Pull the left panel off the center console. You'll see the diverter flap vacuum pod. The evaporator temp sensor is just below it.

Before you do that, though, check that:

- the low refregerant switch on the dryer isn't open

- fuse 11 has +12V at both ends with the key in run position

- the AC relay pin 3 has +12V with the key in run position

- the AC relay pin 4 has +12V when the ACC is on defrost (engine running)
