    Guys, I am tapped out on ideas about why my power door locks dont work... ive read thru all the other related posts, ive done lots of testing and stuff but there must be a gremlin in this car... heres the scoop.
    The power actuators do not function at all, if both doors are locked, and you push the unlock button, the control box relay clicks.. nothing happens.
    If both doors are unlocked, and you push the lock button, the control box relay clicks.. nothing happens.
    If you lock or unlock the driver door manually or by key, the control box relay clicks.. nothing happens.
    I first assumed that by some miracle BOTH actuators were bad... so I got new ones, but before I went thru the nightmare of pulling the originals out, I took off the door panels and just connected them to the pigtails... same exact results.
    The car does have a Clifford alarm, but nothing from the alarm unit is tied or spliced into the locking system wiring.
    One thing I did discover in my testing is that the blue wire does get a 12V signal when the lock button is pressed, but there is never 12V on the red wire (which should be the unlock + signal) even though the relay is activated. I also cleaned all contacts to all connections, but they were'nt the least bit corroded or anything.
    Auto wiring and electronics is my specialty, so I totally understand the concept of how a central locking system works, but
    I dont know what else to look at, so I guess the problem HAS to be in the control module, but does that make sense if the relays are kickin correctly??? i'm begging for your expert opinions!

    I'd suspect the wiring at the intersection of the inner front of the door and front frame. Look behind the circular black plastic Amp connectors on both doors.

    Common problem.

    For starters I would have a look at the connectors inside the door jam as No Doubt suggested. Then I would remove the alarm system and see what that does.

    My opinion would be that the problem has something to do with the Clifford alarm, unless you installed it yourself, or you know for a FACT that the person who DID install it didn't mess around with the power lock wiring. Where is the control unit for the Clifford installed? Under the dash? In the center console? Do you know the color codes for the Clifford unit, and you know for sure that none of the remote door lock wires are hooked into anything at present, and have never been hooked into anything in the past?

    ok, No Doubt wins the prize... i took those door AMP connectors off and sure enough... 3 broken wires from the pins between both sides. One being one of the primary activation wires to the driver door actuator. There was only 1 broken wire on the pass. side, white w/black stripe... its not related to the door locks, but everything else in that door worked even tho that wire was broken.
    Anyway, I screwed around with my soldering iron for a couple hours a feel like I fixed them... now the driver door lock is working, but the passenger side still does nothing... so I guess i'm at least making progress.
    The real question is, whats the permanant fix on this? This is a totally half-assed setup, and I know more of these wires will keep breaking off as time goes on... I'm also afraid that maybe some of the wires are broken on the back of the body side of that connector, how should I deal with this as a more solid fix? is there an upgrade or improved way of resolving this? maybe pull all this out and just splice the wires together?

    BRILLIANT!! run the wires thru the holes where the pins were!!... I was pondering on how to splice and still be able to attach the flex-tube and not look stupid!! you guys ROCK!!! I promise that as time goes by, and I have more time with this car, I will ba able to contribute more around here instead of just being so needy!

    Just one thing tho... how do you get the pins out? AND I twisted that big nut on the body side of the connector back & forth 20 times... but it wont come out! Whats the secret there?

    PS. one thing I can contribute right now is, I found an "add-on" central locking kit on ebay that includes 2 5-wire actuators AND a control box that will directly replace the Ferrari stuff... you just have to make a simple harness adapter with male blade connectors to hook up the control box. It even has a connection to add a keyless entry lead to activate it. It only costs $32 including shipping. So if anyone has thier control box or actuators go bad, i'm sure even buying this whole kit is WAY cheaper than ANY of those single parts from Ferrari!!

    You can get to the back of it by removing the front wheel well liner.

    but how do you get the pins out of the connectors? I know that AMP makes a nifty release tool for them, but is there a "backyard" easy way to get them out?

    Brute force. LOL!

    Actually I really don't know. I haven't tackled this yet on my car.

    Where is Plugzit? That boy has take them out, but he has the tool. I think he bought one for $20 or something like that. How did you get them out Jeff?

    Ripped 'em out. Grabbed 'em with pliers, twisted and pulled. Didn't intend to ever re-install pins in the holes, so I didn't care if the holes got bunged up a bit. A few of the holes needed to be drilled oversize anyway, in order to get 14 gauge wire through them. I don't recall if I mentioned this in the earlier thread, but it doesn't matter which wire goes through which hole, as long as you reattach both ends of the same wire. All that matters is that you make good solid connections that will stay together and allow full current flow. Haven't had any problems so far.

    Well, I tore into this today... I took a slightly different approach. I cut all the wires off both sides of the connector, the used a 3/4'' hole saw and drilled right thru the whole connector. That took care of all the pins!! The entire connector is still in tact, theres just a big hole in the middle of it now... this way the wires cant bind up or anything. I'm not done yet, taking pics as I go... i'll have it finished up tomorrow.

    hehe thanks Ernie! i'm just trying to pioneer some ways to contribute around here... Sometimes I just need a ''suggestive'' kick in the pants to get me brainstorming! ;-)
