Hi everyone. I have an interesting problem, and wondering if anyone has experienced the same thing, or has a fix for it. My driver side power door lock will not go up and down anymore. I have to lock it and unlock it with the key, which kinda makes my keyless entry option useless. Anyone know a fix to this, that doesn't require a dealer? How involved is it?
Well it could be as simple as a fuse that has blown for the door lock functions. But that will affect both. If you are only having an issue with one then look at the control module in the door and make sure it is getting power. If it is getting power make sure that the bx itself is functioning. If not then replace that. IF it is then look at the connections from the box and the pin itself. They may be obstructed or damaged.
Most likely it is the module in the door that has failed. That is the most common failure.
Where exactly is the control module in the door? The most that I have ever done is take off the door panel to put component speakers in the door. I'm not sure how to start taking things off after that.
Can you operate the locks from the powerlock switch internally? If yes then it is not the locks or modules themselves. I would look at the remote or the ford security system itself. If no then you can assume that it is either a bad wire, bad fuse or dead module in the door itself.
Now this is a really stupid question...i should have asked this earlier, but I just assumed and thought you might have checked it...So instead of assuming I will just ask
Have you checked the battery in your remote? No? Then do so. If yes read on.
If you have replaced the battery did you reprogram the remote to be accepted?
If you did not try this.....
This procedure works for 1998 + Mustang models
Cycle ignition from OFF to RUN or ACC eight (8) times within ten (10) seconds, ending in RUN. All doors will lock then unlock to confirm programming mode. Press any button on 1st remote transmitter. Door locks will cycle to confirm programming. Press any button on 2nd transmitter (up to 4 total transmitters possible). Turn ignition to OFF. The door locks will lock then unlock to confirm programming
These instructions will work on Mustang models pre 98:
Inside the trunk, pull away the carpet on the driver's side to find the anti-theft box. This box contains a gray plug, which contains 2 metal prongs. Go put your key to the "ON" position and jump the two prongs together. You can use anything that will hold an electric current; I used a pair of plyers. Now all you have to do is press any button on your remote transmitter. Once you do this, your car will lock and then unlock. This lets you know the the programming was a success. This can works on most newer mustangs as well and I have done it with my 03 cobra.
If you have reprogrammed it may not have taken. If it has then It could be the remote that is the failing point here or even the control unit for the security system itself.
Security Control Unit: Best to go to the dealer to have this serviced.
Pinched/cut wire: Check the loom that is at the door hinge area. make sure that none of the wires are pinched or cut in that area. If they are not then take the doorskin completely off(be careful of the tabs they can break easily.) Once that is off look at the wire loom inside the door itself. Check to see if there are any pinched or cut wires there.
Door lock solenoids in door:
I am assuming your car doors have not received any recent dents or other reason to suspect foul-play in the linkage. This is a fun one. These are not easy to replace. The solenoids sell for about $40-$60 depending if you get them online or at the dealer. When you replace them, you will find they are held in place by a spring-steel "clamp" that is riveted to the door panel. The rivet is huge and takes a special air powered rivet gun to replace. Leave the rivet and clamp in place and use a screwdriver to pry the old solenoid from the clamp. The trick is getting the new solenoid into the clamp. Dont know how to really explain how to go about doing this without just showing you by hand. It is NOT EASY.
FUSES: Double check all fuses under the dash and under the hood.
I can operate the locks from inside the door. The passenger side always works. However, sometimes the drivers side works, and sometimes it doesn't. I makes sense that it might be a loose wire. I will take it apart and check it out tomorrow. If I don't find anything I'll dig deeper. I'll keep you updated, and thanks for all your help!!!
