I just bought a 96 civic lx for a good price but some things are wrong. The driver side power door lock doesnt work but the other 3 do. When I hit the power switch it appears as if it is trying to pull down the lock but it doesnt move. Also, I cannot push it down by hand but it will go down when using the key. Does anyone know what the problem could be and if they do is it something a lay person (myself) can fix? Thanks for any feedback. Asilo
