Does anyone have a schematic or detailed info on this box including removal or other problems associated? I have a horn problem as well as both inside 12volt outlets (cigarett lighter type) are dead. The fuse was blown on the horn but a new fuse didn't help. The horn relay is NOT getting energized. any help appreciated.

 

If you need the schematic for identifying each fuse, it will be in your Owner's Manual OR on the lid of each fuse box cover.

If you do not have a manual, there is a "Sticky" in the General tab of this forum, that will allow you to electronically look up or down load a Owner's Manual for eash year.

EDIT>>>> You didn't mention what year HHR you are speaking of. But the 2006 (which I have, but haven't had the problems many are concerned about) has been notorius for electrical problems.

 

go to this thread https://www.chevyhhr.net/forums/deleted-threads-41/my-hhr-links-r-here-hhr-tech-manual-24774/ which is in the STICKY section of the General HHR section. Bser2000 has all the wiring and info which you can download and save in your documents on your pc. It can take awhile to download but it worth it. It is all for the 06 HHR but I'm sure most is good for all or close, for a few yrs.
