HVAC Vacuum Leak?
I removed the PCM from my '99 vert to send to the Vette Doctor only to find 2 corroded & broken vacuum lines running from the vacuum tank and check valve behind the PCM. Any idea where these vacuum lines go to and how to access where they go to? Any help would be appreciated.
Thanks,
Mike

imho;
1 line goes to the back of the manifold and the other line goes to the inside ac controls with the center of the check going to the vacuum tank, i replaced my broken check and broken hoses with a plastic t and rubber hoses from napa for about $7. works great!

Thanks for your reply. Does the line from the vacuum tank check valve go to the manifold and the other one from the tank go to the inside a/c controls? Is there a diagram in the 3 book Corvette Service Manuals? How do I access the a/c controls?
Sorry for all the questions!
Thanks again,
Mike
