How can I tell if I have power door locks?

Hey everyone. This is my first post on here (actually my first power EVER in an forum, period). I'm excited to hear from everyone and can't wait to learn more about the Jeep family
I am the owner of two wranglers; 1989 YJ Islander, and 2006 LJ Unlimited. The 89 was my first car and we kept it in the family for the past 10 years (slowly my dad and I are modding it). I went off to college in a ford expedition simply for safely and the ability to lock my goods in it.
I recently bought my LJ (used obviously) and love it. However, I noticed that there are two wires (blue and green) that come from the door and are cut. I heard that blue and green wires are used for PDL's, but is there another way to tell if I have this addition without ripping the doors apart? When I purchased the Jeep from the dealership they only gave me the fob for the Python alarm system.

Thanks in advance!

No TJ including "LJ" came with power door locks or power windows so unless aftermarket not there

That is only in JK wranglers

With your vin you can get a complete build sheet for any TJ/LJ that lists all the options it came with just put in the vin and your build sheet pops up that quick and easy

Thanks, Digger.
The list is pretty cool. Helps me see what I currently have. But I still don't see why the green and blue wires are severed.

I guess Ill have to remove the door panel.

JonBomb44,
He's right, not one Jeep Wrangler, that was made prior to the JK model, EVER came with Power Door locks or, Power Windows. The JK was a new era in "glitzing" the Jeep Wrangler. I recently added both, PDL and PW to our '03 Rubicon. So, here's a couple of suggestions.

1. You can supply 12V, positive to one wire and negative to the other, and listen and watch to see if the door locks work. If not but, you hear a minor "click" all that means is, the polarity you supplied, is making the PDL motor try and do what it's already sitting at, either locked or un-locked. If you reverse the wires, put the positive on the other wire and the negative on the other wire, you should see and hear and feel, the door lock, or un-lock, depending.

2. If you don't want to try the 12V trick, no biggie. What you can do next is, remove the bottom, outboard screw (Phillips head) from the door panel. Then, with a wide bladed flat tip screw driver or, a stiff blade 1 1/2" scraper, wedge it in between the door panel and the door steel. There are plastic "barbs" that attached to the plastic door panel that are stuck in holes of the inner door skin. What you will do is, "POP" one, possibly two, of those barbs loose.

That is no big deal as, when you've finished what I'm going to tell you next, you just push on the plastic door panel to re-insert those plastic barbs, back into the inner door skin. Anyway, once you pop that corner of the door panel, it will be flexible enough to pry it away from the door for at least a couple of inches without fear of breaking any part of it.

What you'll see is a very thin, plastic visqueen sheet, attached to the inner door skin, via a type of butyl gummy material. That visqueen is a sound/weather deadener. All you'll do with it is, peel it away from the black butyl for a short distance in either direction from the corner that you are working at.

Once that's done, you will reveal the opening in that door skin where, the only possible place the door lock motor can be mounted. If you have one, you'll be staring right at it.

Now, what you do from this point on, is entirely up to you. What I mean is, it all depends on what direction you want to go. The operation of a power door lock requires a sender/receiver, normally associated with an alarm system of some type. Not always but, normally.

If all you wanted to do was verify that you do or, do not have PDL, then you can reverse everything I just told you and button up that door panel and you're done. I suspect that, if you've got wires showing, eminating from the front edge of the door panel, that you do have the PDL, at least in the drivers side.

Again, from this point on, you'll need to decide what you want to do,
1. Leave it alone
2. Dig around under the dash to see if you have sending unit that is supposed to be hooked up to those wires.
3. Figure out if you want to try and make it work which, without all the proper sending/receiving units and, tied to the ignition system, is pretty hard to do.

If you decide to leave it in there and do nothing about it, what is happening each and every time you lock or unlock that door, you're manually moving that door lock motor. That in it'self, is not too big of a deal. But, you're moving added mechanisms that are making it hard on your key, when you stick in the outside door lock. The more work that key has to do, in order to lock or unlock that door lock, the weaker it gets over time.

Eventually, there is a real high possibility that you will break the key off, INSIDE THAT DOOR LOCK!!!! That my friend, IS NOT A GOOD THING!!

Your choice.
Scott

P.S. Below is a picture of what you're looking for when you open up that lower corner of the door panel. You see the accordian type plunger in the picture? That's the actuating rod of the motor that it's attached to. The rod that extends from that accordian bellows, attaches to the regular door lock rods, via a small/tiny clamp. When the plunger goes in and out, it also takes the original door locking mechanism with it, to actuate the door locks.

Wow! Thank you so much for the detailed information. I will be sure to follow through with this and let you know how it goes.
Funny how you mentioned that the key could possibly break. I forgot to mention that the lock is jammed on the driver-side. I can not use the key to turn the lock. The previous owner must have had a similar issue.

I will add some photos of what I am talking about.

The blue and green wire are present with both driver and passenger doors.

Well,
If the blue and green wires are present in both, then unless there's some other motorized mechanism or, hidden speakers, I suspect you do have PDL in both sides. Now, the big question is, WHY were the wires cut? Is there an alarm system in your jeep? And if so, is any part of it functioning?

Did the previous owner mention ANYTHING about an alarm or, PDL or any reference to your cut wires? If there is an alarm in your Jeep, and, it's partially wired in/up to your ignition system, there is a possibility that that alarm system CAN malfunction and, leave you and your jeep, stranded some place.

You see, the reason I tell you all this is because, the '03 Rubi we just bought last Thanksgiving had the same exact situation as you are experiencing right now only, my door wires weren't cut, they actually worked and I had only ONE PDL.

But, my "alarm" system, malfunctioned one day while the wife and I were roaming around and, the Jeep would not start. I tried and tried and, it finally started. So, when we got home, I parked it 'till I could determine just what was wrong. Well, I popped off the panel that's under the steering wheel (very easy to do with two screws and just lightly pull on that panel and it pops off.

And there is was, a VIPER alarm system with a ton of wires, very poorly wired into the ignition and other parts of the Jeeps wiring. Guess what I did, IT GOT RIPPED OUT OF THERE INSTANTLY!! I rebuilt the damaged factory wiring to the point it looked like the Viper was never in there.

I feel way better that, I took the time to yank all that out of there and clean things up.

Unfortunately, I got the Jeep from a wholesale dealership (on 12/31/15.) The salesmen knew NOTHING about its specs. They hardly knew anything about jeeps in general.
What I do know is that it is equipped with a PYTHON security system and I have the fob for it. I can activate and deactivate the system, and, if there was an entry to the vehicle with the system armed, it will prevent you from starting ignition. I tried to look up the possibility of Python having PDL capability but came up empty.

One previous owner probably installed the power door locks. The next owner probably didn't get the fob and was more interested in driving with the doors off and cut the wires.

That was the case for me: the driver's side door had a power door lock but the previous owner never got the fob from the first owner and so had no idea what the wires going into the door was for. I opened it up, found the mechanism, had no interest in that functionality or an ability to use it, so I cut the wires and tucked them inside the door.

I have been so busy working (Im a high school teacher and track and field coach) that I haven't gotten around to checking it out. I'm sorry for not following up sooner, but I promise I will update you with what I find.
Thank you again for the detailed responses.

We are actually working on another situation with our '89 YJ. The ignition switch is glitchy. Just this morning I stalled out, went to start it back up, but no turnover. This situation is taking over the time I wanted to have to see the sources of the wires in my TJ.
