alt Hacker NewsI think the point is that all those "dumb" switches, terminals or cables that get worn out can be replaced relatively easily (ie you need a multimeter and some patience to find the bad one). But if something in the integrated module fails, well good luck repairing that. These things are probably designed to be replaced as a whole, which is fine if you can get a new one. But as the cars get older, this is going to be a problem.
Strong old-man-yells-at-cloud vibe, I know. ;)
Yes but specifically, in this article, the passage is written about a harness connector on a door window switch module as follows:
This just reads weird to me.Corrosion on an interior module connector is not as much of a concern these days unless the car is in a flood or the door card sealing is broken due to something like a poor repair job.
Fretting? What would cause fretting on pins of a connector that never gets touched by a human after it leaves the factory. It is a static connection, it doesn't get plugged and unplugged.
Thermal cycling? It is inside a door panel... not near a hot exhaust or inside an engine. It sees normal interior temperature cycles.
An actual Closures Engineer would more likely call out vibration shock during door slam in a closures FMEA as a potential electrical window switch fault hazard resulting from the connector loosening if the chosen connector lacks sufficient mechanical fastening moreso than anything..
Saying that connectors themselves are "among the most common failure points in modern cars".... just sets of flags to me as overly flatulent, generated puff writing. "Oh I need to list three things about connectors (thinking).... Corrosion -Fretting- Thermal Cycling-!! and this makes connectors among the most common failures in modern cars (no sources cited)".
