SDA CRS question

I have a pair of SDA CRS speakers I bought new in 1985. Well cared for & excellent condition. In each speaker I must a have bad connection internally & need advice on how to fix. I will use my left speaker as the example. The driver & tweeter on right side of the left speaker are not working, if I disconnect them & hookup to the left side of the left speaker they work fine. I have the same issue with right speaker on the right side.

Any suggestions on what I need to do to fix the issue?

Speakers are driven by my NAD 7140 receiver I bought at the same time in 1985. Currently using my backup Polk 7’s until I can figure this out.

Thanks!

    SDA connectors are the issue. I’ve cleaned the blades, they did have a flim residue on them. Cleaned plugin best I could. They work but dropout intermittently, if I giggle the cable they come back. I will spread the blades slightly like was suggested & hopefully that will solve the issue.
