I have had a new 'brain' put in the car. I was told I needed a new module? But what kind? The ac won't even come on. Speedometer works, so does radio. Please help!

Do you
have the same problem?

We need pressure numbers as it will depend on starting up the system with the correct pressure

The problem here is 1 off the panels is bad. Use a t15 to remove the wood grain. Then u remove the fuel center and a/c panel. Start by disconnecting the fuel panel connector. Does the a/c panel light up?If no plug the fuel center back in and unplug the a/c panel. Does the fuel center lite up?If nethier panel lites u will need to replace the bcm.
