trying to check for bad wires in the harness connector WOW thats a hard part to get out any sudggestions

 

Best way is to pull the boot off one end, slide it back, and inspect the wires. Trying to probe the connectors can be futile sometimes. I had a broken wire in my driver's door harness that worked with the door closed, but not with it open. My friendly mechanic's body man had it fixed in 10 minutes.

 

I did what dave said. Just slid the boot back from the door, towards the frame and wedged it there. I "gently" tugged on each wire until the black one came apart. The wire insulation was probably keeping it together, while the wire itself had creased to the point of not connecting. I added a short length of wire, same gage, and soldered it back together and shrink wrapped it. Some peoples pull the connector and replace the whole wire. I didn't.

 

That was very smart! If you just soldered it together, it would be flexing at that point and fail again! By adding a section, you restored the section that flexes removing the strain. I've heard of guys who just used a crimp connector, making it solid right where it is supposed to flex!
