Did you have the rest of the circuit checked before condemning the bcm? It could be but it would be an expensive guess.

I doubt its the bcm I have replaced a ton of bcms but never for inop a/c. Have you tried checking the a/c pressures?Also have seen some a/c compressor clutches fail on those cars.

How to check the for signal from Control Head calling for compressor to turn on? How to check for signal from BCM to ECM. Have ACC control head. How to check if AC pressure switch is not working? I know compressor clutch is fine coz it will engage if I short the ECM AC power control relay to ground.

Where to find an accurate schematic of the Control Head to BCM circuit for the proper connectors? The Saturn HVAC service manual I have gives different wire colors and positions on those connectors than what is under the dash so I am totally confused!

Iam not trying be a jerk just trying to keep these questions when other users search for similar problems with cars they Can easily find possible solutions. Without too much confusion for the moderator answering the questions and the users searching for answers.I have tried answering more then one users questions on the same question. Honestly it just got confusing for everyone including myself. So if you start your own question I will be more then happy to help you. Make sure you list the year model mileage etc for your car. Also as much detail as you can what you have done etc. Iam the Saturn expert on here spent over a decade and half working at saturn dealers. Just start the question off by saying this one is for saturntech9 and the other moderators will leave the question for me. Also list if its auto climate control or a manual one. Thank you in advance for your understanding.
