So I know there has been countless threads out here on the power doors, and I do believe that I have read ALL of them, and have yet to spot my problem. The drivers sliding door will open fine with all buttons while the ignition is off (remote, pillar, and overhead). Now with the ignition on I know that the remote is made not to work, so that takes that out of the equation. That leaves me with the overhead and the pillar buttons. I know for a fact that the lock is not set, and the child proof is also not set behind the sliding door as I have checked both of these things. The problem itself is that the slider won't open by pushing the pillar button when the ignition is on. It will only open from the overhead button. The passenger side slider will open by pillar button or overhead button just fine. I don't think the button on the pillar has gone bad because it works fine with the ignition off..... Any suggestions?
