rear view mirror homelink fuse

cleex024 · 05-22-2013, 08:41 PM

Hey guys anyone know which fuse is the one for the homelink? i just recently got my battery cable recall done and now my homelink doesnt work...the light doesnt even come on when i push any of the buttons.

you guys think it could be a fuse blown out or something worse?

cleex024 · 05-23-2013, 07:57 AM

anyone?

I came across this thread yesterday. Went to hardwire my radar detector and noticed there was no power on the green/white wire for the homelink. Checked fuses and everything is good.

I had my battery recall done around May and noticed yesterday my compass and homelink no longer work. I don't believe I popped fuses, I've done a lot of electrical work before.

Did you find a solution to this problem?

ArtVandelay · 07-06-2013, 04:20 PM

I'm interested too...Anyone?

cleex024 · 07-06-2013, 07:00 PM

oh yeah you have to go into your glove compartment and get into the fuse box...just look at the placement card and find the one that goes to the homelink.

cant remember exactly which one it is but youll figure it out. they just moved the fuse over or something which i dont know why.

jk1112 · 07-06-2013, 09:00 PM

I checked all my fuses and all were good and in the right slots. Are you saying I have to move the fuse over?

yeah but you should check to make sure they didnt move some around...there are empty slots.

Did anyone ever get a response on what it could be for those that had no problem with their fuses? My home link led doesn't light up and my compass doesn't work either.

Anyone ever figure this out? Having the same issue currently.

JayTriggy14 · 06-22-2017, 09:29 PM

I hate to bump an old thread but has anyone figured this out? I recently installed an autodim, homelink, and compass mirror in my 2013 335is. The mirror will not power on and all of the wiring is correct. Please let me know if you can help.

Sorry to bump an old thread again but anyone figure this out? My rear view mirror doesn't dim, compass off, and homelink doesn't work. Ive checked fuses and all fine. Any ideas?

EP11 · 12-15-2017, 12:39 PM

I never was able to figure anything out. However as of recently I began thinking about it again and did some research. I plan on seeing if everything in the coding is "on" such as the compass, etc. I read on the F15 forum that even if its "on" sometimes turning it "off" and back "on" fixes this issue. I'll try it this weekend and see what happens.

mirror get it's power from roof functional center which is integrated in front roof light
roof center in cars without sunroof and after 2007/09 get it's power from F62 F25 F7 fuses
homelink and fla function will not work without ignition enabled

Could you clarify that a little bit? I think I’m not reading your post the way you intended. My car’s production date is 2007/03, any idea where or what fuse it gets it’s power from? Thanks

Checked all these with a multimeter and they're all good. Any more ideas?

Sounds good I'll give it a shot. Thanks for the help!

I replaced my mirror to add High Beam Assist.

The replacement mirror would not light up at first.

I thought there was something wrong with my wiring or the mirror.

Then I read that you had to default code the FSD after changing the VO.

Sure enough after doing this my mirror lit up, the compass came on, etc.

I don't remember if that also affected the Homelink or not, but it definitely affected everything else.

SingleTurbskie · 02-16-2024, 03:09 PM

Mind elaborating what exactly you did. Having issues with my mirror not working at all

opjose · 02-16-2024, 05:47 PM

I default coded the FSD.

If you are not familiar with this I suggest to search for default coding here.
There are several threads that explain the process in detail and the software tools you need to do that.

Default coding which is normally done after a vehicle order change, reverts the module to factory default conditions per the list of hardware the car believes it has in the vehicle order.

In effect the firmware in the module already has the correct programming in place for many different options but does not enable these options until it both reads the available hardware from the vehicle order then is default coded to enable that hardware.

I hope that clarifies it.
