Climate head doesnt turn on???

wth climate head wont kick on...what fuse is it? does it even have a fuse? reading the labels im not seeing it

Been doing alot of research on this subject overall. I think Fuse 20 may power the IHKA control module. I noticed Fuse 11 feeds the compressor. Believe Fuse 7 is the other one associated with the a/c. No lights at all?

no lights at all..but if fuse 20 is it, then that explains it. i have the new electric fan hooked up to fuse 20 as a switched circuit. ill check that fuse tomorrow then.

that would make sense, as i never saw my aux fan kick in at all when bleeding the system

lots of ihka related things running off 20. ill check my connections.

figured out it was the harness i bought, required a fuse installed for the external device. i had the fuse in the external wire slot thats why climate didnt work
i switched it, and climate work but fan didnt. added a fuse, both work now. so fuse 20 IS an ihka head fuse for those that may need to know this

Thanks for the follow up. Even though the WDS indicates it is, can't be hands on to confirm. Glad you go it going.

No problem. I switched the adapter to radio fuse and had the precise same issue which told me it was my part. But all ok now and for sure found out about 20.
