Miata MX5 automatic headlight housing problem

Our Mazda Miata MX5’s automatic headlight housing will not come up. We’re concerned that there is a loose connection in the “housing block”. Tom truly doesn’t want to replace these blocks & wanted to know if anyone’s ever had to replace some of the wiring of the “connectors”, & what results were attained. He feels that when he goes to test the electrical connections of the “ity, bity, very, very small connectors”, he’ll need to do this. While he understands that he needs to clean & test the connections, he’s hoping it’s just a wiring issue that he can fix him self.
