I replaced my battery and now my A/C and Heater console doesn't work.

You may want to check for fuses in the battery junction box. I don't have the exact one listed in front of me, but I would guess there is a fuse for the EATC unit.
All of the fuses are good. The display just shows blinking numbers and won't cut on at all. Thanks for your response also.
In that case, it needs a replacement control head. There's nothing really else to do with it. Sorry for the news.
Thx I figured it out and everything is working now. The battery terminals weren't tight enough so I removed the plastic piece on the positive part. Thx again.
