I just replaced the transmission i my sons 1997 Bonneville SSE.  In the
process we disconected the batter.

We have it running again, but now the vents only blow hot air.  the A/C
compressor never kicks on, the temp never changes.

It all worked fine before we diconnected the battery.  All the wires and
vacum lines are connected.

I did see the temp display on the digital display blinking. Is this a error
code or something?

Thanks,

Lannie
