Was installing a Eonon stereo, everything worked fine, then i realized the climate control doesnt work. Everything was plugged in but still didn't work. Climate control has no power what so ever, it wont light up at all. Plugged in the factory stereo still didnt resolve the issue, replaced every fuse i could think of.

Has anyone encountered this issue before, or may know what the source of the problem is.

Thanks

Add Build Month/Year to that.

It's hard to "clean-up" after "One's self" (Due to "Denial" ;-). Rules of Diagnosis:
1) If it worked before "SOMEONE" (including THOU) took things apart to work on something else (like dismantling Dash/Console?), then most likely cause of new issue is that SOMETHING(s) were NOT properly reassembled/ RE-Connected.
2) If you had INPA/ISTA, or something that can quickly read faults in ALL Modules, or determine that the IHKA Module is NOT communicating/ responding to Software/Scan Tool Query, that would strongly suggest an open circuit in power supply to the IHKA Module, or Blown Fuse.
3) TIS has Online circuits with which someone familiar with their use can quickly find the power supply fuse, wiring, and intervening connectors, with "Installation Location" of each connector or component.

"Tunafish" is more than "familiar".

So supply requested info, or DIY by going to newTIS.info site:

By everything working fine, means everything thing was OEM. This is the 1st aftermarket stereo in the car. Before i installed it climate control was working fine, nothing was tampered with before the install.
