My wife is looking to have a remote start installed in her '05 Armada. I've been digging around here and ClubTitan and haven't found a whole lot of info. Best I've found so far is this walkthrough: http://www.clubtitan.org/forums/showthread.php?t=26260 .
One thing (obviously) not addressed there is the power liftgate. I don't see it on either of the two wiring diagrams I've found either. Has anyone wired their liftgate into an aftermarket remote start? Wire location? Type of trigger?
My Viper ( or any of the other serpent) remote starters with an aux button can be programmed to work the lift gate. Mine has been working great for about 5 years!
TRUNK RELEASE Blue/white At release switch in dash
That's what I could find for a 2006... which I would assume is the same for 2005
I just did another remote start in my 2011 so it was a little easier because those functions are controlled by the interface module
Thanks. We actally had a dealer install one on Wednesday
He was able to hook up the lift gate, but we noticed something interesting. The liftgate won't open while the car is running on remote start. Anyone know of a way to bypass this?
My dealer installed remote start (Audiovox I think) won't start the radio or lift gate.
I have to put the key in the ignition and press the brake peddle in order for the lift gate to work. Funny thing is, if you press the button on the dash nothing happens - until you put the key in. Learned that the hard way.
From what I understand, you have to hook up separate devices to the remote start. Sure wish those two were hooked up as my Pioneer Navi takes forever to boot up and the ability to open the lifgate would be nice.
Our Armadas have two accessory wires coming from the ignition. If only one of those wires are given power from the remote starter, all of the accessories tied to the other will not function until the key is in giving it power. Some remote systems have the ability to run a second accessory out of the box and some require an additional relay to be added. It sounds like one of the accessory wires is not hooked into your remote start for your radio as well as the power lift gate.
The key to knowing which functions are supported by the remote start are the ones supported by the factory. If the power lift gate works with the button and the key on, there is no reason it shouldn't with the remote start. If the radio powers up with the key on, there is no reason it shouldn't with the remote start. Sounds to me like the installer was a tad lazy...
Messed with it some this morning. No luck while remote started locked or unlocked. So I gave up and went to work...
Well, I just got a call from the wife - apparently, the remote start timed out, and when it shut off the liftgate opened.
She also said it was unresponsive to the buttons, just like you said spta97.
Olds67 - The lift gate operates via remote just fine as long as the engine is not running on remote start, so I'm pretty sure everything that needs to be powered is. <shrug>
imtfox - I know my installer well and he seemed to be familiar with needing to have the remote start shut off to operate the liftgate. Have you had luck getting it to work?
