I have a 98 LTD that originally had a factory alarm. A few months ago the alarm started acting goofy so I removed it. Now my drivers side door will not lock or unlock when I use the power lock button. I can lock it manually but it does not respond to the console button. I took the door off and replaced the actuator with no success. While I was in there I checked with my volt meter and the 4 pronged connector did get a 5V stimulus when I hit the lock button. So i'm thinking that it is somehow connected to the alarm that I removed? I looked all over the forum and saw lots of problems with the locks, but couldn't find anything about the alarm being part of the problem. Suggestions? Thanks!!
