Have you reset the TCCM?

Which worked? The reset or the vacuum lines?

Be prepared for the problem to reoccur if the reset fixed it. The conditions that initiated the lock out may reoccur. Cross your fingers that it was a one time thing.
Exercise the system periodically. Maintain it too.

the reset. What I wonder is I was installing a radio so I detached the 4x4 button panel when I pluged it back in I was testing it that is when it was acting strange so it may have had a little hick up i hope that is all it was
