I have a '03 Ford Focus. About a year ago, I noticed that I could no longer unlock the driver door with the remote, or power door locks. We took the car to our mechanic and they said that we needed a new GEM Module(about 0). We opted not to get a module. I've noticed that it will sporadically work with PDL, but then it will quit. I'm wondering if this is really a GEM Module problem. Note that all the other doors will unlock automatically and the driver door will lock automatically, it just wont unlock. Thanks!
