My climate control module does nothing, no lights for AC, Rear Defrost, Aux AC or recirc (backlights work with headlights though), no fans nothing. Have done the following:

Checked the voltage at the red wire into the back of one of the connectors to the climate control module and had +12v. Replaced the front blower and blower resistor module. Checked and double checked all fuses. Swapped the Run/Crank relay with a identical one. Replaced the climate control module with one from amazon and it does the same thing as well.

It just stopped working out of no where last week. The rear AC controls do nothing either. I bought a haynes manual but the wiring diagram is a joke. It does not have connector diagrams or pin numbers to ring out.

Any ideas?

Thank you!
