Door Lock problem - 2000 - F150 Lariat
I installed a aftermarket alarm that took over contol of the door locks. It was wired into the existing control module now after a few months the door locks do not work correctly. Sometime they work depending on the weather. I disconnected the aftermarket alarm controls but it still does not work. I am wondering if the problem is with a relay or the control module under the dash. I am pretty sure it not the actuators since the doors lock when you put the truck and gear and remove your foot from the brake. I assume this security feature is on another circuit. Any help would be appreciated. I did see a earlier post on this subject but I could not find the link in the forum.
