Default electrical connector pin removal tool

My D-door switches have all ceased to function (although they do light up). I found some corrosion on the connector which joins the door panel to the door (big multi-pin with blue lever lock). Has anyone found a pin removal tool for this connector? I want to back the pins out and clean them (spraying contact cleaner did not work). A friend said Harbor Freight had a cheap one but I couldn't find it. Is there an AC delco gizmo for this?

looking at one of my spare front door harnesses it appears that once you have it disconnected from the main car harness if you look where the wires go in to the back of the plug the blue plastic wire holder will come out if you release the locks on the sides of the plug. pic to follow

It usually requires a specialized extraction tool for those particular pins. I used to repair equipment in a wafer fab, and I had various ones for different diameter Molex pins. Specialized crimpers and extractors for Winchester connectors, and the list goes on.

That'* not to say you can't get the pins out without the tool. The locking mechanism is often a small metal tang that protrudes from the pin to lock it in the housing. A small jeweler'* screwdriver is usually able to slip between the connector and shell to push down on the tang and release the connector. Just note that you often need to manually bend that tang back up a bit when re-inserting the connector so that it locks in place again.

The specialty tools are spring loaded and have an outer barrel that depresses the tang while the inner solid portion ejects the pin. They are sized for the connector you need to remove. It'* not a one tool fits all kind of thing.

Hope this helps.

Once the blue pieces are out, I use a sharp pick or something of that nature. Overall there'* a little tab that sticks up to the back of the connector. If you slide the pick in from the pin side (front) of the connector you can push that tab up and remove the wire. I did some last night and should be able to take a picture tonight if you would like.
