From what I read, the problem is caused by the vendor testing with a load too large. And that impacted a transistor.I figure I'll get it fixed in the future when they are caught up on others perhaps and if it goes out. Seems like 98% of wipers in trucks work just fine so odds are pretty good it'll work just fine. Haven't had to use in the rain yet, kinda looking forward to that. Just had the odd wipe here and there by itself on the freeway so far. Makes that horrible squeak sound on dry glass ;-)
Transistors are far from identical, in any batch you will have ones that far exceed the specification and some that minimally meet the specifications, but indeed meets them.
I suspect that the problem is that the weaker transistors ended up being stressed a little too much. And they may make a few cycles before giving up.
But the stronger transistors are still happy and will keep going forever.
The problem is that the way that you determine which is marginal and which are not, is destructive.
So you got to change them all!
