Faulty windows a result of the accident?

Was the solder bridge a result of the impact or was it a glitch that occurred unrelated to the accident? I have to applaud your detective work. I wish the larger pool of appliance repair men/women and mechanics had similar tenacity to stay on a problem!

I'm curious, too, about the origin of the solder bridge. It sounds like something that either was there to start with in the factory--but then shouldn't it have caused this problem a lot sooner?--or that it occurred at the body shop during the door's post-accident repair.

I've spent half a lifetime examining mother boards and solder joints under a microscope and have often found things that make me wonder where the QA process is at many world-class companies.  Your example of solder bridging is likely root caused as too much solder on the connector joints, and further root caused to poor stencil & pad design at the PCB layout stage.  

If you're familiar with high volume manufacturing of electronics, you know that each electrical component, (in this case, switches) comes from it's manufacture with a recommended PCB hole pattern, or a recommended solder-pad  layout if an SMD device.  Its up to the PCB designer to follow the recommendation, or the "fault" can be pointed to the switch manufacture for bad solder joint design. In the case of Honda, its surprising that solder bridging is occurring on a world class car like an Odyssey.

Come to think of it, your opening line was, ",,,hit in the driver-side door".  I would speculate that the body shop may have opted for a non-factory-authorized replacement module after the factory window module was destroyed.  

Like Mr. Goodwrench always used to say, "Insist on Genuine {GM} Parts".  Third –party component manufactures have no responsibility for the overall quality of an electrical system, because they have "no skin in the game", so to speak.  They are trying only to peddle after-market modules.

I am pretty sure the body shop installed a used door and suspect that the original owners of the door had the problem since it was new.

Appliance repair men work in modules.  They will generally only replace defective FRUs.  We had a problem with one a while ago.  It was in a double oven.  The repair guy told us that the module was no longer manufactured, so he could not fix it.  He suggested replacing the oven.  Oh, by the way, the new ones were slightly different in size (same manufacturer, mind you). 

Well, I isolated the problem to a component, which would need to be replaced.  I decided to have the module repaired when we found that there were places that did that.  One of them was near by, so I took it in rather than shipping it.  It works fine now.  For about $150 I avoided a purchase of over $2,000.  It pays to fix, rather than to replace.

I don't know how hard the author was hit, or how he was hit, but it's interesting to note that minivans (such as the Odyssey) didn't have large sliding doors on the driver's side for many years because they couldn't provide sufficient torsional stiffness when they had big door openings on both sides (remember how minivans only had one sliding door a few years back?). Sounds like all that FEA work on the Odyssey's space frame did its job.

It seems that the author have a good debugging knowledge and analytical skill. The entire malfunctioning happens because of the soldering problem and it implies to the accuracy in precession soldering.

Jim, you are painting the aftermarket with too broad a brush. Virtually all of the high-mounted brakelights on 2000-2006 Suburbans, Tahoes, Yukons, Yukon XLs, and CK-1500 pickups failed within a few years. The GM list price for that part is $223.00. (The GM parts counterman said "No, we don't think it's unreasonable to replace that part every few years for $223.00.) There is no ECO on this part--they sell you the same weak-sister part that you got originally.

One very prominent manufacturer of aftermarket parts boasts that they re-engineered the part to eliminate the failure modes. Their replacement part can be had for as little as $43.00.

Which would you buy?

Hmm.  Wait until we start tracing these faults to tin-whiskers due to the misguided European RoHS campaign.

Ooops. I'm sorry.  We'ce already done that.  Look for the reports on tin whiskers in the Toyota throttle-by-wire unit.

By the way, has anyone else noted that the rich-text posting editor doesn't work. My last post used the indent feature, but the indent was once the post went live.
