digital dash and a/c doesn't work right afternew battery installation

by Joel Cox
(Waco,TX)

Intalled new car battery and dash has worked properly once since then. at that time the a/c also worked, but after restarting again everything is whacked out again. Sometimes half the dash lights up, other times it's totally dark. Then sometimes Every value lights up as though you had just turned the key to the on position, prior to cranking. Dash obviously has power to it. But, I'm losing AC clutch trigger. Then blower works on all speeds, as does the digital thermostat and outside temp reading. All that was done was a battery r and r. Any ideas? All fuses check good as do fuse links around battery.
