I had a similar problem, but my locks wouldn't work at all. Try checking the vaccum hoses in the doors to see if any are disconected. that was my problem. To get to them you just have to remove the rubber that covers the elecrical wires between your door and the chasis and then you shoud see a bunch of wires and a plastic tube(the vaccum hose) make sure that it is in the hole on the plastic harness on the chasis.
