I have a 96 that I just purchased and I am having problems with the passenger door latch. It open fine from the outside but from the inside it will only open to the first latch (part way open or closed). The power door lock button will not operate but it will operate mannually. The "Door Adjar" light remains on all of the time on the information screen. Wehn you operate the power door lock button you can hear a motor running but nothing happens. I tried sprying WD-40 in the latch assemble last weekend but it did not help. Any suggestions?
