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!
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!!
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.
