Hello i have recently replaced the automatic door lock mechanisum in the car door, it was working only sometimes for the driver side door so i thought i should replace it. Well i got one from the junk yard and installed it and now it wont unlock or lock both front driver and passenger side locks and i never toched the passenger side one. The back locks work just fine with the keyless and the buttons on the arm rests. I did try putting the old one back in the door to see if it was the one from the junk yard but it wont work now either im wondering if i blew a fuse but wouldnt all of them not work not just the front. If anyone has a qlue i would be vary happy as it is vary annoying. Oh yea in the door the wire harness there has 3 other plugs and well i only need one, at least thats all i unpluged when i started the project. I one i pulled from the junk yard i t has the same plug that i took off the old and another connection that 1/3 that are there can plug into it. So old had 1/3 of the connections connected the new one i am able to plug 2/3 into it or is that were i caused the problem pluging in both when i only need the one.
