Hi,
I recently replaced the battery for my 2007 Lexus GS 350 and the AC stopped working. The AC button on the panel says "check air conditioner connection. The Audio button also says Audio off, although the ML is working, but It also doesn't show the channel.
I have searched this forum for similar problems. The problem others have found with similar issues have been the connection on the back of NAV and radio, fuses, etc.
I hav checked the fuses and they seem to be ok. I purchased this car used under a year ago and everything was working fine until battery change.
The only modification previous owner has made is an iSimple to listen and o iPod from the car stereo. I have seen others on this forum having same symptoms when newly installed iSimple. Removing iSimple fixed their problem.
Any insight as the steps I should follow to narrow down and resolve this issue is appreciated.

Had my mechanic remove the iSimple iPod gateway and the issue got resolved They iSimple was connected and everything was working till I replaced the battery. I had also searched this forum and learnt others had same problem when they installed iSimple gateway.
