and clean it. They tend to pick up a lot of crud and corrosion down there.

Apparently, my air temp sensor is missing. There are two electrical wires with connectors hanging loose. One is for the horn (currently disconnected) and the other is for the air temp sensor (which is missing).
How do I identify which set of wires goes to the horn and to the air temp sensor?

Is there any system you don't have a schematic for?

every plug is different. It only plugs into the correct mate.
