Auto folding mirror mod - Anyone?

[MDC9966]

2007 Suburban LTZ, does anyone know of a module or hack that will auto fold the mirrors when the SUV is turned off at the key, or by the remote?

Seems like I'm always stuck parking in a tight space with the Sub and usually remember to fold the mirrors in at the switch. But thought if there was a module or mod or hack of some kind to relay a signal to that switch to fold them in when the vehicle is turned off, that would be helpful.

It sounds simple but maybe not. I wouldn't want to get into the command center, just a relay of some kind triggered by the vehicle going into park or shutting the engine off that signals the switch to fold them in.

Anyone seen this, know of mod?

Anything is helpful, I"ve searched the forum and google with no luck, maybe I'm not looking in the right place.

I haven't seen it done... but I doubt it could be that difficult.

I would think perhaps a DEI 611T would be able to get the job done.

If I were going to do it I would probably wire it to fold the mirrors in when the doors were locked VS ignition off... but either should work.

It's an option in my DIC on my 2012 denali

Not on my 2008... I just checked... lol

I did find this which shows how to wire them if you don't have power fold from the factory.

Seems like a DEI 611T in place of that rocker switch would probably do it.

Or perhaps..

Now substitute a DEI 528t combined relay/timer for the above relays to give you a timed pulse (about 3 seconds each way).

Since it was a factory option on the newer trucks, it can probably be programmed into the BCM...

They can program all kinds of cool features.

wams does alot of cool stuff with ecm and bcm programming even adding features that never existed. however adding a simple relay set in to trigger when they lose power isnt too hard. if you dont feel comfortable doing it yourself a local custom shop (audio or full custom) could handle it with probably a fairly reasonable price.

 

[MDC9966]

That's a good idea, I'll ask. If anyone on here as already done it though, chime in with the parts. I'll be glad to document it and post for the next person.

Quick question, if i run a jump wired from the lock side of my power door locks to the fold in side of the mirrors, would that work?

 

[Doubeleive]

don't think so the nnbs are almost full serial bus commanded, the power fold is controlled by serial command from the bcm, it's going to take a bit of work, going to be much easier to just have it programmed

If you connected a jumper between the wire that sends power to the actuator and the "fold in" wire on the mirror it would start to fold in but would loose power since the actuator doesn't need power for an extended period of time as it is just a quick pulse.

But as @Doubeleive said... everything is controlled by the BCM and it could potentially cause issues.

You still need a time/delay relay to apply power to the mirrors long enough to complete the folding process.

So if I used a relay and jumped the wire it might work?

 

[kbuskill]

If you used a timed latch relay then it should.
You would need the relay to stay latched for 3-4 seconds after it received the signal from the door locks.

You would also need a 12v+ and ground source.

But keep in mind that everytime your doors lock the mirrors would fold... so if you have it set up to lock the doors everytime the truck is placed in gear or at a certain speed then your mirrors would fold in.

Also you would have to hit the button to fold them out everytime as they wouldn't auto fold out just because the doors unlock.

Something like this would probably work...

that's a good point, I thought about that and since the parking lights flash when I hit my remote to lock and when I do it to unlock. I thought about doing what you recommend, but jumping it from the parking lot flash?

 

[Doubeleive]

The time and labor involved and parts far outweighs simply having the option programmed, on my 2012 Denali it is already a option in the DIC so I would think it can be programmed in.

6 of 1 and a half dozen of the other...

If you installed 2 of the timed relays you could...

hook one to the fold in wire and the lock signal of the door lock actuator..

And hook the second relay to the fold out wire and the unlock signal of the door lock actuator.

I agree whole heartedly... I was simply trying to answer the questions posed by the OP...

I would take advantage of the money being spent on reprogramming the BCM and have the turn signals programmed to be LED compatible at the same time as well as anything else I could think of that I wanted modified.

It's only about $200 to get the BCM reprogrammed so it's not very much in the grand scheme of things.

 

[MDC9966]

Yes, it does make sense, I was hoping for a DIY solution. I saw this link: http://www.whiteautoandmedia.com/in...n=com_virtuemart&Itemid=54&vmcchk=1&Itemid=54

It looks like the BCM has to be sent to them. I"m going to look around for a local source near Charlotte. Maybe I'm lucky, worst case I still have a plan. Thank you guys.

Any luck on this? I always thought this would be cool to do and why it was never automatically done at the manufacturer
